ASP.NET Identity 2.0 Tutorial - Entity Framework Free


So in this post I detailed how to use Asp Identity with Entity Framework Database First. However when I started a new MVC project and tried to follow the steps nothing worked. ASP Identity 2.0 has ruined everything by introducing many breaking changes.

This post will guide you on how to setup Identity 2.0 without Entity Framework. The original post was a lot longer but I've tried to cut down a lot of the rambling, for a great step-by-step guide to Identity 2.0 see this excellent CodeProject post by John Atten.

Create a New Project

Let's create a new MVC project using Individual User Accounts as shown below to see what the template gives us:

The default new project screen.


Minify Json using JSON.NET


In my current project I'm using Json stored in the SQL Server database to replicate the storage capability of the browser Session but allowing the data to persist on the user reloading/leaving the page.

One of the challenges is to store the serialized object in as few characters as possible while preserving meaning.

Without touching the settings, Json.Net stores the strings without extraneous whitespace, but even serializing a fairly small aggregate object can use a lot of characters.This post details a couple of the features I've used to minimise the number of characters.

Store Booleans as Integers in Json

JSON.NET supports custom conversions using a class which inherits from JsonConverter:

public class BooleanConverter : JsonConverter
    public override bool CanConvert(Type objectType)
        return typeof(bool).IsAssignableFrom(objectType);

    public override void WriteJson(JsonWriter writer,
        object value, JsonSerializer serializer)
        bool? source = value as bool?;
        if (source == null) { return; }

        int valueAsInt = ((bool)source) ? 1 : 0;


    public override object ReadJson(JsonReader reader, Type objectType,
        object existingValue, JsonSerializer serializer)
        bool returnValue = (Convert.ToInt32(reader.Value) == 1);

        return returnValue;

This converter will store booleans as 1 and 0 rather than true and false; this saves 3 and 4 characters respectively.

Shorten Field and Property Names

By using the built in [JsonProperty("Name")] we can save space in the serialized object. If we define one letter aliases for our properties we save a lot of space, especially when serializing an array of objects:

public bool IsAThing { get; set; } 

If the full object has IsAThing = false the string representing the serialized object stores this as "b":0 which is the shortest representation possible (unless you set the default value to false and only serialize where the boolean value is true).

Serializing an HtmlString

This isn't a space saving tip but where you need HtmlStrings to be serialized and deserialized you can use the converter below:


Simple Introduction to MVC Ajax (Post 3)


Now we have partial views loading forms using Ajax and we can call controller methods using Ajax it's time to put everything together.

A picture of a cat.

We're going to start with a blank scenario to make it easier to follow. This makes this a very long post but it puts together everything we learned.

I managed to coerce PHP into creating a new route on my website. You can see the full code for the classes/views in this demo as follows:
