The current .NET SDK does not support targeting .NET Core 3.0 | 3.1 | 5.0 | 6.0

Question

I've just downloaded the release version of .NET Core 3.0.100
It was installed alongside older version that I have:

When I try to run dotnet restore for a project that targets .NET Core 3 (<TargetFramework>netcoreapp3.0</TargetFramework>), I get this error

C:\Program Files\dotnet\sdk\2.2.202\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.TargetFrameworkInference.targets(137,5): error NETSDK1045: The current .NET SDK does not support targeting .NET Core 3.0.  Either target .NET Core 2.2 or lower, or use a version of the .NET SDK that supports .NET Core 3.0. 

I have a global.json file that explicitly states that I need the 3.0.100 SDK

{   "sdk": {     "version": "3.0.100"   } } 

I know that I can edit the MSBuildSDKsPath env variable to point to the 3.0.100 SDK, and it works, but I don't want to do it, I have other projects on my machine that still need to use older versions of .NET Core.

Is there a way to make the dotnet tool use the SDK that's stated in global.json instead of the one in MSBuildSDKsPath?

Edit: I use Visual Studio Code

You also have to update your visual studio to the minimum supported version:

.NET Core 3.0

• minimum visual studio v16.3

.NET Core 3.1

• minimum visual studio v16.5

.NET Core 5.0

• minimum visual studio v16.6 latest preview

.NET Core 6.0

• minimum visual studio v17.0 latest preview
