Native TypeScript support in Visual Studio 2015 is not available for all project types by default. As far as I’m aware, it is only available for the ASP.NET Web Application project type.
Sometime, you may be working with TypeScript but would prefer to use a different project type, e.g. when you are working with CRM or SharePoint. To add native TypeScript support to a project type of your choice, add the following to the project file:
<Import Project="$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v$(VisualStudioVersion)\TypeScript\Microsoft.TypeScript.targets" />
Reload your project, go to the project’s properties in Visual Studio and you should now see the TypeScript Build tab.
