Solution 1

That's because your application is compiled with .Net 3.5. Presentation framework is a WPF namespace, and that means the machine has to have .net 3.5 to run it. Yes, your setup project will run on a machine with 2.0 on it, but the app will not.

Just configure the setup app to install 3.5 as a prerequisite, and you'll be gold.

In Project Properties, there is an option: "Target platform". Select v.2.0.

The compilation will be successful if you are not using new features of the .NET introduced after .NET Framework v.2.0.

[EDIT]
Thanks to the note by Philippe below, I noticed that this is exactly the case, as you try to use WPF. There is no WPF in v.2.0, so one can only use WPF with .NET Framework 3.0 or later. That said, WPF cannot be used in Windows 2000, it needs XP or later version of Windows. If the Windows version is XP or later, there is no need to use .NET Framework 2.0. Anyone can install v.3.5 or 4.0, which I would recommend to anyone who uses XP or later version of Windows. Redistributable .NET Framework can also be easily deployed with the application.
[END EDIT]

At the same time, you can keep using C# v.3 in your source code. The compiled assemblies will work with .NET Framework v.2.0.
