Yeah - one could do that. From the original post, I thought that he wanted to know how to access one from the other without coding any persistence mechanism, which can not be done. However, you could do what is shown in the article, or persist the values to disk, or whatever... But the main point is that persistence IS needed in between the two apps, you can not access one directly from the other. I liked the implementation that the article uses - Binary Serialization. I have been doing the same wherever needed in my apps and it works like a charm.
