MSBuild is now available as part of the .NET Core SDK and can build .NET Core projects on Windows, macOS, and Linux.
MSBuild is now installed in a folder under each version of Visual Studio. For example,
C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\MSBuild. You can also use the following PowerShell module to locate MSBuild: vssetup.powershell.
MSBuild is no longer installed in the Global Assembly Cache. To reference MSBuild programmatically, use NuGet packages.
The following MSBuild properties have been updated due to the new version number.
MSBuildToolsVersionfor this version of the tools is 15.0. The assembly version is 188.8.131.52.
MSBuildToolsPathno longer has a fixed location. By default, it is located in the MSBuild\15.0\Bin folder relative to the Visual Studio installation location, but the Visual Studio installation location can be changed at install time.
ToolsVersionvalues are no longer set in the registry.
SDK40ToolsPathproperties point to the .NET Framework SDK that's packaged with this version of Visual Studio (for example, 10.0A for the 4.X tools).
