The generated class for context.tt does not compile.

There seems to be an addition with multioutput support that broke this class. I explain it in more detail as a comment in the code on github's blame for the code here.

I'm using the most recent master, so perhaps there was something down the line that removed the invalid method call, but I haven't been able to track that down. The workaround for me has been to remove the .First() method from the PrimaryKey accessor.
