Hello IronPython Community, a couple months ago we began using the beta 
versions of .NET 3.5 and Visual Studio 2008 for IronPython development.  With 
respect to the IronPython sources this means that we had to upgrade the Visual 
Studio 2005 solution file, IronPython.sln, to Visual Studio 2008.  We are *not* 
using any new C# 3.0 features at this time and actually pass a flag to the 
msbuild tool ensuring that we're building and testing against .NET 2.0.

Since this change occurred, we've been backporting solution file modifications 
to the 2005 version and testing the 2008 version as well for the 2.0 Alpha 
releases.  Now that .NET 3.5 and Visual Studio 2008 have been officially 
released, we'd like to begin distributing only the 2008 solution file.  The 
major reason for wanting to do this is so that we can get IP releases out more 
quickly (i.e., no need to rerun all of our tests on sources built under VS2005 
or manually modify the 2005 solution file).

The impact on Windows users who build IronPython from sources would be:
* It will be necessary to install .NET 3.5 or Visual Studio 2008 to get the new 
version of msbuild
* When building IronPython.sln from the command-line, you'll need to pass in an 
extra argument - "/ToolsVersion:2.0" - to msbuild

We felt it would be best get feedback from users who build IP from sources 
before making this change.  Ideally we'd like to make the switch for the next 
Alpha release (which should be available around the third week of December), 
but the change could be delayed if there are many objections.  All comments are 
welcome!
