The .NET SDK 4.0 or 4.5 tools could not be found.

First, my situation was that I had a brand new laptop which I had installed Windows 10 on. Next I installed Visual Studio 2015 Community Edition, full install (including support for F#).


So when I tried to compile my F# projects, I got this error:

The type provider 'Microsoft.FSharp.Data.TypeProviders.DesignTime.DataProviders' reported an error: The .NET SDK 4.0 or 4.5 tools could not be found.

So I found these resources:

• https://github.com/Microsoft/visualfsharp/issues/753
• https://github.com/Microsoft/visualfsharp/issues/637
• https://github.com/Microsoft/visualfsharp/issues/637

The third one seems to be the one to read, it has several suggestions. I tried to do several of them, but what fixed it in the end for me was the suggestion in the very last post:

• Install Windows 8 SDK.

I first had a problem installing it, it rolled back while installing, so what I think worked was to just check "Windows SDK" and ".NET 4.5 SDK" in the list of components, leaving the rest unchecked. I also tried to re-register the vbscript dll as per this post (which you may also try if it won't install):

• http://stackoverflow.com/questions/19251176/error-code-2753-during-install

I also ran the script that was mentioned in the forum, just mentioning in case it may have been a part of the solution.


I also restarted my PC quite a few times.


 So what didn't work (or did not seem to):

• Install Windows 8.1 SDK
• Install Windows 10 SDK
