Configuration system failed to initialize

Question

_{Wednesday, April 11, 2018 5:17 AM}

Hi

A vb.net winform solution builds fine in debug configuration. When running the app I get exception below at the end. In the background I also get this;

Locating source for 'f:\dd\ndp\clr\src\BCL\system\threading\thread.cs'. (No checksum.)
The file 'f:\dd\ndp\clr\src\BCL\system\threading\thread.cs' does not exist.
Looking in script documents for 'f:\dd\ndp\clr\src\BCL\system\threading\thread.cs'...
Looking in the projects for 'f:\dd\ndp\clr\src\BCL\system\threading\thread.cs'.
The file was not found in a project.
Looking in directory 'c:\Program Files\Microsoft Visual Studio 10.0\VC\crt\src\'...
Looking in directory 'c:\Program Files\Microsoft Visual Studio 10.0\VC\atlmfc\src\mfc\'...
Looking in directory 'c:\Program Files\Microsoft Visual Studio 10.0\VC\atlmfc\src\atl\'...
Looking in directory 'c:\Program Files\Microsoft Visual Studio 10.0\VC\atlmfc\include\'...
The debug source files settings for the active solution indicate that the debugger will not ask the user to find the file: f:\dd\ndp\clr\src\BCL\system\threading\thread.cs.
The debugger could not locate the source file 'f:\dd\ndp\clr\src\BCL\system\threading\thread.cs'.

How can I fix this please and get the app running?

Thanks

Regards

Hi Y a h y a，

What about this issue in your side?

Could you enable the Exception settings window, and then debug your app again?

Whether your app refer to certain dll/third party dll files which has no the source code in your side?

Best Regards,

Jack
