  Ok, I removed the folder Auth from the Blog.Core module and added a reference to the MainApp.Core so that both use the same User, Role, etc.

  Now, when I run the application I get this exception. I went back to check the code for the blog module, there was an attribute on the Blog DbContext as follows:

  [AutoRepositoryTypes(
          typeof(ISampleBlogRepository<>),
          typeof(ISampleBlogRepository<,>),
          typeof(SampleBlogRepositoryBase<>),
          typeof(SampleBlogRepositoryBase<,>)
          )]
      public class SampleBlogDbContext : AbpZeroDbContext<BlogTenant, BlogRole, BlogUser>
  

  Maybe Framework has changed a lot since that blog module was created. But really, why is it that difficult to create a custom module and make the application moduler?

  "Can't create component 'MainApp.Blog.Posts.PostAppService' as it has dependencies to be satisfied.
  ↵
  ↵'MainApp.Blog.Posts.PostAppService' is waiting for the following dependencies:
  ↵- Service 'MainApp.Blog.Domain.Repositories.ISampleBlogRepository`1[[MainApp.Blog.Posts.Post, MainApp.Blog.Core, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]]' which was not registered.
  ↵"

  Now, when I re-use Blog.EntityFramework in a sense I set SetInitializer(null) so that only 1 DbContext creates tables, the rest will just use the existing tables.

  I then get this exception below.

  So dealing with separate modules is full of exceptions and spending lots of hours to make this work.

  Found more than one concrete type for given DbContext Type (Abp.Zero.EntityFramework.AbpZeroCommonDbContext`2[MainApp.Authorization.Roles.Role,MainApp.Authorization.Users.User]) define MultiTenancySideAttribute with Host. Found types: MainApp.EntityFramework.MainAppDbContext, MainApp.EntityFramework, Version=3.1.0.0, Culture=neutral, PublicKeyToken=null, MainApp.Blog.EntityFramework.MainAppBlogDbContext, MainApp.Blog.EntityFramework, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null.

  You don't need BlogTenant, BlogRole, BlogUser in AspNetZero. Remember, Hikalkan implemented that example on top of Boilerplate, not AspNetZero. AspNetZero already implements those items with the User and Role objects. Remember, AspNetZero is an implementation of Boilerplate, so it's a best practice implementation of that Idea. So, you just have to keep that in mind when you see examples on Boilerplate.

  So let's take this from his example:

  [Table("BlgPosts")]
      public class Post : FullAuditedEntity<int, BlogUser>
      {
          public const int MaxTitleLength = 128;
  

  In AspNetZero, you need to inherit just from FullAuditedEntity. Don't reference BlogUser.

  <a class="postlink" href="https://aspnetzero.com/Documents/Developing-Step-By-Step">https://aspnetzero.com/Documents/Develo ... ep-By-Step</a> (Pick your flavor from list)

  That step by step guide shows this when it talks about creating the People entity.

  Hope that points you in the right direction.

  Not sure what your goal is on the EF side. Maybe post the project you are trying to code and someone can help.

  Also, I have never had to implement AutoRepositoryTypes within AspNetZero. Not sure what that attribute is for. Someone else might need to chime in here and explain that one.

  My suggestion is do the AspNetZero walk through, and maybe avoid looking at anything on the Boilerplate side to learn AspNetZero. Maybe that's causing some confusion.

  Hi @drcgreece,

  Can you share your Blog module's DbContext definition ?

  Thanks.

  Hi,

  I have deleted your last post in this topic because sharing source code here is against license rules. Can you also delete files from dropbox as well ?

  Please share only your DbContext class's content here or you can send the whole project via email.

  Thanks.

  Hi @drcgreece,

  Your shared solution does not contain Blog.EntityFramework project. I think you added your entities to Main dbContext.

  I think the previous problem was causing by deriving your Blog dbContext from AbpZeroDbContext, it should be AbpDbContext.

  That is possible! I will check it out.

  If I want to make use of UserAppService in my Blog module, i can just use either property or constructor injector for IUserAppService and then I will be able to use that?

  Thanks
