Answer 1

I had this problem and none of the previous solutions helped me. My problem was actually due to an outdated version of powershell on my Windows 7 machine - once I updated to powershell 5 it started working.

I just had this problem too. I closed and opened VS2015 and it "fixed" the issue...

Answer 3

I ran into the same issue. Most of my projects had the same thing in tools.

"tools": {
    "Microsoft.EntityFrameworkCore.Tools": "1.0.0-preview2-final"
}

This worked fine on all but one project. I changed the entry in tools to

"tools": {
    "Microsoft.EntityFrameworkCore.Tools": {
    "version": "1.0.0-preview2-final",
    "type": "build"
  }
}

And then ran dotnet restore. After the restore completed, Add-Migration worked normally.

Answer 4

It's so simple.

Just install Microsoft.EntityFrameworkCore.Tools package from nuget:

Install-Package Microsoft.EntityFrameworkCore.Tools -Version 3.1.5

You can also use this link to install the latest version: Nuget package link

.NET CLI command:

dotnet add package Microsoft.EntityFrameworkCore.Tools

I tried doing all the above and no luck. I downloaded the latest .net core 2.0 package and ran the commands again and it worked.

Answer 6

Go to package manager console(in visual studio) and execute below command
