Is there any convenient way to add a value when the dictionary key does not exist?

[zms9110750]

My current code:

GetValue=>
dic.TryGetValue(name, out T com) ? com : dic[name] = Find( name);

Lazy can tell him how to get the value in advance. Is there any way to use it with a dictionary?

This is not a language specific question, and should belong to the dotnet/runtime repo.
