"Failed to retrieve msbuild property ProjectGuid form the project file" error

[vasily-kirichenko]

1. Open any file from FSharp.Editor - OK
2. Open service.fs from FSharp.LanguageService.Compiler:

3. Close it, reopen. Same error.

Is this on RC3 + VSIX or latest master?

[vasily-kirichenko]

RC3 + VSIX.

[cartermp]

Hmm. I can't repro this on my machine, although for some reason I'm also unable to load certain projects because it thinks I need the ASP.NET workload. Creating issue...

[cartermp]

So to clarify, I'm unable to build: FSharp.LanguageService.Base, ProjectSystem.Base, FSharp.PropertiesPages

Which aren't F# so it makes be believe that there's a setup issue on my machine. That said, I still can't repro your issue:

I have just encountered this issue. RC3 + VSIX. Screenshot and VS version details below.

Can I help figure it out? It's basically a brand new project, although I don't recall if I created pre or post VSIX install.

@bentayloruk I think it makes no sense to test RC3 anymore.

[bentayloruk]

Ah, OK. How come? Is there a later VSIX or is it build your own time?

[vasily-kirichenko]

Just update VS, it's now RC4, no need for manually installed VSIX

[bentayloruk]

Doh! Thanks. 😊

[cartermp]

I actually noticed this on RC4 + Parallels + the Nu project yesterday. I'm not sure if it was just some pain related to using a project not built in VS2017 or not, but based on the above it does sound like there's a bug somewhere.

[BentTranberg]

I got this error dialog when trying to open fs files in any kind of F# project in a solution with the fresh release version of VS 2017. The files opened in spite of the error dialog. .NET Framework 4.5.2, F# 4.0 (4.4.0.0).

After restarting VS the problem disappeared, but another problem with missing or superfluous entries in the Error List pane appeared instead. Not sure if it's related.

[cartermp]

@BentTranberg Could you create a separate issue about the superfluous entries? If you have a minimized repro + screenshots that would be superb.

[BentTranberg]

I did, but I doubt it's related. Here: https://github.com/Microsoft/visualfsharp/issues/2548
