How to inherit from the DbContext Class

Multiple DbContext classes for a single web app. Good or bad?

Using multiple DbContext classes implies complicating cross-transactions (you can find a solution to this problem on the web here an example ...http://pastebin.com/YEDqyH0n...) but may be justified. It all depends on your architecture and the separation that you want to design....Anyways you should look at the Repository and UnitOfWork patterns to ...

Inherit a common base class in EF code first

Are you trying to create a table of EntityBase (Great blog post about this : ...Table Per Type Inheritence...) that all your entities share, or to simply create a base object so all your entities can use the same methods?

Separate POCO Object classes and DBContext from Entity Framework 6 Model

c# entity framework: correct use of DBContext class inside your repository class

I think you ...should not follow... the first article, and I will tell you why....Following the first approach you're loosing pretty much every feature that Entity Framework provides via the ...DbContext..., including its 1st-level cache, its identity map, its unit-of-work, and its change tracking and lazy-loading abilities.

New inherited class gets its property name renamed on migration with EF Code First

I think you'd be better off explicitly naming your ...Value... columns by using data annotations, rather than risking them being re-assigned during migration. For example:...public class IntegerProperty : ProductProperty { [Required] [Column("Value1")] public int Value { get; set; } } public class StringProperty : ProductProperty { ...

Add manual DbSet to Partial class DbContext EntityFramework

I use DataContext not DBContext and I always create my data classes like below.... [Table(Name = "AppSettings")] public class AppSetting { [Column(Name = "Id", IsPrimaryKey = true)] public Guid Id { get; set; } [Column(Name = "SettingName")] public string SettingName; [Column(Name = "SettingValue", UpdateCheck = UpdateCheck.Neve...

EntityFramework, Inherited Classes without Discriminator

If you dont have a discriminator or table for each class its not possible to distinguish your entities....You can actually omit the bool properties if you don't need them in your domain model, because Entity Framework uses Table per Hierarchy as default to map inheritance. It will automatically create a discriminator column for you. If you add a tr...

Insight into inheriting from a base controller class

Your login info should be in external config (user secrets, environment variables, Azure Key Vault, etc.) and you should then be injecting it into your controllers. The max results and page number should either also be in external config or provided as params to your action (if you want to be able to customize it via the request)....Create a class ...
