Suppose we have merge dictionary GridRes where we override several templates for grid

Suppose we have resource dictionary AllResources where we merged GridRes

Suppose we have a form with a grid where we programmatically or via xaml loaded AllResources as merged dictionary.

Override templates were not overrided with redefined for grid (but when we copy them from gridRes to Resources of window all goes fine)

So mergeddictionary's merged dictionaries are not handled well.

We appreciate the feedback. However, this issue will not be addressed in the next version of WPF. Thank you.

We see the same thing.

When we nest merge dictionaries together of 3 levels or deeper things don't work. The suggested workaround to create a "dummy" default style at the root or anywhere else also doesn't fix anything. Seems like a bug to me.Please fix.

Merge(Resources, MyDictionaryWithMergedDicsInside);

public static void Merge(ResourceDictionary formDict, ResourceDictionary src)
            foreach (var key in src.Keys)
                if (formDict.Contains(key))
                    formDict[key] = src[key];
                    formDict.Add(key, src[key]);

            foreach (var mergedDic in src.MergedDictionaries)
                MergeDictionary(formDict, mergedDic);
