The answer I'd give you is simple:

DON'T

Session storage is volatile, doesn't scale and is bound to bring lots of problems. Rather than use session for live object storage, use it to store reference pointers and reload the data. Don't build a desktop app on the Web :-)

When using MM.NET 'Classic' entities, to save a business object on a web form, you had to store the dataset of the business object in a session variable in the page_load method and then re-establish it in the click event of the 'Save' button before saving the dataset.
