The above code works find in TypeScript Play, but I received build error
when compiling it from Visual Studio 2012 error "exited with code 1"

You’ll need to target ECMAScript v5, ie pass the -target ES5 argument to the compiler. This needs to be set in the project files target configuration.

I don’t know if VS has any built in mechanims for editing target configurations, so i can only tell you how to do it manually. Simply open your .csproj project file, look for the Target node where the TypeScript compiler command is located, and add the -target ES5 argument.

In my config it looks like this:

<Target Name="BeforeBuild">
    <Exec Command="&quot;$(PROGRAMFILES)\Microsoft SDKs\TypeScript\0.8.0.0\tsc&quot; -target ES5 @(TypeScriptCompile ->'&quot;%(fullpath)&quot;', ' ')" />
</Target>

Update

As of version 0.8.1.0, the hardcoded version dependency was removed and support for source maps was added, and so the Target node now looks like this by default:

<Target Name="BeforeBuild">
    <Message Text="Compiling TypeScript files" />
    <Message Text="Executing tsc$(TypeScriptSourceMap) @(TypeScriptCompile ->'&quot;%(fullpath)&quot;', ' ')" />
    <Exec Command="tsc$(TypeScriptSourceMap) @(TypeScriptCompile ->'&quot;%(fullpath)&quot;', ' ')" />
</Target>

Injecting the target argument is still pretty easy, simply put it after tsc or $(TypeScriptSourceMap):

<Message Text="Executing tsc --target ES5 $(TypeScriptSourceMap) @(TypeScriptCompile ->'&quot;%(fullpath)&quot;', ' ')" />
<Exec Command="tsc --target ES5 $(TypeScriptSourceMap) @(TypeScriptCompile ->'&quot;%(fullpath)&quot;', ' ')" />
