Umbraco 8

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.
