I have an ASP.NET 1.1 project and am trying to open it in VS 2005. Note that I have a backup of the original project already taken manually, in a separate location.

It triggers the upgrade wizard/converter that says I must convert the files to the new version. I've tried running the wizard with various combinations but with no luck.

When I run the upgrade wizard with the 'Backup' option, it reports an error saying:

ERROR: Failed to backup website http://localhost/foo.bar/foo.bar.csproj

Foo.Bar is the name of my solution and also the project file.

When I run the upgrade wizard without choosing the backup option, i.e. with the 'No backup' option, it reports that it has converted the solution successfully. However, in the Solution Explorer, there is only 1 child node for the solution and it reads:

http://localhost/foo.bar/foo.bar.csproj

It has no files or child nodes under it.

Please help.

 This is only from my experience and that of co-workers, I don't think there is any documentation about this but we all had issues using the conversion wizard from VS 2003 projects to VS 2005 until VS 2003 was uninstalled. We discovered this because two people out of our group of 5 did NOT have VS 2003 installed and when THEY attempted to convert the projects they had no problems.

To test this, I uninstalled VS 2003 and then was able to successfully convert from 2003 (1.1) to 2005 (2.0).

I don't know if that is an option for you or not, but just wanted to share my experience.

Hi,

For "ERROR: Failed to backup website http://localhost/foo.bar/foo.bar.csproj", please check whether there is already a file with the same name. For more information, see http://msdn.microsoft.com/en-us/library/60z6y467%28VS.80%29.aspx

You also can create new solution from Visual Studio, and add the project to this new one, and use Visual Studio 2005 to open it.

I look forward to hearing from you.
