Question

public class SomeRepository<TContext> : IDisposable
            where TContext : DbContext, new()
        {
            protected TContext context;
            protected SomeRepository()
            { }

        public virtual void Create<T>(T item) where T : class, new()
        {
            ...
        }
    }

    internal class SomeCrud : SomeRepository<SomeContext>
    {
        public override void Create(Product item)
        {
            ....
        }     
    }

}

I got error on public override void Create(Product item) not suitable method found to override.Please somebody see the mistake?If I’m writing like this:

        public override void Create<Product>(Product item)
        {
            ....
        }

I can’t see a Product type
Thanks

I think you are looking for this solution:

public class SomeRepository<TContext, T> where TContext : DbContext where T : class, new()
{
    public virtual void Create(T item) { }
}

internal class SomeCrud : SomeRepository<SomeContext, Product>
{
    public override void Create(Product item) { }
}

You actually should define the constraints of the product in the generic definition.
Note the T in SomeRepository<TContext, T>

You can try

    public void Create<T>(T item) where T : Product
    {           
    }

but why then use generics?
