[Opensim-dev] Proposal: Drop VS 2005 suppost [Was: C# 3.0 vs .Net 2]

Thu Mar 26 11:32:04 UTC 2009

I propose that

"if nobody actually objects on this or the users list before 1st of May 2009, we'll drop VS 2005 support and move on".

If I get no strong objections on this, I'll re-post a proposal and update the wiki with the proposal and guidelines to objecting, on friday 3rd of April 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.
