Thanks for the report @jchannon

[DustinCampbell]

I can imagine why this would fail. Essentially, the service in omnisharp-roslyn gathers up all of the text changes and sends them back to the editor host (in this case, C# for VS Code) to apply. However, in this case, there aren't any text changes, just a file rename. This is something we'll need to handle in omnisharp-roslyn.

[rchande]

This should be fixed as of #1805

[DustinCampbell]

Unless we've added code to tell VS Code to apply a file rename, I wouldn't expect this to be fixed.

[DustinCampbell]

@rchande : Please check the repro. This is about the Rename File code fix, which still does not work.

[rchande]

@DustinCampbell You're right, this is a different bug. Thanks for noticing :)

The error message it gives me in a toaster is

Unable to open 'INewName.cs': Unable to read file 'c:\Users\...\INewName.cs' 
(Error: Unable to resolve non-existing file 'c:\Users\...\INewName.cs').

It's a pretty weird error, since the INewName.cs indeed is supposed not to exist. It's the one that should be written.

I am having this exact same issue.

This is very strange. I decided I wanted to fix this issue, I started by reproducing with the current release version which I was able to do easily. Next I got the code running on my machine, however when I try to reproduce the bug it doesn't happen even if I do a prod build with the current release version v1.24.4 checked out. I'm not really sure how to properly debug the production version of the extension so idk what's going on.

I did see this error in the dev tools console.

this shows up a few seconds after vscode tries to open the file C.cs which is what the new file would have been called.
