Missing ADO.NET entity data model template from Visual Studio 2012 Professional. I don\'t even have \"Data\" category from Visual Studio template category.
I modifi
Close Visual Studio and then install "Entity Framework Tools for Visual Studio" from this location:
► [Visual Studio Disk or installer folder]\packages\EFTools\EFTools.msi"
I do it and I got the result.
You can also download this tool from here.
I solved this by going into project properties and changing the target framework. In my case, the default target framework for the project was 2.0 (no idea why - I would've expected 4.5 to be the default). I changed it to 4.5 and I was able to see the "ADO.Net Entity Data Model" option. I think it's all about having the correct EF tools installed for the CLR version that you are targeting.
I found the EFTools.msi file in my packages folder, and run it then choose uninstall then run it again and choose install. After this reinstall, the template appeared.
When you click on add new item you will get general list of templates. "Visual c# " may be highlighted on left had side menu when you open it. From that you must click on "Data" menu. Now you can see ADO.NET Entity Data Model :)
I did a search in C:\ProgramData\Package Cache for "eftools.msi"
There were three versions (from different beta/RCs I guess)
I picked the most recent and installed it.
This solved the problem for me.
It succeeded me in a way just downloaded from given link https://www.microsoft.com/en-in/download/details.aspx?id=40762 and run for repair the Entity framework.
