Yesterday I have installed my VS2010 RC, but did not work when I try to set F# as default settings, and try to open a new project [any project unfortunately]
The error message is :
“The project file ‘C:\Users\Ebru\AppData\Local\Temp\qxdqjrxq.oco\Temp\Library1.fsproj’ cannot be opened. because its project type (.fsproj) is not supported by this version of the application.
To open it, please use a version that supports this type of project.”
here is my screenshot…
How dissapointing is that I have to install R# Runtime separately…And to fix this you may re-run this exe and repair it.
Then, you may start your F# project.
And
continuous learning ...
