I was stepping through some code and hit a method I wanted to see the code for. I clicked on 'go to definition' and it would usually take me to the method definition, but now it takes me to what appears to be an auto generated [from metadata] class. I've never experienced this before. What's going on and how do I get the old functionality back?
If it helps, the method is being called in a code behind file and the method definition is in the code behind of a UserControl.
