Missing browser and diagram model of EDMX Visual Studio 2015

Question

I recently updated Visual Studio 2015. I opened my solution and worked. Until I decided to add an object to my edmx. So I double-clicked on the edmx file to open the diagram, at least, or maybe at least in the model browser, but it only opens the XML page. I checked the missing setup setup, but found nothing about the entity infrastructure. I tried to create a test solution and create another edmx, but the ADO.NET object is also missing. What's happening? Am I going to return to Visual Studio 2013?

Answer 1

For me, the sequence was:

• .edmx
• " "

XML, , XML Text Editor edmx. , ADO.NET Entity Data Model Designer

• edmx

• " " , .
