Visual Studio 2019: Source information is missing from the debug information for this module

Question

I am using Visual Studio 2019. The Program was executing fine. I made a few harmless code changes and now suddenly the program does not run at all. When I execute, it displays the error message in the picture below.

This is what the solutions explorer property tab looks like

Any thoughts on what I can do to fix this problem?

Hi @Elba

Welcome to Microsoft Q&A!

Please confirm that the references your application depends on have not been deleted.
You can try the following methods:

1). TOOLS->Options->Debugging->General, disable "Require source files to exactly match the original version" .
2). TOOLS->Options->Debugging->Symbols, enable the Microsoft Symbols Server.
3). TOOLS->Options->Debugging, check "Enable Just My Code' and "use Manage/Unmanage mode".

Clear the solutions generated by the last build, then rebuild your app.

We look forward to hearing from you.

Sincerely,
Peng
