MSBuilder.VsixInstaller (nuget): On a project that references the Microsoft.VSSDK.BuildTools  package, enables installing extra VSIXes to the targetted Visual Studio  version and instance by simply declaring them as @(Vsix) items:  <ItemGroup>   <Vsix Include="MyOtherExtension.vsix" /> </ItemGroup>  The items will be installed only if needed so that incremental  builds are fast, and only if the current project's $(DeployExtension)  is set to 'true'.  The installation happens automatically before the DeployVsixExtensionFiles  runs, but can also be manually invoked by running the InstallVsix target.
