I decided to try using Visual Studio 2010 Beta 1 to open CSLA .NET for Windows 3.6.3.

Unfortunately this isn’t as smooth as one would hope.

VS runs an upgrade wizard on the solution, but this breaks the project file. I had to manually edit the project file using notepad to remove a bunch of stuff in the configuration. How did I know what to remove? I created a brand new Class Library project for .NET 4.0 and compared the contents of that file to the Csla file…

Now that I could open the solution I figured it would just build. Unfortunately not.

Two references were broken: System.ComponentModel.dll and System.Runtime.Serialization.dll. Perhaps the project references them by version number, I’m not sure. I do know that the references were broken, so I removed and re-added the references to these files.

Next is an issue with the web service reference required for the old asmx data portal channel. I suspect the issue is that I need to update (or remove and re-add) the service reference to the web services host. But I am not entirely sure it is worth carrying this legacy channel forward (or the Remoting or Enterprise Services ones) into CSLA .NET 4.0 – WCF is the preferred solution after all, and it has been around for a few years. So at least for now I just removed the service reference, the web service proxy class in Csla.DataPortalClient and the web service host class in Csla.Server.Hosts.

The result is that the solution builds. I haven’t tried running (or building) the unit test project yet, and I suspect there’ll be a few issues there as well, but at least the basic build of Csla.dll is now possible.
