.csproj incompatibility

Oct 30, 2008 at 5:22 AM

What version of VS were the .csproj files created with?  I am unable to open them with VS2008 sp1.  I get the following error when trying to open the .sln:
"The project file '[SlideShow]\SlideShow.csproj' cannot be opened.  The project type is not supported by this installation."

I am running:
Microsoft Visual Studio 2008
Version 9.0.30729.1 SP
Microsoft .NET Framework
Version 3.5 SP1

Installed Edition: Professional

Microsoft Visual C# 2008   91605-270-1095157-60589
Microsoft Visual C# 2008

Microsoft Visual Web Developer 2008   91605-270-1095157-60589
Microsoft Visual Web Developer 2008

Sorry, new to Silverlight 2.0.  Failed to realize I needed to install the SL toolkit in order to build the project.

After installation of the toolkit the project opens correctly in VS2008
