We want to create a base class that inherits from MS WebPart class so
we can add code for every web part we develop. It seems to be fine
until we start adding in the code for part to part communication. It
is telling us that on the PartCommunicationRunAt and
PartCommunication method we are returning different types. Also on
the PartCommunicationConnect method there is a problem with the
EsureChildInterfaces. I can provide more details on the specific
errors, but my question is has anyone done this.
