Fable: Cannot reference Fable.Core.dll with VS2015 Community

[MangelMaxime]

When trying to reference Fable.Core.dll I got this error;

Even, if we try using Project Reference we don't access to Fable namespace.

Is there a possibility that the file is correct?
If you create a new project and install the npm packages, do you get the same error?

[MangelMaxime]

This is a new project :)

Actually, @alfonsogarciacaro mentions that he got the same error with VS17 under OSX.

[alfonsogarciacaro]

Not exactly the same, I get the following in VS for Mac, but I can actually use the assembly without problems: I have intellisense, etc. Using Mono.

[MangelMaxime]

Ah ok...
But perhaps they are related.

Ok. I opened it in VS2017 without any issue but that is on windows. The F# experience is terrible compared to VS2015 but that is a different story. If the issue still persists, perhaps you can upload the solution somewhere and I can confirm if the same issue exists on windows.

I'm on Windows now. I downloaded fable-core 0.7.9, created a new F# project with VS 2015 Community, added a reference to Fable.Core.dll and didn't have any problem (I could access types in the namespace normally), so I'm not sure what could be going wrong in your case :/

[MangelMaxime]

Ok...
Perhaps I have a problem with my computer setup...
I will try on Monday to reinstall all my dev env.

Thanks for the help

@MangelMaxime Could you please confirm if you're still having the issue? I've found that sometimes there're problems in Windows with references if .NET 4.5 SDK (Windows 8) is not installed.

@alfonsogarciacaro Sorry, I forget to comment again.
No I don't have anymore this issue you can close it I think.

I got this error again and was able to sovle it.

Step to fix:

1. In VisualStudio, force the solution/project to be cleaned.
2. Try to add the DLL. It's should be ok

If ever this is not OK after the clean up, make sure to have an ouput configure for the project.

Interesting, thanks a lot for sharing the solution. Hopefully it will help users with the same problem :+1:
