I'm working on the Microsoft white paper at
http://msdn.microsoft.com/library/default.asp url=/library/en-us/odc_vsto2003_ta/html/ExcelObj.asp
"Understanding the Excel Object Model from a .NET Developer's Perspective"
This paper was written for Visual Studio 2003, but I thought I should use the latest and greatest anyway, so I downloaded and opened the solution file in Visual Studio 2005 (RTM - not beta). I discovered that an automated conversion is triggered!
The conversion DID NOT succeed due to this error:
The project file C:\ .... \ExcelObjectModelVB.vbproj cannot be opened.
The project type is not supported by this installation.
Type "vbproj" is not supported by Visual Studio 2005
(I'm sure I installed everything for Visual Basic!)
What's going on here I thought the conversion from VB 6 to .NET was inadequate. This is worse.

Type vbproj not supported by Visual Studio 2005???

VSTO might be the problem. I have VSTO for 2003 but I did not download the 2005 because it's still beta. In any case, I quoted the error message exactly:
The project file C:\ .... \ExcelObjectModelVB.vbproj cannot be opened.
The project type is not supported by this installation.
... and that certainly seems like a strange error message if VSTO is the problem.

What version of Visual Studio did you install on your machine Pro Express If Express, which language Did you ever have Beta 2 installed on this machine, or any of our technology previews
I downloaded the sample and upgraded it with my install of Visual Studio 2005 and was able to get it to work successfully. There were even specifical dialogs warning me about security changes between the two versions when working with Visual Studio Tools for Office. Is it possible that you don't have VSTO installed

fdiros,
I am having what looks like the same issue. Did you find a solution

Seigfried,
I am sorry you are having trouble with the conversion of this project. Does this occur with all types of applications For example, if you create a simple winform app (hello world) in 2003 and then open it in 2005, does it convert properly You should experiment there to isolate the issue.
As a workaround, I recommend creating a new project in VS 2005 and importing the necessary files etc. into 2005. that will at least keep you moving forward.
John.
