Question

I know we are really behind the times here, but we are just about to upgrade from .NET 1.1 to .NET 2.0.

Thank you for your sympathy.

Anyhow, are there any gotchas we should look out for?
Do you have any general advice before we jump in?

Please do not post telling me to go straight to 3.5: 2.0 is all we’re allowed!

We’re using mostly C#.

Here is my recommendation before upgrading:

• If you are used to use Visual Studio 2003, you will need to go for VS2005. You will have to convert the old solutions and projects so that it will be compatible with VS2005. Make sure to have a backup of the project you’re going to convert so that you can roll back or even use it as source for any modification you may need to the converted projects.
• If you’re developing web applications using .NET 1.1, make sure that all the virtual directories and applications in the IIS is configured to work with ASP.NET 2.0. You may need also to configure a new Application Pool for your .NET 2.0 applications.
• If you’re using any third party libraries in your .NET 1.1 projects, you may need to confirm its compatibility with .NET 2.0 projects. Some old libraries used in .NET 1.1 are not compatible with 2.0.
