Visual Studio 2011 Conversion Wizard woes

I thought I’d try out the Developer Preview of Visual Studio 2011 as I had heard there was round-tripping between VS 2010 and VS 2011. After opening a VS 2010 project in VS 2011, I was presented with the Visual Studio Conversion Wizard, which I thought was fine. I converted the project and started working. Trying to open the project in VS 2010, I was shown the Conversion Wizard again, and thinking this was normal went through the steps.

However, every time I would open the project in VS 2010, I would still get the Conversion Wizard. This was getting irritating so decided to do some spelunking into the .sln and .csproj files with Notepad2 to see what was up.

I noticed in the .csproj file in the first <PropertyGroup> section there is an element, <FileUpgradeFlags> which had a value of 40. I removed the value, so the entry is now <FileUpgradeFlags></FileUpgradeFlags>. Saving the .csproj file then opening in VS 2010, the Conversion Wizard doesn’t appear now, so I think the problem is solved.

Does anyone know why this happens? So much for using software that isn’t even in beta yet.

I do not think the project round tripping made it into the developer preview of Visual Studio 2011

Had the same problem with 2012 RC.

Clearing the FileUpgradeFlags element's value did the trick.
