- I installed "Microsoft.EntityFrameworkCore - 3.0.0;"
- I run the command: PM> Scaffold-DbContext" Server =. \ SQLEXPRESS1; Database = SCHOOLDB.MDF; Trusted_Connection = True; " Microsoft.EntityFrameworkCore.SqlServer -OutputDir Models

- I get an error: The name" Scaffold-DbContext "is not recognized as the name of the cmdlet, function, script file, or executable program.

Answer 1

I had the same problem today and I am using Windows 7. Windows 7 uses powershell 2.0 so I upgraded it to 5.1, you can upgrade it from here - https://docs.microsoft.com/en-us/powershell/scripting/install/installing-windows-powershell?view=powershell-6

Upgrading this solved my problem. I found this solution from here - https://github.com/aspnet/AspNetCore.Docs/issues/14863

Answer 2

Upgrade Powershell to 5.1

This is the link from where you can download according to your system requirement.

I have had the same error, everything was correct and there was no problem with the packages, nor problems with PowerShell. What happened was that I copied the script that I had done before from GitHub and pasted it into the Visual Studio package management console, without knowing that when I copied this from GitHub I copied a strange character that was invisible in the console, but which was causing the error.

Be careful when copying and pasting code or scripts because this can happen to you.
