MSBuild offers a .NET API surface that allows you toevaluate andbuild MSBuild projects from an application. MSBuild is available as a set of NuGet packages that can provide the implementation of the MSBuild programming language to your application. But it's generally not enough to be able to loadsome MSBuild project: you want your application to be able to load the.csproj,.vbproj,.fsproj,.sqlproj,.ccproj and other project types that you can build in Visual Studio (or Visual Studio Build Tools) or with the .NET SDK. To do that, you need more than just MSBuild's assemblies--you must also have access to all of the SDKs and build logic that are imported into those projects.

That additional build logic is distributed with Visual Studio, with Visual Studio extensions, or as part of the .NET SDK. So to correctly load projects, you need to load them in the context of one of those MSBuild installations.

Loading MSBuild from Visual Studio also ensures that your application gets the same view of projects asMSBuild.exe,dotnet build, or Visual Studio, including bug fixes, feature additions, and performance improvements that may come from a newer MSBuild release.

MSBuild.Locator searches for the locally installed SDK based on the following priority:

1. DOTNET_ROOT
2. Current process path if MSBuild.Locator is called from dotnet.exe
3. DOTNET_HOST_PATH
4. DOTNET_MSBUILD_SDK_RESOLVER_CLI_DIR
5. PATH

Note that probing stops when the first dotnet executable is found among the listed variables.

Documentation describing the definition of these variables can be found here:.NET Environment Variables.

Documentation is located on the official Microsoft documentation site:Use Microsoft.Build.Locator.
