title: How to set DNX452 target in ASP.NET 5?
body: <p>I'm trying to build an MVC project in ASP.NET 5. This project has dependencies on the .NET 4.5.2 framework, and I'm having issues getting it to work.</p>
  
  <p>I've updated my project.json file to use "dnx452":</p>
  
  <pre><code>  "frameworks": {
      "dnx452": {
        "dependencies": {
        },
        "frameworkAssemblies": {
          "System.ServiceModel": "4.0.0.0"
        }
      }
    },
  </code></pre>
  
  <p>And I've updated my runtime to the latest version (1.0.0-beta6-12174), which I'm told has 4.5.2 support.</p>
  
  <p>But whenever I run the project, I get the following error, indicating that I'm still targeting 4.5.1 somehow, and I simply cannot figure out how to change it:</p>
  
  <pre><code>The current runtime target framework is not compatible with 'WebMvc'.
  
  Current runtime Target Framework: 'DNX,Version=v4.5.1 (dnx451)'
   Type: CLR
   Architecture: x86
   Version: 1.0.0-beta6-12174
  
  Please make sure the runtime matches a framework specified in project.json
  </code></pre>
  
  <p>Any thoughts? Thanks!</p>
