    Register dbContext through composition

    I want to use the Microsoft.EntityFrameworkCore.dbContext into the controller.

    I would really appreciate if I can get to know how we can register dependency for that in:

    public class Global : UmbracoApplication, IComposer
        {
            public void Compose(Composition composition)
            {
                composition.Register<IRepository1, Repository1>();
                // want to register dbContext here with so that I can use it like mentioned in section 2
    
            }
    

    Section2

      public class Repository1 : IRepository1
        {
            private SomeDbContext _context;
    
            public Repository1(SomeDbContext dbContext)
            {
                _context = dbContext;
            }
    }

    Hi kapil,

    That should not be that difficult. Give it a try with:

    composition.Register(typeof(SomeDbContext));
    

    or

    composition.Register<SomeDbContext>(factory => new SomeDbContext(), Lifetime.Scope);
    

    in your component.

    Instead of implementing the IComposer interface you should implement the IUserComposer interface.

    It is good to know that Umbraco 8 uses LightInject for DI, so you can search the www for specific scenarios with LightInject. https://www.lightinject.net/

    You can also take a look at https://github.com/umbraco/Umbraco-CMS/blob/977bf91409a7965519c0504228cc68b11c6ca5c6/src/Umbraco.Web/Runtime/WebInitialComposer.cs to see different ways you can register stuff.
