Visual Studio Extension: Build error VSSDK1043: "There was a prblem finding the extension with a VSIX identifier..."

Question

I am trying to debug my extensions and suddenly I cannot build it anymore.

Error 1 There was a problem finding the extension with a VSIX identifier of "1cdefdc6-1f5e-4027-9bb7-773248c65070". Illegal characters in path.

I have rolled back all changes I made and still the error occurs. I don't think that I have changed any configuration.

This is not a dupliacte of: VSIX package build failed without showing the reason (Visual Studio bug) I have already tried those suggestions.

If I disabled

Deploy VSIX content to experimental instance for debugging

it compiles, but I cannot debug it.

Changing the Product ID also works, but this means, that it can no longer update the existing product.

Answer 1

I was getting the same error message (this is how i ended up hear) and then after changing the name i got the following error

VSIX development error VSSDK1040: There was a problem enabling the extension with a VSIX

Stumbled on the solution found here

What he did was delete this folder C:\Users\<UserName>\AppData\Local\Microsoft\VisualStudio

So i did that, am going to have to re-install a handful of extensions now as i am getting errors from them but it did correct my issue.

maybe you can dig a little deeper into the folder to find just the needed items to remove or do what i did and just nuke the folder and pick up the pieces

EDIT: from comments you may be able to get away with just removing anything under 'C:\Users\\AppData\Local\Microsoft\VisualStudio' with the EXP extension
