Source generator not working?

I am trying to setup a incremental source generator, and following a number of different tutorials/blogs. It was working then I changed something and it no longer works, even after reverting the changes. This is the source gen .csproj file 
<Project Sdk="Microsoft.NET.Sdk">

    <PropertyGroup>
        <TargetFramework>netstandard2.0</TargetFramework>
        <LangVersion>10.0</LangVersion>
        <Nullable>enable</Nullable>
        <ImplicitUsings>enable</ImplicitUsings>
    </PropertyGroup>

    <ItemGroup>
        <PackageReference Include="Microsoft.CodeAnalysis.CSharp.Workspaces"
                          Version="4.0.1"
                          PrivateAssets="all" />
    </ItemGroup>
</Project>
<Project Sdk="Microsoft.NET.Sdk">

    <PropertyGroup>
        <TargetFramework>netstandard2.0</TargetFramework>
        <LangVersion>10.0</LangVersion>
        <Nullable>enable</Nullable>
        <ImplicitUsings>enable</ImplicitUsings>
    </PropertyGroup>

    <ItemGroup>
        <PackageReference Include="Microsoft.CodeAnalysis.CSharp.Workspaces"
                          Version="4.0.1"
                          PrivateAssets="all" />
    </ItemGroup>
</Project>
And this is how I am referencing it. 
<ProjectReference Include="..\SourceGen\SouceGen.csproj" 
                          OutputItemType="Analyzer"
                          ReferenceOutputAssembly="false"/>
<ProjectReference Include="..\SourceGen\SouceGen.csproj" 
                          OutputItemType="Analyzer"
                          ReferenceOutputAssembly="false"/>
And the test generator. 
[Generator]
public class TestingGenerator : IIncrementalGenerator
{
    public void Initialize(IncrementalGeneratorInitializationContext context)
    {
        throw new Exception("Test Exception!");
    }
}
[Generator]
public class TestingGenerator : IIncrementalGenerator
{
    public void Initialize(IncrementalGeneratorInitializationContext context)
    {
        throw new Exception("Test Exception!");
    }
}
I rebuild after every change using dotnet build MyProject.sln --no-incremental. I except to see a warning in the logs saying that the source gen .csproj will not be included but I don't. Anything clear that I am doing wrong or how to debug?

It was working, rider just wasn't seeing it... And adding to the consume csproj made it see them consistently. 
<EmitCompilerGeneratedFiles>true</EmitCompilerGeneratedFiles>
        <CompilerGeneratedFilesOutputPath>$(BaseIntermediateOutputPath)\Generated</CompilerGeneratedFilesOutputPath>
<EmitCompilerGeneratedFiles>true</EmitCompilerGeneratedFiles>
        <CompilerGeneratedFilesOutputPath>$(BaseIntermediateOutputPath)\Generated</CompilerGeneratedFilesOutputPath>
