Microsoft is constantly shipping products. Some products, like SQL Server 2005, had dependencies on other products and needed to wait for the other team to finish their code. SQL Server had to wait for the Visual Studio team to finish for example. Sometimes Microsoft releases the software in staggered waves. . VS 2005 shipped with .NET 2.0. A year later .NET 3.0 shipped. VS 2005 didn’t know how to code WPF projects so Microsoft had to release a patch.
The same problem is cropping up this year with Silverlight and Visual Studio 2008. Beware trying to create a Silverlight application with Visual Studio 2008 (RTM) You’ll see the following message.
“Package Load Failure
Package ‘Microsoft.VisualStudio.Silverlight.SLPackage, Microsoft.VisualStudio.Silverlight, Version=184.108.40.206,…”
At least you will if you have the old version of Silverlight 1.1 Tools Alpha installed.
Get the latest Silverlight 1.1 Tools Alpha for Visual Studio 2008 and you should be alright.
Warning: I had to uninstall the previous version first.
