Microsoft.NET.Test.Sdk-GlobalPackageReference-BuildError

Demonstrates the error that occurs when adding Microsoft.NET.Test.Sdk as GlobalPackageReference instead of a direct PackageReference.

Issue microsoft/vstest#5116

Description

Using the package Microsoft.NET.Test.Sdk as GlobalPackageReference generates the following code:

// <auto-generated> This file has been auto generated. </auto-generated>
using System;
[Microsoft.VisualStudio.TestPlatform.TestSDKAutoGeneratedCode]
class AutoGeneratedProgram {static void Main(string[] args){}}

This breaks the build with this error:

CS0234	The type or namespace name 'TestPlatform' does not exist in the namespace 'Microsoft.VisualStudio' (are you missing an assembly reference?)	
Project1.Tests	
%UserProfile%\.nuget\packages\microsoft.net.test.sdk\17.10.0\build\netcoreapp3.1\Microsoft.NET.Test.Sdk.Program.cs	3	

Steps

1. clone the repo
2. build the Microsoft.NET.Test.Sdk-GlobalPackageReference-BuildError.sln
3. you will get the error
