Visual Studio 2019 Entity Framework Enable Migrations Error

I have a small ASP.NET web application, but for some reason I have an issue with migrations after type in Package Manager console:

PM> Enable-Migrations

Console throws this error

Enable-Migrations : Cannot bind argument to parameter 'Path' because it is null.
At line:1 char:1
+ Enable-Migrations
+ ~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidData: (:) [Enable-Migrations], ParameterBindingValidationException
+ FullyQualifiedErrorId : ParameterArgumentValidationErrorNullNotAllowed,Enable-Migrations

I use Visual Studio 2019 and have installed Entity Framework 6.3.0 via NugGet Package Manager. Also have a DbContext class in my models folder

I've tried a lot of solutions that I saw other people have made, but none of them works. Hope someone has similar problem.

P.S Project structure is

Project
    - Connected Services
    - Properties
    - References
    - App_Data
    - App_Start
    - Content
    - Controllers
    - fonts
    - Models
    - Scripts
    - Views
    - favicon.iso
    - Global.asax
    - packages.config
    - Web.config

Olá, Eu tive esse mesmo problema em um projeto pessoal, e após algumas horas de teste consegui resolver da seguinte forma: 1 - Acesse Ferramentas > Gerenciador de pacotes do NuGet > Gerenciador de pacotes do NuGet para solução.

2 - Desinstale o EntityFramework 6.3.0 "que foi o meu caso", e instale a versão 6.2.0, feito isso, Recompilar Solução, em seguida rode o comando > Enable-Migrations

Enable Migration success
