I am looking for information how IsolatedStorage.ApplicationSettings are affected by Assembly Version. Is there a way to specify version to get same ApplicationSettings for any version of same app?
According to Microsoft, the ApplicationSettings are per xap path, not assembly version:
Their scope is determined by the full path of the application .xap file
Checkout this MSDN article for more info.
Sounds like support for multiple browsers is known to be flaky.
You will also find that running your app in the Visual Studio dev server will have unexpected results if/when the port changes.

detailed message box texti made a winform application on my pc and it runs fine. but when I tried to run it on another PC by copying the exe file and other dll files there , the application failed to run and all of a sudden it shows a dialog box to close the aplication.
please refer to screenshot of error.

Like bassfader said: One possible explanation is that your application is handling files during startup. In that case: integrate more extensive exception handling for those parts. Potentially with logging, to locate the problem
In my experience this however is more often a case of missing some kind of dependency.
Double check .NET runtimes. Lookup the target .net version in Visual Studio and run the installer on the target machine.
Investigate if your app uses any assemblies that are not part of the .NET framework. Sometimes these are not copied to the bin directory if they are in the GAC (ensure the flag "Copy Local" is set to "Always" in Visual Studio)
Ensure you have copied the whole bin folder
Check compiler output to see if you've got Platform mismatches. IIRC this can sometimes work fine on a dev machine but cause problems when Visual Studio is missing or you get to a different OS.
I am using a variation of Jeff Atwood’s Unhandled Exception handler it steps in when there is an Unhandled Exception in the application. It then logs the error, generates a screen shot and notifies the user.
When compiled in a solution the project generates an EXE that is called when needed. In updating the program I am using Visual Studio 13 to edit the existing settings items in the project properties. In the code I use commands such as this from ConfigurationManager.
string appProduct = unhandledExceptions.Properties.Settings.Default.AppProduct;
I was happy to see that it worked and reflected the changes I made in the IDE. However I couldn’t find the settings in the solutions generated confg file (MyApplication.exe.config). I assumed it was reaching back to the other project folder for the UnhandledExceptions.exe.config.
I created an installer and installed it to a virtual machine. My settings carried over, but again I could not see a config file.
It turns out the values are embedded in the executable UnhandledException.exe.
The project does not have any resources listed. Searching the web and StackOverflow looking a questions that want to do this, and there are a lot of them, it seems this was generally considered not possible and not desirable. Questions usually end in “You don’t want to do that, it’s called config for a reason”.
I may want to turn this off, so it is editable externally. The properties of app.config in both projects are identical.
What setting is making this possible after all? Is it a new capability with Visual Studio 2013?
There is no Visual Studio setting required. If you don’t want the user to have access to the configuration file, don’t include it in the distribution. One can always be added if the settings names are known.
In the description below application generically represents the name of the application being used.
I’ve found through observation some interesting things about the way ConfigurationManager works.
For User settings it will look in the following places in order of priority:
user.config for the application in the user’s AppData area
application.exe.config in the program folder
application.exe itself
Each setting is searched for individually. If your application requests a setting that is not found in either user.config or the application.exe.config it will get it from the executable.
For Application settings it looks in the following places in order of priority:
application.exe.config in the program folder
application.exe itself.
There is no equivalent to user.config for application settings.
Opening the application.exe in the Visual Studio IDE does not reveal a resource for the configuration information.
application.exe.config is handy because it can be modified externally and used as a default value for new installations. Once a setting is overridden in the user.config the value in application.exe.config is ignored.
The same is not true for the AppSettings section, the older configuration method from .Net 1.0. If I delete the configuration file it does not have them in the executable.
These observations were made with Visual Studio 2013 Update 4 and tested in Windows 7 Professional 64-bit. I suspect they are true in all versions.
'Hi all, I downloaded Xilium.CefGlue and built the source on Visual Studio (xilium-xilium.cefglue-b22787699e57), I also downloaded cef_binary_3.1453.1236_windows_xilium and copied the libcef.dll to the Xilium Winforms demo as the apps requires it to run but when I run it I get the following error:
An attempt was made to load a program with an incorrect format.
Exception from HRESULT: 0x8007000B
I've targeted x86, can I get some help?
Thanks
Ok, here's the steps I used to get the samples working in VS 2012:
Get the code from Xilium.CefGlue on github. (The one I used was c3d674a3a8)
Open the Xilium.CefGlue solution in VS2012
Remove or don't build the CefGlue.Demo.GtkSharp project (it didn't interest me & I didn't have the needed libraries)
In the Configuration Manager, select Active Solution Platform to be x86
Ensure that the target framework settings cooperate between projects. (e.g. CefGlue.Demo & CefGlue.Demo.WinForms by default are v2.0, but they depend on CefGlue which is v4.5) (For simplicity I set them all to v4.0 Client profile and it worked.)
Build solution — should succeed
Copy Xilium files from the unzipped cef_binary_3.1453.1236_windows_xilium to the output folder (bin\x86\Debug or bin\x86\Release). Minimum requirement seems to be:
libcef.dll and icudt.dll from .\Debug or .\Release
cef.pak and the locales\ folder from .out\Debug or .\Resources
Set CefGlue.Client as the StartUp Project
Run it
I recently inherited a C# Winforms application that communicates with Quickbooks via their QBFC interface. The application contains a reference to the COM Server Interop.QBFC7.dll. The application works fine in our test environment and in several of our client's environments. Although, yesterday when I attempted to install it on a new customer's system I continued to get the following error:
Could Not Load File or Assembly 'Interop.QBFC, Version=8.0.0.87, Culture=neutral, PublicKeyToken=...' or one of its dependencies. The system cannot find the file specified.
I know that we have several customers running this application on various versions of Quickbooks (i.e. Quickbooks Pro, Premier and Enterprise between 2008 and Enterprise 11.0). To my knowledge, this is the first customer that we have attempted to deploy this application that has Enterprise 12.0.
I have attempted the following to resolve the issue with no success:
1) Install the QBFC7_Installer from the Intuit Developer Network Site
2) Install the Quickbooks SDK 10 Installer from the Intuit Developer Network Site
3) Verified that the Interop.QBFC7.dll file is present on the file system.
4) Attempted to manually register the COM object Interop.QBFC7.dll via the command prompt: regsvr32 Interop.QBFC7.dll (This fails as well and windows returns an error stating that it cannot find the object).
Does anyone have any suggestions or feedback about additional things that I can try to resolve this issue? I get the same error on 3 different machines at their site running different operating systems (i.e. Windows Server 2008, Windows 7, and Windows Vista)? I have also tried compiling in both x86 and 64-bit configurations to no avail.
Thanks in advance for any help.
First of all, you should be targeting an x86 build only. The QuickBooks SDK won't work if you target Any CPU or x64. Your main problem, though, is that you are looking for the wrong version of QBFC. Notice the version stamp on your error message:
Could Not Load File or Assembly 'Interop.QBFC, Version=8.0.0.87,
Culture=neutral, PublicKeyToken=...' or one of its dependencies. The
system cannot find the file specified
This is QBFC8, not QBFC7. So you should be able to fix the problem with the QBFC8 installer.
The version of QuickBooks should not make a difference, since QBFC 8 (or 7, for that matter) will work with the 2008 and Enterprise 11 or 12.
You should look into using a setup project to install your application in order to avoid this problem in the future. A setup project should detect the QBFC dependency automatically. Once you see this happening, go to SearchPath property of your setup project and add the MergeModule directory from the SDK that is installed on your machine. Once you do this, you should see that the QBFC and Xerces merge modules are added to your project automatically as dependencies. Of course, you'll also need to update your code to a more recent version of QBFC, but that's probably a good idea in any case.
So I enabled this group policy and the first time I tried to compile my solution I get this error. The funny thing is that I only use cryptographic function in one place but what I am seeing this on is all my Silverlight ResourceDictionary files and WPF userControl files. Everything else seems to compile fine.
Why am I seeing the error on only xaml files where I do nothing with encryption? I know I can disable the FIPS group policy but I do want to support it. Any idea why specific XAML files are throwing this error during compile?
I know I'm a bit late to the game but I recently came across this problem and also figured out a solution. For the reasons stated by #mdutra above, this is why it doesn't work but interestingly, Visual Studio 2010 and 2012 have two different "fixes".
A Microsoft Connect post (that no longer exists) stated:
Visual Studio 2012 now builds C# projects in a separate process that runs msbuild. The entry you added to devenv.exe.config (that worked for VS 2010) won't be seen by this process. You should add <enforceFIPSPolicy enabled="false"/> directly above the </runtime> tag in the msbuild.exe.config file; typically found at C:\Windows\Microsoft.Net\Framework\v4.0.30319\msbuild.exe.config.
I also added it to the C:\Windows\Microsoft.Net\Framework64\v4.0.30319\msbuild.exe.config file as well since I didn't know which MSBuild I was using.
After some research I found this answer which makes sense:
WPF and FIPS
Here are the contents of the link just in case it is removed:
The following is the reply I got from the WPF XAML team:
We didn’t fix it because this issue was discovered days (June 2, 2008) before the release.
I still have the BBPack I didn’t checkin. Here is the comment from the code.
// The Federal Information Processing Standard mandates that
// MD5 is obsolete and not safe for cryptographic checksums.
// We are using it to coordinating source files for debugging
// not authenticating so MD5 use is OK here.
// But, on a OS with the FIPS compliant switch ON, the managed
// MD5CryptoServiceProvider Ctor will throw. So we can't use it.
//
// Currently we use a PInvoke wrapper to the Native layer;
// which still works, even on a FIPS compliant machine. A Better
// fix would be to move to the approved SHA checksums, but that
// will require co-ordination with VS and the Debugger groups etc.
The MSI builder and a few other tools also threw on a FIPS=1 machine.
So even we if we fixed our part (in 3.5sp1), the customer’s end-to-end solution was still broken.
