[Opensim-dev] OpenSimulator development code now builds using .NET 4.0

[Justin Clark-Casey]

Hello folks,

As discussed previously in the opensim-dev mailing list [1], the minimum .net framework version required by 
OpenSimulator is now .NET 4.0 in the development branch.

On Windows, this means that one must have the .NET 4 Framework installed to run OpenSimulator.  Previously, 
OpenSimulator ran with the .NET 3.5 framework.

Also on Windows, this also means that to build OpenSimulator, you must use Visual C# 2010 [Express], 2008 does not 
support .NET 4.0.  So runprebuild.bat now creates a 2010 solution.  I'm sure 2012 can also be used but I'll leave it to 
someone else to create a runprebuild2012.bat.

On Mono, this raises the official minimum Mono version to 2.10.8.1.  If you already have at least this version installed 
(which is the case for all the current major Linux distro versions) then you don't need to do anything.  At the moment, 
older versions of Mono will continue to work as well but this will change once someone uses some .NET 4.0 specific 
syntax or SDK functionality.

If you are building nant and using an old version (pre 0.91 or earlier, I think) then you may need to update this to 
0.91 or later.
