1. In business logic layer I have create one method for get the records from database.
2. In ASP.NET web project using obj of above class I am calling that method in aspx.cs code behind.In aspx.cs code I am calling this reference using following name spaces

1.using System.Data.Entity;
2.using System.Data.Entity.Infrastructure;

I am adding reference both business logic layer & WEB PROJECT.In localhost system its working fine. while developing the application in live in causes error.I am getting following error.

The type or namespace name 'Infrastructure' does not exist in the namespace 'System.Data.Entity' (are you missing an assembly reference?)

Solution 4

Don't add Entity Framework library via "Add reference" dialog (it's old version) You need to add NuGet package "Entity Framework" of latest version.
