title: Visual Studio 15 Compilation Fails- clean project
body: <p>I am using Visual Studio 15 Preview 3</p>
  
  <p>When I create a new project (ASP.Net 5 "Empty" project) and press build all it fails to build. I get the following errors.</p>
  
  <pre><code>Severity    Code    Description Project File    Line    Suppression State
  Error   MSB4063 The "VsTsc" task could not be initialized with its input parameters.    WebApplication3 C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v15.0\TypeScript\Microsoft.TypeScript.targets 247 
  Error   MSB4064 The "OutputLogFile" parameter is not supported by the "VsTsc" task. Verify the parameter exists on the task, and it is a settable public instance property. WebApplication3 C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v15.0\TypeScript\Microsoft.TypeScript.targets 261 
  </code></pre>
  
  <p>Any suggestions please.  I have added no code, just created the project and pressed build.</p>
