Every time I open existing or creating a new Windows Presentation Foundation project I get this error:
Could not load file or assembly 'Microsoft.Windows.Design.Extensibility, Version = 4.0.0.0,
Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies.'
Cannot find file.
Tried to resolve using different guides or examples. But I am totally lost...
Hope you can help me!
Thanks, Big D!

I have a WPF application that reads a CSV file using CSVHelper which I installed using NuGet. Here's the project, system, etc version info.
Microsoft Windows 7 Professional Version 6.1.7601 Service Pack 1 Build
7601
Microsoft Visual Studio Community 2019 Version 16.4.5
NuGet Package Manager 5.4.0
WPF Project Target Framework: .NET Framework 4.7.2
CSVHelper Version: 15.0.5
CSV reader method is straightforward; read a file and put it in a list. Nothing fancy. I'll link the entire project at the bottom so you can download and try it out if you want.
When I run the executable made in either Release or Debug builds, they work fine. They read the file, put contents in a list, and display on a DataGrid just fine. As a next step, I created a standard Visual Studio Setup project, and created an msi installer, which I used to install the app in my PC.
When I run that executable (which is in my Program Files directory), however, the application throws an exception. Here's the exception message and Stack Trace.
Could not load file or assembly 'Microsoft.Bcl.AsyncInterfaces, Version=1.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51' or one of its dependencies. Reference assemblies should not be loaded for execution. They can only be loaded in the Reflection-only loader context. (Exception from HRESULT: 0x80131058)
at ReadCSVTest.MainWindow.ReadPeopleList(String path, List`1& people, String& msg)
at ReadCSVTest.MainWindow..ctor()
Since the error says couldn't load the assembly Microsoft.Bcl.AsyncInterfaces, I added that from NuGet and ran everything again, and I still get the error. What's the problem here? What does it mean that Reference assemblies should not be loaded for execution. They can only be loaded in the Reflection-only loader context.? And why do I only get this exception when I run the executable installed by the Setup project?
Please download the entire project from HERE.
Just so anyone runs into the same issue in the future; as Jones suggested in the comments, downgrading each of the two libraries to following versions fixed the issue for me.
CsvHelper ==> 12.3.2
And
Microsoft.Bcl.AsyncInterfaces ==> 1.0.0
I added the new "Windows Application Packaging Project" that comes with vs2017 15.4 preview.
When adding my project to the "Applications" and debugging the packaging project I have the following error:
System.IO.FileNotFoundException: 'Could not load file or assembly
'System.Runtime, Version=4.1.2.0, Culture=neutral,
PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The
system cannot find the file specified.'
InnerException: FileNotFoundException: Could not load file or assembly
'System.Runtime, Version=4.0.0.0, Culture=neutral,
PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The
system cannot find the file specified.
My project is running perfectly if I debug it directly or run it directly using the EXE.
If I extract the files from the .appxbundle and try to start the EXE, it doesn't work either. (XXXXXX.appxbundle\XXXXXX.appx\*.*)
I noticed that in the extracted .appxbundle folder, all System.XXX DLLs are not there. They should be (94 dlls are missing).
Is there a problem with the packaging tool ?
UPDATE:
Link to dev portal: https://developercommunity.visualstudio.com/content/problem/122252/windows-application-packaging-project-tool-failed.html
This is very likely a bug in the way the packaging project is collecting files. Looks like we're already tracking this bug in the Developer Community. Also, we're tracking another related issue for ClickOnce.
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)
I am developing my first project using WCF RIA services. I was able to build a small application and ran it successfuly on localhost. When tried to upload on a server, I got the following error when browsing it :
"Could not load file or assembly
'System.ServiceModel.DomainServices.Hosting, Version=4.0.0.0,
Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its
dependencies. The system cannot find the file specified"
I looked for this reference on my project and did not find it. I tried to add it from C:\Program Files (x86)\Microsoft SDKs\RIA Services\v1.0\Libraries\Server, but Visual Studio warns me:
You cant add a reference to
System.ServiceModel.DomainServices.Hosting.dll as it was not built
against the silverlight runtime.silverlight projects will only work
with silverlight assemblies
What should I do?
Thanks
Found the problem: on my .Web under references, found the needed dll.On properties, changed copy local to True
I am using the Microsoft.Build.BuildEngine to build a number of projects. Projects that do not use Silverlight are building correctly while projects that do use Silverlight are not building. All of these projects (Silverlight and non-Silverlight) all build fine through Visual Studio 2008. I get the error message:
error CS0234: The type or namespace name 'SilverlightControls' does not exist in the
namespace 'System.Web.UI' (are you missing an assembly reference?)
I've added System.Web.Silverlight to the project that is doing the build using Microsoft.Build.BuildEngine. I am able to see that namespace in the project doing the build also (so it appears that the project doing the build does have access to System.Web.UI).
Any ideas on how I can avoid that error?
Turned up the verbosity on the build through VS2008 and compared to the log created from the Microsoft.Build.BuildEngine. It looks like the Microsoft.Build.BuildEngine is producing lines like:
Considered "c:\Program Files\Reference Assemblies\Microsoft\Framework
\v3.5\System.Web.Silverlight.dll", but it didn't exist.
It doesn't exist in that location, should it? There are actually a number of locations that it looks for that dll and doesn't find it. I added the reference by right clicking, add reference, .Net, add. There doesn't appear to be a System.Web.Silverlight.dll on my machine (which is odd because the project does compile using VS2008).
Comparing the possibly relevant sections of the two logs:
Microsoft.Build.BuildEngine
For SearchPath "{GAC}".
Considered "System.Web.Silverlight, Version=2.0.5.0, Culture=neutral,
PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL", which was not found in
the GAC.
Visual Studio 2008
System.Web.Silverlight, Version=2.0.5.0, Culture=neutral,
PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL
Manually added System.Web.Silverlight to the path that the Microsoft.Build.BuildEngine was looking for it (coppied it from the output directory when I build the project via VS2008). This solved that problem, but I now get the following errors on the Silverlight components of the solution:
C:\Program Files\MSBuild\Microsoft\Silverlight
\v2.0\Microsoft.Silverlight.Common.targets(95,9): error : The Silverlight 2 SDK is not
installed.
Any ideas?
In the application that is running the Microsoft.Build.BuildEngine I changed the type of build from Any CPU to x86. This has now made the application be able to build the target as expected.
So you're programmatically building using the MSBuild APIs?
It may be useful to add an ILogger (e.g. that just prints to the console) to engine.Loggers, and compare the output with the output window in VS (after setting e.g. 'tools\options\project & solutions\build & run\msbuild output verbosity' to verbose)... seems like somehow the environment is causing assemblies to resolve differently?
Set build type of project to Any. This helps. Happy coding...
