C# backwards compatibility

  1. I am using windows 7 running .net 4.0
  2. I wrote an application on my platform then distributed it to my coworkers.
  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?

Don't use .NET 4.0 features and set the target framework to .NET 3.5 on your project. Then rebuild and redistribute. How to do it:

  • In Visual Studio, open the project you want to change.

  • Right-click the project in Solution Explorer and then click Properties.

  • In the Project Designer, locate the Target Framework list, as follows.

  • For Visual C# projects, the Target Framework list is on the Application tab of the Project Designer. For more information, see Application Page, Project Designer (C#).

  • In the Target Framework list, select the .NET Framework version or profile that you want.

More detailed information here.

Also, about don't using 4.0 features, you can read more about what C# features here.

Only use features supported by .net 3.5. Don't use any .net 4.0+ features.

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.
