Well, there were two things.

On the first occasion, it didn't work as it should have been because of a bug in the interface. Basically, when the object ID is not recognized in the aspx page, we have to restart the interface. Once loaded again, everything works as usual. I had to restart three times last night. After a while, those error messages start appearing even if I don't do any change in the code.

Then, as I added the namespace in my DLL, I had to use Framework.Framework.App for the object to be created.
