Last week Silverlight 1.1 Tools Alpha for VS 2008 RTM were released and as a developer working with Silverlight I run to install them on my fresh new copy of VS 2008 RTM. The installation went without any problems, but unfortunately after trying to create a new Silverlight project (same for class library) I got a popup error saying:
"The project file 'C:\Users\estoychev\AppData\Local\Temp\zhxiyguv.4rr\Temp\SilverlightProject1.csproj' cannot be opened. The project type is not supported by this installation."
Puff. I tried to google about this error message but I got no helpful results. I only noticed that a guy commented on the ScottGu's blog with the same problem. Scott kindly replied to this guy to mail him and he would attach someone to help for this problem. I followed his advice and wrote to him. The next day I received an answer from Bill Hiebert guiding me how to resolve my problem. The simple step you should take is the following:
Open a Visual Studio Command prompt and type "devenv /resetskippkgs".
Then try to create a new Silverlight project. This solution does work for me. I hope it also works for you. Thanks Bill ;)
