Get classes based on Interface with Linq

This weekend I was searching for an easy way to get all classes which implement an given interface.
After searching I found an easy way to get the classes by given type. Using Linq getting the following code:

var type = typeof(IMyInterface);

var types = AppDomain.CurrentDomain.GetAssemblies()

.ToList()

.SelectMany(s => s.GetTypes())

.Where(p => type.IsAssignableFrom(p) && !p.IsInterface);
