I would like to make some changes to my EF4 edmx file without modifying the file itself, mainly so I don’t loose all my changes if I regenerate the model from the database. I’m familiar with XSL and have seen references made to using it in conjunction with the edmx file. This sounds like a great solution, however I can’t seem to find any documentation on how to actually set this up. Do you reference the style sheet from the edmx file or do you configure it to look at the template and then load the edmx file in somehow? Any resources on this are appreciated.
Clarification:
Specifically what I’m trying to do is modify the model so that several of the views act as tables with relations within the model, see here: http://blogs.msdn.com/b/alexj/archive/2009/09/01/tip-34-how-to-work-with-updatable-views.aspx
The issue I’ll have in using that method is if I need to update the database and regenerate the model I’ll have to go back and make all of those changes again, I was hoping there was a way to use xslt to make those changes to the views so they would not be removed when the model is regenerated.

What do you mean by “make some changes to my EF4 edmx file without modifying the file itself”. Do you want to create a derived edmx from the original? If so, you need to be aware that C# code (= class definitions) is automatically generated during Save.
I worked on EF projects, and used XSLT to post-process edmx files and/or generate additional code. This was invoked either manually or from a batch file during build.
You can invoke the XSLT from a simple Powershell script using the .Net framework. My blog posts on EF (3.5) may help you to understand edmx processing.
