Generic Repository Pattern in ASP.NET Core

I had to run extra configuration In addition to author's instruction
1. In nuget package manager console I ran "dotnet restore"
2. At the end, I opened applicationhost.config and changed the physical path point to my project location. eg. <virtualDirectory path="/" physicalPath="C:\xxx\Generic Repository Pattern in ASP.NET Core\C#\GR.Web" />
It worked for me. Hope this can help others who had the same problem like me.
Thank you Sandeep, this is so beautiful code.

I have a question: did you create a model and also create a model map manually? Because I see this pattern first time, could you tell me why did you use this pattern? Thanks.

Thanks Tiger Jin,These steps are awesome.I have an article for detail description. https://social.technet.microsoft.com/wiki/contents/articles/36510.asp-net-core-generic-repository-pattern.aspx 

Hi, I'm trying to implement your repository within my web project. I have a models folder where all the table classes DBContext and repositories are situated. I also added a BaseEntity class inwhich all my table classes inherit from. Now when I invoke my controller where I have instantiated the link to the Repository for my "User" class I get the following error thrown back from .net core:

"InvalidOperationException: Unable to resolve service for type 'NetCoreAngular2.Models.IRepository`1[NetCoreAngular2.Models.User]' while attempting to activate 'NetCoreAngular2.Controllers.SampleDataController'."

Do you have any idea what could be causing this?

Thank you

IMHO you should change solution name from "GenericReposotory.sln" to "GenericRepository.sln"

Here is the error I get:

Thanks Sandeep;

Changing the port # on GR.Web solved the problem.

Forgot to mention, nice work Sandeep.

Glad to see your problem solved. Thanks for the feedback!
