Enabling Code Generation

To use the code generation for your custom classes (it’s already enabled for engine classes), update your project file (csproj) to include the source generator. Add the following lines to your csproj file:

<ItemGroup>
    <Analyzer Include="..\..\Plugins\UnrealSharp\Binaries\Managed\netstandard2.0\UnrealSharp.ExtensionSourceGenerators.dll" />
</ItemGroup>
