I am trying to do some SQL stuff with Entity Framework, using Visual Studio 2013 and C#.
My issue is that I am missing sevral templates from the "ADO.NET Entity Data Model" item in the template panel of my visual studio.
This is what I have :
And this is what I should get :
Any help would be much appreciated.
*I tried installing the latest version of the entity framework from NuGet, but it did not solve my issue

I am working on a C# project using Linq to query SQL server, want to tackle some performance issue with performance profiler, however facing 2 problems
The instrumentation launching Internet Explorer, any way to change the browser setting?
The Database option greyed out in my performance profiler, Microsoft said "The Database tool requires Visual Studio 2019 version 16.3 or later and a .NET Core project on Windows using either ADO.NET or Entity Framework Core."
And I am using version 16.11.19, and I am using Linq in my project, so I guess this project is using Entity Framework Core
Any work around to fix the above problems?
(I am using visual studio 2019 community version)
Within Visual Studio 2017 there is no ADO.net Entity model in 'Add New Item' menu?
It is available on previous versions of Visual Studio. What kind of solution can fix that problem?
I think if you are useing visual studio 2017, use ADO.NET Entity Data Model to use new facilities.
Visual Studio.NET 2017, ADO.NET Entity Data Model
I'm using Visual Studio 2017 and Entity Framework 6, and for the life of me, I cannot find the EDMX file, Entity Data Tools, Model Browser, or Entity Designer...
Am I losing my mind here? I've created multiple new projects trying to find these UI-based tools for working with the Entity Framework data models and can't seem to get anywhere.
Please help!
I believe I have the correct tools installed in the VS2017 Install:
For anyone looking at this, in my case the answer was that I was using a Code-First implementation of the Entity Framework, which apparently does NOT give you access to the Visual Tools.
So there is no EDMX file in Code-First Entity Framework.
I had similar issue. I reinstalled Entity Framework 6 tools without luck, even reinstalled SQL tools (sorry, forgot exact name). But solution was very simple:
right-click the edmx file-> choose Open with->choose ADO.NET Entity
Data Model Designer
At the installation of VS2017 you had to go to Individual Components to install those tools, don't think they are installed by default.
Individual Components
SDK, Libraries and Components
You can run this install from the VS Installer
Entity Framework not appearing in Add New Item list in Visual Studio 2017
Please also see the current documentation. They state that for current Visual Studio versions, the tools will be included. For previous versions, separate installers (MSI packages, not extensions) are available for download at the Microsoft Download Center. F.e., see Visual Studio Releases > Visual Studio 2013, which will tell you where to find the MSI for Visual Studio 2013.
As in response to gotmike's accepted answer, today there's an 3rd party marketplace extension called Entity Framework Visual Editor, which can be used (I didn't try it myself) to generate a visual representation out of the code first model/POCO classes.
Also note that the Entity Framework Power Tools always had the feature to preview code first entities in a designer view called "View Entity Data Model (Read-only)". This option appears in your context menu when you select a model class derived from DbContext.

how to fix this problem ?
Anyone having the same problem on any kind of project (like it was my case) and unable to open existing EDMX, be careful when you install VS 2015, and make sure to check the box saying "Microsoft SQL Server Data Tools".
I had not (we only use MySQL), and it is required for the Entity Framework designer, whatever connector you're using.
there is no support for edmx format in mvc6.
Pre version mvc5 would have got but mvc 6 doesnt.
Good luck
The image below describes my problem.
There is no option for MySQL Server although i have installed the MySQL connector for Visual Studio 2012.
I want to use Entity model and i am stacked here.
Any idea why is this happening?
You have to use MySQL for Visual Studio:

Because since version 6.7 MySql connector does not include anymore MySQL for Visual Studio integration
