After upgrade VS2022 to Preview 4.1 from 3.1, my project throw StackOverflowException (after fix lots of reference error)
System.StackOverflowException
  HResult=0x800703E9
  Message=Exception of type 'System.StackOverflowException' was thrown.

Stack overflow.

I know post to MS's developer forum is useless, and VS2022 can't downgrade now, so the only way is try and error by myself.

Turn out, the stackoverflow exception cause by Microsoft.Extensions.Configuration from this code:
builder.Services.AddSingleton<IConfiguration>(builder.Configuration);
After more dig-in, I found the framework already called this on Hosting , so maybe the duplicate call cause the stackoverflow exception, but still not sure why it worked on VS2022 preview 3.1, not work on preview 4.1.

Solution


Remove the line
services.AddSingleton<IConfiguration>(configuration);
(or similar) on your Program.cs
