1. I am using windows 7 running .net 4.0

3. They are using windows XP .net 3.0 and 3.5
4. They can not update to .net 4 for business reasons.
5. I am running Visual studio 2010

How can i make my application backwards compatible so that they can use it?

Answer 1

If you don't use any .NET 4 specific features, just target 3.0 or 3.5. That will solve any compatibility problems. Here's a link on MSDN detailing how to do it:

• On the Project menu, click ProjectName Properties.
• Click the Application tab.
• In the Target Framework list, select either .NET Framework 2.0, .NET Framework 3.0, or .NET Framework 3.5.
