how to Step through Catel code while debugging ? - silverlight

After adding Catel implementation to one of my views(mainPage) in my project I have a bug that crashes my Silverlight project. The only indication I have is :" A first chance exception of type 'System.NullReferenceException' occurred in Catel.MVVM " (just about after setting the RootVisual~) - I can't find what I'm doing wrong, and since I am planing on a long-term relationship with Catel I thought that stepping through Catel code might come in handy, so I tried and failed in all the following steps (any help will be appreciated.. because currently I'm stuck and can't find anything):
downloaded catel 3.9 source files (same as my nuget package) and tried building it.. failed with this error :
E:\Dev\Catel-3.9.0\src\Catel.Core\Catel.Core.SL5\Fody.targets(51,5): error MSB4036: The "Fody.WeavingTask" task was not found. Check the following: 1.) The name of the task in the project file is the same as the name of the task class. 2.) The task class is "public" and implements the Microsoft.Build.Framework.ITask interface. 3.) The task is correctly declared with in the project file, or in the *.tasks files located in the "E:\WINDOWS\Microsoft.NET\Framework\v4.0.30319" directory. - trying to search and figure the reasons and overcome this, lead me to nowhere. :(
i have followed this "Stepping through the code" instruction in Catel documentation but noting really happened (I'm using VS2010..is this an issue ?? )
I read this article & readme.md at : https://github.com/GeertvanHorrik/GitHubLink about using GitHubLink to help you stepping through Catel code while debugging. I downloaded the release GitHubLink 1.3.0 from https://github.com/GeertvanHorrik/GitHubLink/releases/tag/1.3.0 ... but running this even with just the githublink.exe -help flag had thrown a exception..
I downloaded the Githublink-master source files but 0 projects were loaded (the GithubLink project file is incompatible with the current version of VS - I'm using VS2010)
can anyone help me either shade some light or:
overcome the build error I receive for catel (no.1)
instruct me how to set & step into catel ?
share the pdb files for Catel libs

It completely depends on the version you are using. If you are using the latest official one (3.9), stepping through the code is only possible by cloning the master branch and building the PDB files yourself.
In the latest prerelease versions via NuGet (the upcoming 4.0 version) you only have to enable the source server checkbox.
Note that you should never have to use GitHubLink yourself, that is for developers only (we run it during the build of Catel).
About the Fody task: it looks like the NuGet packages have not yet been restored on your side. In the lib folder there is a RestorePackages.bat which you can run to restore the packages.

I tried debugging on VS2012 and using Catel 4 pre-release (from Nuget)..
although I believe I did all the right things & settings in VS, I didnt get much further..
So I Opened (using a bin editor) the pdb file that was pulled by Nuget with the DLL, and took a look at the bin file.
the file have strings pointing to the source files at this directory :
C:\ci_ws\WS\1629\source\catel\src\catel/mvvm\catel.mvvm.shared..
So I have created a tree that starts with
c:\ci_ws\ws\1629\source
and downloaded the catel folder to that dir, renamed it from
"Catel-Develop" to just "Catel" in order to feet the location the pdb pointed.
To get things going I also had to add a "Symbol File(.pdb) location" in VS
option-> settings->Debugging->Symbols..(location/server list) to where the nuget download the packages.
in my case.. SolutionFolder\Packages\Catel.MVVM.3.9.0.1406062245-beta\lib\sl50..(I'm using Silverlight)
and then I was able to load the symbols and step/break into the code successfully ..
Maybe I missing something and there is a better way, but this the only way that worked for me..
The only question that still remains for me now is : What is the name of the Catel Github source branch that is matching the pre-release dll and pdb that Nuget is publishing at the moment (3.9.0.1406062245) ?
(I unchecked the general debug settings of : require source files to exactly match the original version)

Can Fody and its plugins be used with .NET Core (3.0)?

As the title says, I'm having trouble getting Fody, and the plugin Fody.PropertyChanged, to work in .NET Core 3.0, or any .NET Core version. Reading the issues on the respective GitHub pages doesn't answer my question, nor am I able to find any relevant answers.
Once installed I cannot run my WPF project anymore and I am given the following error:
The target process exited without raising a CoreCLR started event.
Ensure that the target process is configured to use .NET Core.
This may be expected if the target process did not run on .NET Core.
The program '[21820] CalculationToolsApp.exe' has exited with code -2147450749 (0x80008083).
Any suggestions?
EDIT: I found out that I (maybe) cant use "Fody.Costura" with "Fody.PropertyChanged" like this in the FodyWeavers.xml file:
<Weavers>
<PropertyChanged />
<Costura />
</Weavers>
Which shouldn't be a problem because with .NET Core I can create a single file application anyway. Removing the Costura reference from the FodyWeavers.xml solved my problem!
It should work. Fody is compatible with .NET Standard.
Create a new WPF app using the WPF App (.NET Core) template in Visual Studio 2019 or using the dotnet new wpf command
Install the Fody and PropertyChanged.Fody NuGet packages
Add a file named "FodyWeavers.xml" with the following contents to the project:
<Weavers>
<PropertyChanged />
</Weavers>
Build
If you then decompile the assembly using a decompiler such as for example dotPeek, you should see the injected code as expected, e.g.:
public string GivenNames
{
// Method get_GivenNames with token 06000009
get
{
return this.<GivenNames>k__BackingField;
}
// Method set_GivenNames with token 0600000A
set
{
if (string.Equals(this.<GivenNames>k__BackingField, value, StringComparison.Ordinal))
return;
this.<GivenNames>k__BackingField = value;
this.<>OnPropertyChanged(<>PropertyChangedEventArgs.FullName);
this.<>OnPropertyChanged(<>PropertyChangedEventArgs.GivenNames);
}
}
Costura didnt work in wpf with .net core 3.1 for me either.
In .net core 3.1 you can use this instead:
Build -> publish -> create profile -> Edit "Configuration"
Target Runtime = win-x64 (or what ever target system you want, but NOT "portable")
expand "File Publish Options"
check: Produce single file
save
When you now choose build -> publish -> publish button it will create the single file.
It seems to be that they stopped the costura project because of the "Single-file executables" feature of .net core. Though this feature is still behind costura because you have to set a target runtime.
https://github.com/Fody/Costura/issues/442
In dotnet core 3 there are two new features
Single-file executables
Assembly linking
With these features included in the dotnet tool set, the value
proposition of Costura is greatly diminished. With that in mind I
think long term Costura should cease to be used as people transition
over.
Please comment with any input.
Plan:
disable issues
PR will still be accepted but only for bug fixes
add note to readme
add note to nuget description
write a warning in
update for .NET 5:
for .NET 5 and the current visual studio version 16.10.2 the wizard changed. I could not get this to work with the wizard anymore though i checked the options for single file etc.. But using the console worked: tools -> command line -> developer command prompt -> enter this:
dotnet publish -r win-x64 --self-contained true -p:PublishSingleFile=true -p:IncludeAllContentForSelfExtract=true
.NET 5 not compiling to single file executables

Xcode 9.4 : unexpected service error: The Xcode build system has crashed

I’m getting strange error while building project in Xcode 9.4
Build system information - unexpected service error: The Xcode build system has crashed. Please close and reopen your workspace.
I tried Xcode quit and reopen but that didn’t worked. Any solution?
Please clear derived data folder (located at ~/Library/Developer/Xcode/DerivedData) and restart the Xcode project.
This error usually happens between Xcode major versions. Apple usually claim their new build system is ** times faster than their previous version. If you see this error(I see this on changing Xcode9 to Xcode10 beta), you can always change it to the legacy build system. Here is how you can do this:
Open 'workspace settings'( it is now changed to 'Project Settings' if you are using Xcode10 or later) in the File Menu
Change build system to 'legacy'
Update for Xcode 13.4.1:
I had this infamous bug today as well. I tried a lot including clean project, delete derived, restart max etc.
What did the fix finally is similar to the answer of kakaiikaka: I set the workspace settings to "Legacy Build System (Deprecated)" for both, the shared and per user workspace. I tried to build with this, but got an error because I had packages wich are not supported.
Restarted Xcode, then changed back the build system. Restarted Xcode again.
Now the crash doesn't happen any more.
Looks like something internal was spoilt and cycling the build system fixed it.
I moved a lot of files all at once between folders, including nested folders. This error started happening. Nothing I did in regards to cleaning, purging derived data, or undoing the move operation would help.
What I did to help was: restore the previous version of the project file from source control and then re-add all the applicable new files to it. It was project file related. Deleting user data inside the project container did not help in my case. So as long as you use source control and can rollback the .xcodeproj, this may be an option.
it happened to me when i changed build configuration names. After deleting Pods folder and Podfile.lock, and then runnnig "pod install" fixed the issue.
For Xcode 10.2 delete podfile, podfile.lock, xcworkspace, open terminal, cd directory of project, pod init, add pods you want to pod file, pod install, open xcworkspac. Everything will be indexing now and then you can build.

Cannot install appx through graphic installer

I'm facing a problem right now and I don't really know how to get more informations about it.
I've converted a desktop application through Microsoft's Desktop App Converter, made some manual modifications about the visual assets, and rebundled it through "makeappx.exe". Then I signed it.
Everything went fine. Except that when I double click the appx to check it, I have the following window:
Appx Error
Which roughly translates as "Couldn't open the appx or appxbundle file" and "Reason: Failure caused by an unknown reason".
This does not helps me a lot :/
However, if I try to install the package through a simple "Add-appxpackage MyPackage.appx", it works perfectly fine.
Could anyone help me find some leads on what's happening here? I've already checked the event viewer as explained here but I couldn't find anything unusual.
Thanks,
Skefrep
It seems the Microsoft team has taken notice of this problem and investigated this appropriately.
-Here is their solution-
The problem can be because when you convert an app with DesktopBridge the resources are signed with the manifest info and store that info in the .pri files you found in PackageFiles folder. Later, when you change something like the Publisher or the Name this signature doesn't match. To fix this you only need to recreate the .pri files.
rm *.pri. Remove the old .pri files.
cd C:\foo\PackageFiles\. Change current directory to the PackageFiles folder. This step is important for the next step.
makepri createconfig /cf priconfig.xml /dq en-US. Create a configuration file for the resources.
makepri new /pr "C:\foo\PackageFiles" /cf "C:\foo\PackageFiles\priconfig.xml". Generate the new *.pri files.
Then you can make the package as usual: MakeAppx, etc.
You can find more information about this problem in "Failed due to unknown reasons" error when you try to sideload a Desktop Bridge app - App Consult Team.

Problems deploying SecureInput MS Edge Extension native messaging sample

I am trying out SecureInput extension sample that demonstrates NativeMessaging capabilities in MS Edge browser extensions and I running into problems deploying the extension after building using VS community edition 2017. I don’t have Universal Windows Platform Apps development experience, so I apologize if there is a pretty obvious answer I am not aware of. But following readme.md in the sample doesn’t work, so posting this question here...
https://github.com/MicrosoftEdge/MicrosoftEdge-Extensions-Demos/tree/master/SecureInput
Steps followed…
Turned on developer mode in “Use Developer Features”
Turned on Enable extension developer features in Edge browser’s about:flags.
Downloaded the sample as a zip file to the local machine.
Copied SecureInput.html to my local webserver
Loaded SecureInput.sln in VS
community edition 2017 Out of two options.. InProc or OutOfProc, I
wanted to try InProc. So needed to select Project in
NativeMessagingHostInProcess in Build Configuration manager. Other
settings used... Debug - configuration; Any CPU – Active solution
platform; NativeMessagingHostInProcess – x64 project platform as I
was using 64 bit Windows and edge running as a 64 bit process as
well; Left rest as default.
With Debug Configuration and Any CPU Solution platform built the entire solution.
Deployment Summary
Built Entire SecureInput solution.
Installed AppX package by running
Add-AppxPackage -register [PathtoSecureInputSolutionFolder] NativeMessagingHostInProcess\bin\x64\Debug\AppxManifest.xml
No errors during building or while running Add-AppXPackage from elevated Power shell prompt.
Expected: At this point EdgeBrowser->MoreOptions->Extensions should list extension installed by AppX package (Deployment Summary/Step 2). =>> Doesn’t happen.
Few other details
I am using 64 bit Win 10 creators build (1703 – OS build 16063.128)
I am suspecting Add-AppxPackage failed to add the extension silently. Verbose flag doesn’t give me any clues either.
Get-AppXPackage shows newly added AppX package.

I would like to know if anyone got this sample working. If Microsoft Edge folks are monitoring stackoverflow, I really appreciate if someone can jump in to help your early adopters like me. :-)
With offline help from Chee Chen, we were able to figure out why SecureInput was not working. My sincere thanks to him for going out of his way to help. In my specific case, here are the things that went wrong.
URL manifest.json gives permissions to is case sensitive. I had a typo when I first entered the URL in edge browser very first time.. I typed in as SecureInput.html. Try cleaning the cache if you see that using lower case secureinput.html doesn't help.
When instructions didn't work right first time, I used Add-AppxPackage way of deploying the Extension. While doing that, I picked AppxManifest file in NativeMessagingHostInProcess\bin\x64\Debug\AppxManifest.xml instead of NativeMessagingHostInProcess\bin\x64\Debug\AppX\AppxManifest.xml. Something to watch out for and if you make the same mistake, make sure you uninstall the appx package completely and start all over again.
So here are my supplemental instructions for others trying the sample :-)
Make sure you selected right Platform as per your target test machine. Edge runs as 64 bit process so your extension needs to be targeted at that platform.
Make sure right AppServiceName is selected in PasswordInputProtection->Program.cs and Extension->background.js
I think PasswordInputProtection.csproj has a hardcoded Program files (x86) in its path, which will break if you try the sample on 32 bit machine. Edit the project file in notepad and fix it before you try.
Ensure NativeMessagingHost project's Output paths are correctly configured... It needs to be "bin\[Platform]\[Configuration]\AppX\" and not "bin\[Platform]\[Configuration]\"
Avoid typos if you can, because I see very little feedback or verbose logs on why things are not working.
Have you tried following the deployment steps in the documentation? The actual steps and ordering is important:
Build and deploy the NativeMessagingHostinProcess UWP app.
This will generate:
Necessary binaries and files needed for the UWP app.
The AppX folder.
The AppXManifest.xml based on the content of package.manifest. (The content of package.manifest in this sample has been edited to include the necessary entries for Edge extensions).
Build the PasswordInputProtection Desktop Bridge.
This will:
Build the binaries for this project
Trigger a post-build event that will copy the output of the exe to the AppX folder and copy the Extension folder to the AppX folder.
Now that the files are all ready to go, you will need to register the AppX.
There are two ways to accomplish this:
Run Add-AppxPackage from PowerShell: Add-AppxPackage -register [Path to AppX folder]\AppxManifest.xml
OR
Deploy the NativeMessagingHostInProcess project. Visual Studio will run the same PowerShell script to register the AppX from the folder.

Deploy WPF Project to UAT and Prod Environment

I am trying to enable the software tester to install 2 versions of the same application (one UAT and the other Production) on the same computer. I am using Visual Studio 2013 and the exe(installer) is created using ClickOnce. I was able to publish 2 versions to a directory, however, when the tester would try to install the second version it would overwrite the previous version. I did some research and found out that I had to rename the assembly. However, if I rename the assembly , I get the following error
"A first chance exception of type 'System.Windows.Markup.XamlParseException' occurred in PresentationFramework.dll"
Inner Exception : Could not load file or assembly 'xxx, Culture=neutral' or one of its dependencies. The system cannot find the file specified.":"xxx, Culture=neutral"}
I have tried cleaning, rebuilding , changing the namespace and I have absolutely no idea where I am going wrong. Any assistance will be greatly appreciated!
