title: Error when compiling a WinForms project that uses SubSonic library
body: <p>The code generation is working but I get the following errors when I try to build the project:  </p>
  
  <p>Error 4 Source file '...Project Path...\Structs.cs' could not be opened ('Unspecified error ') PPSGenerator
  Error 5 Source file '...Project Path...\Context.cs' could not be opened ('Unspecified error ') PPSGenerator
  Error 6 Source file '...Project Path...\ActiveRecord.cs' could not be opened ('Unspecified error ') PPSGenerator
  Error 7 Source file '...Project Path...\StoredProcedures.cs' could not be opened ('Unspecified error ') PPSGenerator</p>
  
  <p>I'm using VS2010 on a Windows 7 64 bit machine.  Project is targeting Framework 3.5...  any ideas?</p>
  
  <p>Also noticed the following warnings, but not sure that these are as important:</p>
  
  <p>Warning 1 The C# 2.0 and C# 3.5 compilers are no longer supported. Templates will always be compiled with the version 4 compiler instead of 'v3.5' as specified. ...ProjectPath...\Structs.tt 1 4 </p>
  
  <p>Warning 2 Multiple template directives were found in the template. All but the first one will be ignored. Multiple parameters to the template directive should be specified within one template directive. ...ProjectPath...\Settings.ttinclude 1 4 </p>
  
  <p>Warning 3 Compiling transformation: The variable 'parameters' is assigned but its value is never used ...ProjectPath...\SQLServer.ttinclude 92 15 </p>
  
  <p>Thanks!
