Visual Studio 2008 tries to convert a web deployment project every time I open the solution

Question

I am using a web deployment project in Visual Studio 2008.

Now, every time I open my ASP.NET web project solution which contains the web deployment, Visual Studio asks to convert the project (I guess from VS 2005 to 2008). I do the conversion and save, but if I close an re-open the solution, VS insists on trying to convert the project.

Anybody who knows how to resolve this annoying problem?

Update - configuration:

• Visual Studio 2008 Professional (german)
• ASP.NET 3.5 (VB.NET as language)
• Subversion/VisualSVN
• 1 web project + 4 library projects + 1 web deployment project (new)

Answer 1

I found a solution:

• Right click on the Web Deployment Project in the Solution Explorer of Visual Studio 2008.
• Select "Open Project File"
• Change the ToolsVersion value from "3.5" to "4.0"

(XML of the .wdproj file)

<Project ToolsVersion="3.5" DefaultTargets="Build" ...

into

<Project ToolsVersion="4.0" DefaultTargets="Build" ...

That's all!
