It was not long ago when VS2010 RC become available. One unfortunate thing with it, was that the SL 4 BETA tools were not supported on VS 2010 RC and there were tons of question when shall we expect version of SL 4 tools that will work with VS 2010 RC. Well, here they are:
Silverlight 4 RC Developer Runtime + Silverlight 4 Tools for VS 2010 RC + WCF RIA Services RC.
I am not sure whether to be happy or sad for the last one. I was exploring the .NET RIA Services since their early CTP and I do have a project that uses Silverlight 3 RTM + WCF RIA Services Beta all developed on VS 2008. What was my surprise when I saw the installer splash screen of Silverlight 4 RC Tools. It was so kind to tell me that I have earlier version of WCF RIA Services, which will be uninstalled for the sake of new RC version. However, WCF RIA Services RC will only support Silverlight 4 and Visual Studio 2010 RC. So I decided to not make that big upgrade step of my project, because it is bit more complex than just a Silverlight application :). Anyway I know that sooner or later I will have to upgrade everything to 2010 versions because in either way WCF RIA Services will not support Silverlight 3.
The only solution to “touch” Silverlight 4 RC Tools without crashing all my previous work is to use a VM to play around. I just feel I have too many VMs :) I am saving one separate real HDD for all my VMs …
