#77725
In .NET 7.0 we had some code refactoring and fixes in configuration. This change had been handling the binding to
ICollction<T>
andIList<T>
by creating underlyingArray<T>
object. It is obvious the returned object is not expandable which means users cannot add more items to that object. This is wrong and regression from previous versions of .NET/Core. The fix here is in case of binding toICollction<T>
andIList<T>
, we'll createList<T>
object instead which is expandable and allow adding more items to such object.#77725 is a good example demonstrating this problem.
