Я установил dotnet ef
инструмент для генерации миграций для базового проекта do tnet, над которым я работаю с помощью команды. dotnet tool install -g dotnet-ef
. Установка прошла успешно. Для нас dotnet ef
я установил пакеты nuget ниже
- Microsoft.EntityFrameworkCore.SqlServer
- Microsoft.EntityFrameworkCore
- Microsoft.AspNetCore.Identity.EntityFrameworkCore
- Microsoft.EntityFrameworkCore.Tools
При попытке сгенерировать миграции с помощью команды dotnet ef migrations add IdentityandCategory
я получаю вывод ниже.
It was not possible to find any compatible framework version
The framework 'Microsoft.NETCore.App', version '3.1.1' was not found.

You can resolve the problem by installing the specified framework and/or SDK.
The specified framework can be found at:

Я переустанавливаю do tnet 3.1.1 но эта проблема продолжается. dotnet info
, кажется, обнаруживает версию при запуске donet --info
