# Microsoft.Build.Runtime This package delivers a complete executable copy of MSBuild. Reference this package only if your application needs to load projects or execute in-process builds without requiring installation of MSBuild. Successfully evaluating projects using this package requires aggregating additional components (like the compilers) into an application directory. 🗒️ NOTE: if you are building an application that wants to use MSBuild to evaluate or build projects, you will generally not need this package. Instead, use [MSBuildLocator](https://aka.ms/msbuild/locator) to use a complete toolset provided by the .NET SDK or Visual Studio.
