Hi Clive Hoggar,
Yes, the answer is "no problem" indeed :). The .NET framework 3.5 is fully backward compatible with .NET2.0, you only need to update your web.config
to use the .NET3.5 framework. This can be done automatically by Visual Studio, once you open the project in it, it will ask you whether you want to convert the project to use newer framework. If you do not convert the project, you will not be able to use the new framework features, but it will still work.
As additional information, we will release a .Net3.5 build with our next version.
