It intelligently runs automated tests so that you don't have to, and gives you a huge amount of useful information about your tested code, such as code coverage and performance metrics, inline in your IDE while you type.

PostSharp is the #1 pattern-aware extension to C# and VB. It allows developers to eradicate boilerplate by offloading repeating work from humans to machines. PostSharp contains ready-made implementations of the most common patterns and gives you the tools to build automation for your own patterns. Developers usually think in terms of design patterns, but with conventional programming languages, they end up writing boilerplate code. PostSharp extends the C# and VB languages with a notion of pattern. The result: shorter, cleaner code that’s easier to write and understand, contains fewer defects and is less expensive to maintain.

Wisej provides a platform and set of tools designed to ease the burden of developing, testing, deploying, and maintaining complex business software. It bridges the gap between traditional WinForms-style desktop applications and the web by empowering developers to leverage their existing .NET and C# skills. Developers are able to use the tools they are familiar with, like a pixel-perfect design surface and drag-and-drop controls with the languages they are comfortable with (C# or VB.NET) to build real-time web applications without having to learn HTML, CSS, or jаvascript. They can stay in their favorite IDE like Visual Studio to take advantage of features like IntelliSense, integrated debugging, design surfaces and source control integration. Front-end developers can leverage their knowledge of web technologies to augment applications and seamlessly integrate third-party packages like HTML5 charting libraries and ASP.NET controls.
