Wield the Power of Generic Type Inference

One class that bothers me in the .NET Framework is KeyValuePair<K, V>. To create one these, you must explicitly declare the generic types being used. var pair = new KeyValuePair<int, string>(42, "The Answer");The .NET Framework support generic type inference, so why did the designer of the KeyValuePair<K, V> class decide it would be good idea to force us to write out the types? Take a look at another type of pair from .NET 4: the 2-valued Tuple.
