Seems that I was not crystal clear (happens a lot :)
I meant that you were able to make your own manager class working and it 
seems that the initialization almost duplicates the code in the Manager 
class. As Nazgul said he will refactor the code further to eliminate the 
code duplication. However meantime I will copy your code for my parser 
stuff because I simply cannot decipher exactly what is needed to make 
that ManagerClass working... So no suggestions here, I have just lost in 
the code :(

This suggestion was directed to Malekith and Nazgul since they are who 
refactor the compiler right now.
If they implement it that way then neither the completion engine not the 
msbuild stuff would need to parse the errors
(nor the compiler service when opening winforms in the designer nor my 
parse stuff, etc...)
