Conflict in commands

[MohammadRezaKashi]

I have implemented my WPF project by MVVM design pattern so I needed to implement observable class by myself.
Now it has conflicts with handy controls commands.
How can I solve this problem?

As mentioned in the documentation, all commands are in the HandyControl.Tools.Command namespace
To prevent interference, you can do the following

1. If you do not need this namespace, delete it
2. Use the appropriate namespace when creating your class

namespace myproject.mycommand
     public class command {}

3. If the above does not solve your problem, you can use the following method
   using DelegateCommand = HandyControl.Tools.Command;

Replace your class name and namespace
