ImportMany collection property has no setter, and it is always empty in the runtime.

I remember the bug #94 was fixed. But when I removed 'set', and imported collection becomes empty. I noticed it in a recent d16.0stg build.

We have a test for what you describe:

What is different about your case that leads it to fail?

[lifengl]

interesting, I hit this problem on a head of a MEF scope (UnconfiguredProjectImpl), so it is coming from ExportFactory.CreateExport(). I wonder whether that makes any difference.

Would you be willing to try adding a test for it to see if you can repro it?
