save changes using Breeze, web api, and entity framework

I am following John Papa's tutorial. When I edit speaker and save, I get following exception. I am very new to this. I really appreciate if someone can point me what I am missing. Thank you!

ExceptionMessage=Field not found: 'Breeze.ContextProvider.EntityInfo.AutoGeneratedKey'.
ExceptionType=System.MissingFieldException
StackTrace=   at System.Web.Http.ApiController.<InvokeActionWithExceptionFilters>d__1.MoveNext()

Right, you will need that update:

You can use the Package Manager Console and run the following line to CC.DataAccess project: PM> Install-Package Breeze.Server.ContextProvider.EF6

https://www.nuget.org/packages/Breeze.Server.ContextProvider.EF6

My regards
