Yes - we've got previews of this already in the form of our IronPython 2.6 CTP for .NET 4.0 Beta 2 (and previously beta 1 release). We are continuing to update 2.6 for better .NET 4.0 compatbility and the plan is to ship a 2.6.x release in both .NET 2.0 and .NET 4.0 flavors around when .NET 4.0 ships.

While IronPython built for .NET 2.0 would probably run fine on .NET 4.0 we haven't done any testing to make sure that's the case. Additionally it would cause a lot of confusion because we have been putting out .NET 4.0 compatible releases which use new functionality that we usually ship as part of IronPython (Microsoft.Scripting.Core - the portions of the DLR shipping in .NET 4.0). Therefore lots of people would probably try and use C#/VB.NET's new dynamic support to talk to IronPython and it would fail but it wouldn't be entirely obvious why it's not working. You should just be able to install .NET 2.0 SP1 in addition to 4.0 and things should work. .NET 4.0 is certainly a later version and that's why the message explicitly calls out that .NET 4.0 isn't supported :) It means later in the 2.0/3.0/3.5 series of runtimes which are all in place upgrades.

I have recently tried to install the latest 2.6 final and it complains about "requires .NET Framework 2.0 SP1 or later. NET 4.0 is not supported". I have installed .NET 4.0 as part of the Visual express 2010 software. Is there any way I can convince IronPython to update itself without uninstalling the visual express software. Also isn't .NET 4.0 a later version of .NET 2.0 Thanks David Waller
