Why is dotnet build not using the specified SDK on global.json?

Question

I have a global.json with the following contents

{
  "sdk": {
    "version": "2.2.300"
  }
}

This is the output of dotnet --list-sdks

2.0.3 [C:\Program Files\dotnet\sdk]
2.1.105 [C:\Program Files\dotnet\sdk]
2.1.300 [C:\Program Files\dotnet\sdk]
2.2.300 [C:\Program Files\dotnet\sdk]

This is the output of donet --list-runtimes

Microsoft.AspNetCore.All 2.1.0 [C:\Program Files\dotnet\shared\Microsoft.AspNetCore.All]
Microsoft.AspNetCore.All 2.2.5 [C:\Program Files\dotnet\shared\Microsoft.AspNetCore.All]
Microsoft.AspNetCore.App 2.1.0 [C:\Program Files\dotnet\shared\Microsoft.AspNetCore.App]
Microsoft.AspNetCore.App 2.2.5 [C:\Program Files\dotnet\shared\Microsoft.AspNetCore.App]
Microsoft.NETCore.App 2.0.3 [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
Microsoft.NETCore.App 2.0.7 [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
Microsoft.NETCore.App 2.1.0 [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
Microsoft.NETCore.App 2.2.5 [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]

Yet when I do dotnet build I get the following error

Microsoft (R) Build Engine version 16.1.76+g14b0a930a7 for .NET Core Copyright (C) Microsoft Corporation. All rights reserved.

C:\Program Files\dotnet\sdk\2.1.300\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.TargetFrameworkInference.targets(137,5): error : The current .NET SDK does not support targeting .NET Core 2.2.

Build FAILED.

I need help, this is driving me nuts

Answer 1

Ok, found the solution, it seems this Environment System Variable

MSBuildSDKsPath was pointing to the .NET Core 2.1.300 Sdks folder, removing that variable addressed the problem.
