.csproj cannot be opened by VS 2008

[John Smith]

While trying to open up MyTest.sln in VS 2008 I got the following
error:

'MyTest.csproj ' cannot be opened because its project type (.csproj)
is not supported by this version of the application.
To open it, please use a version that supports this type of object.

My system info:
OS: Win XP Pro SP3

Microsoft Visual Studio 2008
Version 9.0.30729.1 SP
Microsoft .NET Framework
Version 3.5 SP1

Installed Edition: IDE Standard

SQL Server Analysis Services
Microsoft SQL Server Analysis Services Designer
Version 10.0.1600.22

SQL Server Integration Services
Microsoft SQL Server Integration Services Designer
Version 10.0.1600.22 ((SQL_PreRelease).080709-1414 )

SQL Server Reporting Services
Microsoft SQL Server Reporting Services Designers
Version 10.0.1600.22

Had a look at http://msdn.microsoft.com/en-us/library/ms247038(VS.90).aspx
but I was able to confirm with my co-worker that the VS 2008 should be
the correct version for opening up the project; therefore the
suggestion of installing a different version of VS does not apply. I
pretty much have the same problem as the first poster under "community
content" but unfortunately no one replied him.

I also tried creating another project MyTestIS.sln containing
MyTestIS.dtproj which opened up successfully in VS.

Any suggestions in how to resolve the error?

Thanks.

It sounds like your version of Visual Studio is the one that is you get when
you install SQL Server client tools (and probably says "Business
Intelligence Development Studio" in your Programs menu). That version of VS
only has the capability of working with SQL-related projects, like
databases, Reporting Services, and SSIS. You would need to install Visual
Studio from a "real" Visual Studio disc to have access to C#/VB.NET/C++.
