How to remove project dependency from EntityFramework?

Question

ASP.NET

Hello!
There is an access layer with the given App.Data and an App.WebUI (MVC) presentation layer, the EntityFramework is used in the App.Data layer. Trying to use a class from App.Data where DbContext is used says:
" No Entity Framework provider found for the ADO.NET provider with invariant name 'System.Data.SqlClient'. Make sure the provider is registered in the 'entityFramework' section of the application config file.."
as I understand it, you need to connect it to App.WebUI EntityFramework, but how to remove this dependency?

Answer 1

Don't use Entity Framework. DbContext from EF.

Answer 2

Why remove addiction? It is better to prescribe the necessary lines in the config.

<configSections>
<section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
</configSections>
<connectionStrings>
<add name="ConnectionName"
         connectionString="Server=serverName;Database=DataBaseName; User ID=UserName;Password=Password;" providerName="System.Data.SqlClient" />
</connectionStrings>
<entityFramework>
    <defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlConnectionFactory, EntityFramework" />
    <providers>
      <provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" />
    </providers>
  </entityFramework>
