Setting Compiler Options in MSBuild projects

Overview

Compiler options can be specified using MSBuild properties within an MSBuild project.

Example

  <PropertyGroup Condition="'$(Configuration)' == 'Debug'">
    <TypeScriptRemoveComments>false</TypeScriptRemoveComments>
    <TypeScriptSourceMap>true</TypeScriptSourceMap>
  </PropertyGroup>
  <PropertyGroup Condition="'$(Configuration)' == 'Release'">
    <TypeScriptRemoveComments>true</TypeScriptRemoveComments>
    <TypeScriptSourceMap>false</TypeScriptSourceMap>
  </PropertyGroup>
  <Import Project="$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v$(VisualStudioVersion)\TypeScript\Microsoft.TypeScript.targets" Condition="Exists('$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v$(VisualStudioVersion)\TypeScript\Microsoft.TypeScript.targets')" />

¹ These settings are new in TypeScript 1.8

What is supported in my version of Visual Studio?

Look in your C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v$(VisualStudioVersion)\TypeScript\Microsoft.TypeScript.targets file. The authoritative mappings between MSBuild XML tags and tsc compiler options live in there.

ToolsVersion

The value of <TypeScriptToolsVersion>1.7</TypeScriptToolsVersion> property in the project file identifies the compiler version to use to build (1.7 in this example). This allows a project to build against the save versions of the compiler on different machines.

If TypeScriptToolsVersion is not specified, the latest compiler version installed on the machine will be used to build.

Users using newer versions of TS, will see a prompt to upgrade their project on first load.
