Hi,
There is one walkthrough in CRM SDK — Add a Custom Tab to a Specific Entity.
I have modified it to work for only the form of the entity.
And the tab and the button would appear only in case of existing record (not while record is getting created)
To use the code just replace new_case with the name of the entity and get the images from the walkthrough folder.
