VS2015 - The 'NuGetPackage' package did not load correctly

Question

Just opened up VS 2015 Enterprise RTM, opened up an existing working project, getting the following error:

---

Microsoft Visual Studio

Answer 1

After a completely clean install of Visual Studio Professional 2015 from the MSDN Website, I ran VS2015 as Administrator, opened up the Package Manager Console from Tools -> NuGet Package Manager... -> Package Manager Console and I received this error:

"Windows PowerShell updated your execution policy successfully, 
but the setting is overridden by a policy defined at a more 
specific scope. Due to the override, your shell will retain its 
current effective execution policy of Unrestricted. 
Type "Get-ExecutionPolicy -List" to view your execution policy 
settings. For more information please see "Get-Help Set-ExecutionPolicy"

By following the above steps to

1) Use Tools -> Extensions and Updates... to uninstall NuGet Package Manager for Visual Studio 2015.

2) Restart Visual Studio.

3) Use Tools -> Extensions and Updates... to re-install NuGet Package Manager for Visual Studio 2015.

4) Restart Visual Studio.

Now when I open up the Package Manager Console, Powershell loads correctly and every thing is good. Thanks so much for this!
