ReadOnlyObservableCollection

Published on In Programming Tags #dotnet

What is the point on observing changes on a collection that is ReadOnly?

Well, I guess it is all in the name: you cannot change it but you can still know what is happening to it.

In framework 1.0 & 1.1, you had no ReadOnly implementation visible. You could create ReadOnly instances by calling static methods. I guess it was decided that it is clearer to explicitly expose the Collection as ReadOnly in the signature of the property itself, than having to read the documentation to discover it.
