Custom model validation in ASPNET Core

I just wanted to post how to do custom model validation. It took me a few hours and it wasn't posted anywhere yet. So, I wanted to do my own model validation so I can call ModelState.IsValid and get whether the posted model was valid or not. I needed some custom code. In my case it was to make sure that only 1 of 2 boolean properties were set to true. After digging through the sources I found an easy way. Implement the System.ComponentModel.DataAnnotations.IValidatableObject interface. The def

ASP.NET vNext Custom Authentication

Converting non MVC3 projects to MVC3 projects

Well, I needed to do this because the project that the codgen tool in Orchard creates is not an MVC3 project. Call me picky, but I like the Add Control, Goto View, Create View, and all the other cool little things that come with an MVC project in Visual Studio. So, I set out to figure out how to do it. It's pretty easy, in the .csproj file, there is a project type GUIDs element. Starts out as something like this: <ProjectTypeGuids>{fae04ec0-301f-11d3-bf4b-00c04f79efbc}</ProjectTypeGuids> just
