I would say that performance is paramount, and I'm assuming that everyone else would agree. I think it's a great idea to try both IKVM and Sharpen and then make a few benchmarks that we compare both.

Teacher Evaluation 2.0 - http://tntp.org/eval2.0 -----Original Message----- From: Hans Merkl [mailto:h...@hmerkl.com] Sent: Wednesday, November 10, 2010 8:37 AM To: lucene-net-dev@lucene.apache.org Subject: Re: Porting Automation - Sharpen What I got from previous discussions was that IKVM works quite well, but some people don't like the idea because it produces its own wrappers around Java code. E.g. a collection won't be represented as .NET collection. Performance also seems to be close the .NET version (a bit slower).
