I need to generate Source Maps when the TypeScript Compiler is executed from Visual Studio 2012. In Sublime Text 2, I just had to add an extra parameter to the build script. I'm lost in VS 2012. The Build section doesn't seem to have a section to add build parameters to the build process.
The command switch is "-sourcemap".
As such: tsc -sourcemap file.ts
Mads Kristensen's Web Essentials extension for Visual Studio added support for producing source maps automatically in version 1.3. You need to enable it in in Tools -> Options for Web Essentials. http://visualstudiogallery.msdn.microsoft.com/07d54d12-7133-4e15-becb-6f451ea3bea6
The free Express editions of Visual Studio does not support extensions.
There isn't a VS 2012 UI for editing the TypeScript build flags (yet) but you can get what you want by editing the project file and adding the -sourcemap flag to that build step.
<Target Name="BeforeBuild">
<Exec Command=""$(PROGRAMFILES)\Microsoft SDKs\TypeScript\0.8.0.0\tsc" -sourcemap @(TypeScriptCompile ->'"%(fullpath)"', ' ')" />
</Target>
