Some people want to see the DB structure and dont have VS, is there a way to do this? Or any other way to export it outside of a screencapture (it is a huge diagram).
You can right click on the design surface and select Diagram -> Export as Image and you get the entire edmx model generated as bmp
This doesn't really work on large diagrams. Oh it exports it, but on a large diagram, once you zoom in, all text is nothing but pixels. It's a logged bug, but right now Microsoft is not planning on fixing this issue.
What I've done is downloaded a pdf printer (like Bullzip free edition), then just "print" the document to pdf.
To Viso, no. I have yet to find a way to export this to Visio.
