Tobias Knauss enhanced developer documentation for MSBuild across the MicrosoftDocs/visualstudio-docs and dotnet/docs repositories, focusing on clarifying property semantics and improving onboarding materials. He corrected the TreatWarningsAsErrors documentation to accurately distinguish it from the '/nowarn' compiler switch, ensuring developers use the correct property. Tobias also added missing guidance for the FrameworkReference property, addressing gaps in the msbuild-props.md file. His work involved precise technical writing and effective cross-repository collaboration, using Markdown and version-controlled workflows. These targeted improvements reduced developer friction, aligned documentation with SDK behavior, and contributed to more efficient support and onboarding for teams working with MSBuild.
