WPF Desktop client on Win XP

[mhemant]

We need to use WPF desktop application on Windows XP. I know Microsoft has stopped the support for XP. Can you please let me know which .NET version i need to install? Any idea what will be disadvantages?

You should use the latest version that is supported with XP which is 4.0. Note that it requires XP service pack 3. The disadvantages are that you can't use features of newer .Net versions and that support for version 4.0 has ended January 2016.
