Calcium is a project by Daniel Vaughan and Katka Vaughan

Calcium for Windows Phone

Calcium for Windows Phone is a consolidation of the infrastructure code that has been written for the book Windows Phone 7.5 Unleashed, and is already used by a number of published apps. Calcium for Windows Phone is a light weight framework for incorporating the main features that every app needs. Unlike Calcium for WPF and Silverlight, Calcium for Windows Phone does not depend on Prism and has a smaller footprint, more suitable for the mobile platform.

Some of Calcium for Windows Phone features include:
  • A user options system that allows you to add a settable option to an options page, with a single line of code.
  • A bindable application bar with toggle buttons and menu items, hyperlink button/menu items, which allows you to host multiple application bars in a Pivot.
  • Built-in support for localization. Bindable resources allows the user to change the interface language at run-time.
  • An IoC container and DI infrastructure, and templates to allow you to hide or show a Purchase link in your app depending on the • Trial state of your app and so forth.
  • Templates for Views with ViewModels.
  • Attribute based state persistence system.
  • Message service that allows you to display messages and ask the user questions from your ViewModel.
  • Launchers and Choosers abstraction layer.
  • Input Validation system, with styles customized for displaying validation errors.

Calcium for WPF

Calcium for WPF consists of a client application and server based WCF services, which allow interaction and communication between clients. Out of the box, Calcium comes with a host of modules and services, and an infrastructure that is ready to use in your next application.

The following is a list of just some of the features of Calcium for WPF:
  • Visual Studio templates for instantly creating Calcium projects, including client applications, MVVM Module Templates, and server WCF host projects. (C# and VB.NET!)
  • Module Manager for enabling or disabling of modules at runtime.
  • Theme Support (with two themes included)
  • Duplex messaging services for interacting with the user from the client or server using the same API. Interact with the user using Message Boxes from the server!
  • A Command Service to associate WPF ICommands with content interfaces that only become active when an active view or viewmodel implements the interface.
  • Region Adapters for ToolBars and Menus.
  • Client-server logging ready to work out-of-the-box.
  • Includes modules, such as a Web Browser, Text Editor, Output Window, and many more.
  • Tabbed interface with dirty file indication (reusable across modules).
  • A User Affinity module that assists collaboration with other users of the application.
  • Undo/Redo/Repeat task management system.
  • And many more!
