after some delay, finally I could release Npgsql 1.0beta2.
This release has a lot of bug fixes and features a huge performance improvement, thanks Hubert Fongarnand and Bryan Mayland who sent a lot of optimizations to Npgsql.
Also, on this release, for the first time we release assemblies for .net 2.0, mono and ms implementations.
You can download it from Npgsql homepage
Please, give it a try and let me know if you have any problems with it.
Thanks God for allowing me to make this happen.
Thanks all who helped with patches and feedbacks.
