Overview

This repository serves as a minimal reproduction for a bug I found with Source Generators.

Steps

• Install .NET 7 (tested with 7.0.306)
• Run dotnet build in the src folder
• In src\TestGenerator\TestGenerator.cs change the type name from TestGenerator1 to TestGenerator2
• Run dotnet clean in the src folder (otherwise the build does not re-run)
• Run dotnet build in the src folder

Expected result

Actual result

[<localPath>\src\TestGenerator.Tests\TestGenerator.Tests.csproj]
