 reportviewer rv = new reportviewer();

error 1 

the type 'system.windows.forms.usercontrol' defined in assembly not referenced.

you must add reference assembly 

 'system.windows.forms, version=2.0.0.0, culture=neutral, publickeytoken=b77a5c561934e089'. c:\users\dsingh\documents\visual studio 2012\projects\rd\rd\mainwindow.xaml.cs  27  13  rd

your error answers question, try adding windows forms assembly. follow following steps

  1. right click on project in visual studio
  2. click on add reference option
  3. click on .net tab
  4. scroll system.windows.forms component name
  5. click on add reference

and don't forget add reference in window or page start tag. follow link provided in below comment fredrikredin
