How to Configure a Self Referencing Entity in Code First

By rcjkierkels in C# / ASP.NET 3rd April 2015 3 Comments

Recently I was working on a project that required a categorization option. I wanted the user to have the option to create categories and as many subcategories as they wanted. To realize this I created a category model that was self referencing:

public class Category
{
        public int Id { get; set; }
        public string Name { get; set; }
        public int? ParentId { get; set; }
 
        [ForeignKey("ParentId")]
        public virtual Category Parent { get; set; }
}

public class Category

{

public int Id { get; set; }

public string Name { get; set; }

public int? ParentId { get; set; }

[ForeignKey("ParentId")]

public virtual Category Parent { get; set; }

}

URL Rewriting in EPiServer 6

By rcjkierkels in C# / ASP.NET, EPiServer 26th November 2014 0 Comment

Today I was working on a project that uses EPiServer version 6. As you probably know EPiServer 6 is still using webforms, not MVC. For SEO optimalisation we needed to rewrite incoming URL’s to make them uniform. For example all these URL’s should go to the same page

/en/Some-Interesting-Page
/Some-Interesting-Page
/en/some-interesting-page

For SEO it is important that there is only one valid URL. Other URL’s should throw a statuscode 301 and redirect to the correct url. For this I needed to do some URL rewriting in EPiServer.
