Description Lopatkin Ilja 2013-05-15 01:13:35 UTC
We have a simple class like that:

class TestClass {
    public Func<bool> Predicate { get; private set; }
}

When trying to generate constructor with this property MD fails with exception:

System.InvalidOperationException: Cannot parameterize a type with type arguments from a different compilation.

Works for me with master - maybe you just got an unlucky push :/
Comment 2 Lopatkin Ilja 2013-05-16 00:21:44 UTC
Well, that's strange. The official buid of XamarinStudio works just fine. But that can't be just an unlucky push because that problem is bothering me for several months.
P.S. Just found out. In fact, it does work if I open code generation window, then just close it and then open again.
Comment 3 PJ 2013-06-24 16:18:38 UTC
This bug was marked as fixed for Xamarin Studio 4.0.9, which is currently in the beta channel. Try it out!
Comment 4 Lopatkin Ilja 2013-09-25 00:49:48 UTC
No, it's still broken. Moreover, now it crashes in both official build and trunk version.
Comment 5 Mike Krüger 2013-09-25 01:10:18 UTC
Ok now I could verify it - the 2nd time it fails for me as well.

/fixed
Comment 6 Lopatkin Ilja 2013-09-25 01:14:18 UTC
Great, thanks! It was really annoying. :)
