I verified that this is fixed in Mono 2.0p1 on SLED 10 sp2 i586.


Output of test case on Mono 1.9.1:
c220:~/bug359611 # gmcs tc.cs 
tc.cs(13,48): error CS0266: Cannot implicitly convert type
`System.Linq.IOrderedEnumerable<T>' to
`System.Collections.Generic.IEnumerable<T>'. An explicit conversion exists (are
you missing a cast?)
tc.cs(13,48): error CS1662: Cannot convert `lambda expression' to delegate type
`System.Func<System.Collections.Generic.IEnumerable<T>,System.Collections.Generic.IEnumerable<T>>'
because some of the return types in the block are not implicitly convertible to
the delegate return type
Compilation failed: 2 error(s), 0 warnings

Output of test case on Mono 2.0p1:
