SteelHtml

SteelHtml is an open-source HTML template engine for.NET applications. It was created by Martin Schröder and first released in 2009. SteelHtml is designed to separate the view layer from the business logic, allowing developers to create dynamic and maintainable web applications.

SteelHtml templates are written in HTML, with additional syntax for dynamic data binding, conditional statements, and other features. The engine uses a scoping mechanism to handle template inheritance and overlapping block elements. It also supports the use of global variables and the access to sensitive state objects, like the request object.

SteelHtml is known for its compact syntax, consistent and easy to read templates, and the possibility of easily transform HTML output to other formats like JSON. The engine also has built-in support for common web controls, making it easier to interact with the presentation layer.

SteelHtml supports ADO, NHibernate and any other Repository pattern implementation out-of-the-box, making it suitable for use in web applications with complex data models. Also, It supports postbacks, returnUrl, and current culture mechanisms, helping developers solve common web-related issues.

The project has been actively maintained since its release and has gained attention from a community of developers. Although it's not as widely used as some other template engines, SteelHtml is still considered a robust and reliable tool for creating web applications. Developer can take advantage of its ease of use and versatility.
