The project 'proj1.csproj' must be converted to the current project format error

Matt

When I tried to open an existing proj1.csproj in VS.NET 2003. It pops up a
dialog saying

"The project 'proj1.csproj' must be converted to the current project format.
After it has been converted, you will not be able to edit this project in
previous versions of Visual Studio. Convert and open this project?"

I am not sure what VS.NET version to create proj1.csproj. Is it because
proj1.csproj was created by older version of VS.NET? So the projects are not
forward and backward compatibles?

Please advise. Thanks!!

I believe that's the warning you get when opening a project from VS.Net 2002
in VS.Net 2003. I've always said yes and never had a problem. I've never
tried to opena VS.Net 2003 project in 2002, so if that's something you need
to do, you should create a copy first and try it out.

Yes, the project file formats changed in 1.1/VS 2003, which is the reason
for the message. The project was pry developed in 1.0/VS 2002. This is
usually not a problem, but if you open and compile the code in 1.1, I also
suggest full re-testing of the application as there were some subtle
changes introduced in 1.1, which depending on your app, may impact you.
Otherwise most of the time they convert to 1.1 without modification.

FYI, in case you ever need to convert project files, see the Switch Tools
section here:

For most users, this new feature is actually very convenient. If you want to control the update process,...
