Previous changes from v16.0.461.62831

  • MSBuild 16.0

    This version of MSBuild shipped with Visual Studio 2019 version 16.0.

    What's new

    🚀 Highlights of this release are:

    • 🏗 MSBuildToolsVersion is now Current. Choose the version of tools and build logic you wish to use by selecting from different MSBuild instances, rather than specifying ToolsVersion.
    • MSBuild now targets .NET 4.7.2.
    • 🏗 MSBuild now has options to treat a build as a directed acyclic graph of projects. This is an experimental feature. Its public interface may change before it is stabilized.
