    TransferJsonConverter

    A custom JSON converter library with some useful features for ASP.NET

    A custom JSON converter library with some useful features for ASP.NET client-server application. It serializes objects to a JSON string, using the provided interfaces as templates, and including attributed fields not included in the interfaces. This allows you to pass objects from the storage layer through the model to the client, hiding specific data, while still storing it for postback from the client. It deserializes a JSON string into objects, reusing existing objects as targets if possible. This avoids creating an intermediate list of objects when populating an ObservableCollection on the WPF client, and reduces the overhead of creating multiple objects in memory and the garbage collector.

    UpdateSharp

    A simple auto-updater built in C#.

    Ever needed an easy way to update your program without much code? Have a look at UpdateSharp. It consists of 1 DLL file, and 1 CSPROJ. Its super easy to use, and is fully automatic - your users don't need to do anything. So what does it do? Well, it checks the version of the application currently installed against the one on your webserver. If they aren't equal, the updater will run. Its lightweight, and takes just a few seconds to update the software (excluding download times). UpdateSharp is free, but I ask that you link back in your About box or something. I have an update planned, and it will happen soon :) If you get stuck, check the readme file.

    WPF Entity Validation Utils

    DataAnnotations & IValidatableObject Support for WPF

    WPF doesn't support DataAnnotations and IValidatableObject out of the box. This project fills this gap via adapters to the IDataErrorInfo interface which is supported by the WPF validation infrastructure. Your code becomes more DRY since DataAnnotations are supported by major MS technologies such as Entity Framework and ASP.NET MVC. At the top it defines a small internal DSL for defining validation rules that span multiple members (such as DateRange) that make those rules a no brainer. The project is not yet fully completed. Currently there is no flexibility to pass-through only some of the rules in a specific view or to change the error messages from a view. Feel free to participate and improve this project.
