I am using visual studio 2019 Ent and EntityFramework.6.4.4.
Whenever I'm restarting my VS19 and going to access EF it gives me the following error with code first approach.

What I have tried so far:
I found one temporary solution that by reinstalling every time nugete package i.e entity framework and it works.
But this is annoying and definitely not the solution. Looking for a permanent solution.
Thanks in advance.
In my case I was executing the
Add-Migration
command. Instead, I used
EntityFramework6\Add-Migration
And I had no more errors. (Thanks to this answer I found https://stackoverflow.com/a/58951090/2546759)
Another thing which did the trick was:
Make sure that all projects in the solution are using same EF version.
Restart Visual Studio.

Here is what you should do:
Download the project from your Google drive
Open in Visual Studio
Run Database-Update (Make sure the Entity Framework project is selected in the Nuget Package Manager.
That is all you need to do to get. All you will lose is the data in your previous database on the unavailable machine.
Best solution is to create a repo in Git, add you project in it. On there PC run git clone on the desired path.
Refer Setting up git repo

Delete all the folders inside the "packages" folder in your application folder. Then try to reinstall web grease from nuget. See if that solves your issue.
