The type or namespace name 'DryIoc' does not exist in the namespace

How can I resolve this error ?

I compiled Prism and checked if that type is existing. It is.

I have no idea you haven't provided any context or sample that reproduces the issue.

@dansiegel I had the same error. For context, I had a class library named Company.Prism with derived classes from Prism. Like public abstract class CommandBase : DelegateCommandBase. When that library was referenced in the Prism application project I had the following error: The type or namespace name 'DryIoc' does not exist in the namespace Company.Prism error came from the app.xaml.cs.g of the prism application project.

To workaround I changed the default namespace of the project to Company.PrismEx and it works correctly now.

Yeah you can't do that in general with .NET. The same thing can happen to you if you do something like MyLibrary.Microsoft... you'll have huge headaches with most of their packages... and god help you if you did MyLibrary.System

Thanks for the quick reply. Looks like it was the same problem in the ticket above. Weather.History.Prism.
