title: Using ReportViewer in VS 2013
body: <p>I have a VS 2010 WPF application which uses ReportViewer (RDLC) which I am trying to build in VS 2013. I am having a problem with the build. In 2010 (.NET 4) it worked fine with Microsoft.ReportViewer.WinForms.</p>
  
  <p>To build under 2013, I found two NuGet packages:
  Micosoft.ReportViewer.WebForms v 11.0.0.0 (note spelling error!)
  and:
  ReportViewer.Common 10.0</p>
  
  <p>Using the first one, an error message tells me:
  error CS0012: The type 'System.Web.UI.IScriptControl' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'</p>
  
  <p>I can't seem to find this exact assembly; using any other version, I get:
  error MC1000: Unknown build error, 'Binary format of the specified custom attribute was invalid.'</p>
  
  <p>I've tried with my application targeting .NET 4.0 and also tried targeting 4.5.1; nothing seems to work.</p>
  
  <p>How can I build a WPF application using VS 2013, targeting at least .NET 4.0 (although I'd prefer newer), and using RDLC?</p>
  
  <p>What components do I need to install? What NuGet packages should I use? What assemblies (versions) should I reference, and where do I find them?</p>
