UPDATE: 16th December: I felt it fair to update the post with my findings
At my company we have a great DSL based tool for generating WCF Services.
However, because of various reasons, the tool will only run under Visual Studio 2005 and not the all new and great Visual Studio 2008.
That is a pity, because I wanted to show off a new concept and hence wanted to use the WPF designer in 2008 to make an impression for the client.
I’m I thought I was in luck! Apparently I can use the same projects in VS 2005 in VS 2008 and vice versa. So you don’t have to abandon VS 2005 to try out the new features in VS 2008 in your projects… this is good stuff Microsoft!
I should have read the article more closely: I opened up my VS 2005 C# library project in VS 2008.. and it gave me an upgrade wizard 😦
Luckially I was able to use my assemblies from VS 2008 with no trouble, but it could have been so much better.
