How do I clear this.

error CS0266: Cannot implicitly convert type 'System.Collections.Generic.List<<anonymous type: string Name>>' to 'System.Collections.Generic.IEnumerable<System.Collections.Generic.List<ProductsApi.Models.Product>>'. An explicit conversion exists (are you missing a cast?)

What I have tried:

public  IEnumerable<IGrouping<String,Product>> GetProducts4()
        {
            var group =(from p in _context.Products
                        group p by p.Name
                        into g
                    select new 
                    {
                        Name = g.Key
                    }).ToList();
            return group;
        }

You are returning a List<String> from a method that is supposed to return an IEnumerable<IGrouping<String,Product>>.

If you have another question, then post a new question.

Editing your existing question to completely change what you're asking is just rude.

Simple: don't project the group before returning it. (You are currently only selecting the group's key, which doesn't match your return type.)

C#

public  IEnumerable<IGrouping<String,Product>> GetProducts4()
{
    return from p in _context.Products
           group p by p.Name into g
           select g;
}
