I have made .net core 2.0 web app. I have added Entity Framework 6.2.0 using NUGET and then I get this error
Package 'EntityFramework 6.2.0' was restored using '.NETFramework,Version=v4.6.1' instead of the project target framework '.NETCoreApp,Version=v2.0'. This package may not be fully compatible with your project.
How do I fix this?
The problem is your entity version is confused with
.NetCore. Your application target framework is
Asp.Net Core. So You should install package related with
In your case
'EntityFramework 6.2.0' is supports by
.NETFramework,Version=v4.6.1' not by
'.NETCoreApp,Version=v2.0'. So use this below version of entity framework instead of yours.
PM> Install-Package Microsoft.EntityFrameworkCore -Version 2.0.1
Alternatively you can change your target framework to net461 as below.
By changing your target framework to net461 makes you available to use .net core and full .net frameworks. I think that for this period of time, this approach is better. Because EF Core still hasn't got some main features like many to many relationship and some others. Sure it depends on your needs and expectations from an ORM tool.
