[Opensim-dev] C# 3.0 vs .Net 2

Thu Mar 26 10:47:21 UTC 2009

You may find some issues with that since it's a CTP (pre-beta) from
2006, so some supported syntax in there may have changed for final
release, but can't say for certain. 

Teravus is correct in that VS2008 is available for free
(http://www.microsoft.com/express/vcsharp/). Installing C# 2008 Express
you also get SQL Server 2008 Express installed, so you have some options
for using that out of the box too. C# Express should be able to handle
most basic development tasks - I guess it just depends on how nice you
want to be to 2005 Pro or higher owners going forward as to whether to
stay in 2.0 land or move on.

Could anybody actually using VS 2005 comment on whether installing the
Orcas CTP would solve this?

This is the community preview of the C# 3 extensions, made available as
an extension to VS 2005.
