Package Installation Error - Entity Framework

Question

The error occurs when I'm trying to create ADO.NET Entity Data Model. The error says:

The preinstalled packages have a reference to a missing Registry value. Could not find a Registry key with name 'EntityFrameworkVisualStudio14Tools' under 'SOFTWARE\NuGet\Repositoty'.

I'm using Windows 10, Visual Studio 2015, and tried to install Entity Framework 6.1.3

Answer 1

In my case the string EntityFrameworkVisualStudio15Tools was missing but instead EntityFrameworkVisualStudio16Tools was there. I guess because I also installed Visual Studio 2019, but I'm currently working in Visual Studio 2017. Registry Path on a 64 bit Windows:

HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Nuget\Repository

Solution: I created the string EntityFrameworkVisualStudio15Tools and copied the value from EntityFrameworkVisualStudio16Tools which was in my case:

C:\Program Files (x86)\Microsoft Visual Studio\Shared\Entity Framework Tools\NuGet Packages\
