The type ‘local:LevelToVisibilityConverter’ was not found. Verify that you are not missing an assembly reference and that all referenced assemblies have been built.
What I am I missing here?
Looking forward for an solution, thank you.
You need to include the Xml-Namespace of the Namespace where your LevelToVisibilityConverter is in your Assembly.
Assume your LevelToVisibilityConverter is in Namespace SLGridImage you have to add the XML-Namespace (xmlns:local=”clr-namespace:SLGridImage”) as follows
