I m doing work on edmx with database first development in MVC
But i got this error now.
Entity Data Model Designer is unable to display the file you requested
You can edit the model using the XML editor.
I searched on google also,but no use.
Anyone knows how to resolve it.
Thanks in advance.

From your description, I create a .edmx file in my application, it could be open with the Entity Designer.
Then I open it with xml editor, the header of my edmx file like below:
<?xml version="1.0" encoding="utf-8"?>
<edmx:Edmx Version="3.0" xmlns:edmx="http://schemas.microsoft.com/ado/2009/11/edmx">
<!-- EF Runtime content -->
<!-- SSDL content -->
If I replace "http://schemas.microsoft.com/ado/2009/11/edmx" with "http://schemas.microsoft.com/ado/2008/10/edmx".
next, I press control +s to save it, then, I close it.
when I open it with the Entity Designer again, it show me with the following:
if change back, it will show me correctly.
