Avoid boilerplate code when initializing collection properties in c#

Is there a way to avoid writing exactly the same type twice when initializing properties (or fields) in c#? (something similar to diamond operator in Java would do..)

For example, lets say I have this code:

private readonly Dictionary<string, ISomething> _dict = 
                  new Dictionary<string, ISomething>();

Is there a way to avoid writing the type Dictionary<string, ISomething>() or part of it twice?

Please note that the type is already defined as Dictionary, not IDictionary..
