Do you love the Hot Towel SPA template by John Papa ? 
Do you like TypeScript? 
Would you like to implement your viewmodel classes of Hot Towel in TypeScript? 
This project demonstrates how to do just that. It includes a blank Hot Towel project that has been converted to use TypeScript for the view models. 

Requirements: 
1. Visual studio 2012 or 2013
2. TypeScript, latest version, currently 0.9.1.1 
3. TypeScript TypeScriptModuleKind option set to AMD (see below..)

About Web Essentials:
From version 3.9 of Web Essentials, it no longer supports TypeScript.
This latest update of this project includes changes in the project file to battle this unfortunate change.

TypeScript working with Durandal requires TypeScript files to be compiled as AMD modules.
Usable settings for TypeScript compile options are not currently available in VS2012.

Following sections had to be injected in the project file to make this work:
  <PropertyGroup Condition="'$(Configuration)' == 'Debug'">
    <TypeScriptTarget>ES5</TypeScriptTarget>
    <TypeScriptIncludeComments>true</TypeScriptIncludeComments>
    <TypeScriptGeneratesDeclarations>true</TypeScriptGeneratesDeclarations>
    <TypeScriptSourceMap>true</TypeScriptSourceMap>
    <TypeScriptModuleKind>AMD</TypeScriptModuleKind>
  </PropertyGroup>
  <PropertyGroup Condition="'$(Configuration)' == 'Release'">
    <TypeScriptTarget>ES5</TypeScriptTarget>
    <TypeScriptIncludeComments>false</TypeScriptIncludeComments>
    <TypeScriptGeneratesDeclarations>false</TypeScriptGeneratesDeclarations>
    <TypeScriptSourceMap>false</TypeScriptSourceMap>
    <TypeScriptModuleKind>AMD</TypeScriptModuleKind>
  </PropertyGroup>

and the bottom:
  <Import Project="$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v$(VisualStudioVersion)\TypeScript\Microsoft.TypeScript.targets" />

The "TypeScriptModuleKind" option above is the key to compile the TypeScripts as AMD modules.

Finally:
Please do not update the Durandal or Bootstrap packages in this project (using NuGet Package Manager).
The same applies for the current version of the HotTowel project template.
