including-generated-files

To include generated files in MSBuild compilation, explicitly add them to the Compile and FileWrites item groups within the appropriate build targets so the build system tracks and compiles them correctly.

dotnet build misses generated source files because default glob patterns do not automatically track files created in intermediate output paths during the build process, requiring explicit inclusion in the Compile item group.

To clean up generated files during incremental builds, add the generated files to the FileWrites item group so MSBuild can track them for proper deletion and ensure correct output during subsequent builds.

You need to explicitly track generated files in MSBuild when a custom tool generates C# code during the build process, ensuring the generated code is compiled and available in the final output.

The best way to ensure generated code is compiled during dotnet build is to explicitly include the generated source files in the Compile and FileWrites item groups within your custom MSBuild targets.
