Error NU1202 installing tool in .NET 5 project

See original GitHub issue

Hello! I believe this is a typo issue somewhere in the prerelease.

What are you seeing?

I tried to install the Cake tool in a .NET 5 project (with <TargetFramework>net5.0</TargetFramework>) and I get this error:

error NU1202: Package Cake.Tool 1.0.0-rc0001 is not compatible with net50 (.NETFramework,Version=v5.0) / any. Package Cake.Tool 1.0.0-rc0001 supports:
error NU1202:   - net5.0 (.NETCoreApp,Version=v5.0) / any
error NU1202:   - netcoreapp2.1 (.NETCoreApp,Version=v2.1) / any
error NU1202:   - netcoreapp3.0 (.NETCoreApp,Version=v3.0) / any
The tool package could not be restored.
Tool 'cake.tool' failed to install. This failure may have been caused by:

* You are attempting to install a preview release and did not use the --version option to specify the version.
* A package by this name was found, but it was not a .NET tool.
* The required NuGet feed cannot be accessed, perhaps because of an Internet connection problem.
* You mistyped the name of the tool.

What is expected?

The Cake tool should be installed correctly.

What version of Cake are you using?

Prerelease 1.0.0-rc0001.

Are you running on a 32 or 64 bit system?

64 bit

What environment are you running on? Windows? Linux? Mac?

Windows

Are you running on a CI Server? If so, which one?

No, this is just a local project

How did you get this to happen? (Steps to reproduce)

This is reproducible in a very simple way, at least on my machine. With the latest .NET 5 SDK installed, run:

dotnet new console -o TestThing
cd .\TestThing\
dotnet new tool-manifest
dotnet tool install Cake.Tool --version 1.0.0-rc0001

And you get the error.

Output Log

None!

I just found out! It’s an environment variable issue. I set MSBuildSDKsPath to C:\Program Files\dotnet\sdk\5.0.100\Sdks and everything went back to working normally. It’s always a pain switching .NET versions, hm…

Could be a NuGet cache being corrupt issue

Try dotnet nuget locals all --clear
