Fix C# query to give results in the same format as java.

[starcke]

C# didnt recognize the modeled methods because the api name differed from the Java one and therefore the split up didnt work as expected. This makes a change to fix that. We'll look at whether this is something that should be upstreamed or whether it only makes sense for the extension.
