Targeting ES5 with TypeScript in Visual Studio

Question

I would like to use get/set syntax in TypeScript within Visual Studio Express for Web. How do I enable this. I currently get this error when compiling;

Property accessors are only available when targeting ES5 or greater

The file being compiled has a build action of TypeScriptCompile. I don't know how to add a the necessary compiler switch from within Visual Studio.

Any help would be appreciated.

This has changed with TypeScript 0.8.2. You now change TypeScriptTarget in the .csproj file from:

<TypeScriptTarget>ES3</TypeScriptTarget> 

to

<TypeScriptTarget>ES5</TypeScriptTarget> 

MyApp.csproj:

  <PropertyGroup Condition="'$(Configuration)' == 'Debug'">     <TypeScriptTarget>ES5</TypeScriptTarget>     <TypeScriptIncludeComments>true</TypeScriptIncludeComments>     <TypeScriptSourceMap>true</TypeScriptSourceMap>     <TypeScriptModuleKind>AMD</TypeScriptModuleKind>   </PropertyGroup>    <PropertyGroup Condition="'$(Configuration)' == 'Release'">     <TypeScriptTarget>ES5</TypeScriptTarget>     <TypeScriptIncludeComments>false</TypeScriptIncludeComments>     <TypeScriptSourceMap>false</TypeScriptSourceMap>     <TypeScriptModuleKind>AMD</TypeScriptModuleKind>   </PropertyGroup>
