Hello Hans

It sounds like you should use an EPiServer Initialisation module for this:

It might also be worth checking for the existence of the category before inserting it to avoid any issues.

I'm using following fragment to create new categories from code (keep in mind that code will execute *every* time app pool will start - so you should take care of avoiding multiple creation of the same category):

namespace MyProject.Web.Initialization
{
    [InitializableModule]
    [ModuleDependency(typeof(InitializationModule))]
    public class CategorySetup : IInitializableModule
    {
        public void Initialize(InitializationEngine context)
        {
            CreateIfNotExists("Key", "Display Name", 1);
        }

        public void Uninitialize(InitializationEngine context)
        {
        }

        public void Preload(string[] parameters)
        {
        }

        private void CreateIfNotExists(string name, string description, int order)
        {
            if (string.IsNullOrEmpty(name))
            {
                throw new ArgumentNullException("name");
            }
            if (string.IsNullOrEmpty(description))
            {
                throw new ArgumentNullException("description");
            }

            var categories = CategoryList.LoadCategories();
            if (categories.Contains(name))
            {
                return;
            }

            var category = new Category(name, description)
                           {
                                   Available = true,
                                   Parent = Category.GetRoot(),
                                   SortOrder = order
                           };

            category.Save();
        }
    }
}
