Visual Studio 2022 New Project Exception

We have created our own Visual Studio Template extension. We have this working for many years, but in our upgrade to .NET 6 we have to make a few changes.

When trying to create a new project from our template, we get this exception: enter image description here

The error itself is not much helpfull. I tried to find ways to get more logging out of VS, the only option i found is the run DevEnv.exe with -Log. Which i did, it gave me more meaningless details about the error, still nothing i could work with.

In older versions of Visual Studio, you could use a 2nd instance and attach it to the other instance. This does not work anymore, i cannot get any information out of my attached process.

What other options do i have to figure out which file Visual Studio appears to be missing?

Solution

  • Try to attach the Visual Studio debugger to another instance and replicate the error. This way you may be able to get more insight as to what is wrong.

    It does work. I faced a similar issue recently and did just that. Be sure to have the "Just My Code" checkbox disabled in Debug -> Options. Otherwise the debugger will not report the exception.
