In particular, Helios projects do not support. But, they do not attempt to “provide 100% compatibility with existing applications. Beside that, their goals are to provide “higher density on web servers”, “behavior that mimics self-host more than it mimics web-host” and to “reduce the friction of deploying a web application,” according to Levi Broderick, a security engineer working on ASP.NET. The idea behind Helios is to provide a runtime that is based on the mature and feature rich environment provided by IIS but without the legacy ASP.NET attachments. ASP.NET interaction only kicks in if ASP.NET modules or handlers are installed and those are comparatively slow when compared to the native core and native modules. Keep in mind that although IIS and ASP.NET are closely tied together, the IIS core itself is a fairly lightweight and runs entirely in native code. … Helios is a very light-weight and short circuited version of a Web host bootstrapped on top of raw IIS. It runs entirely outside of the stock ASP.NET Http Runtime environment, bypassing the module pipeline and default ASP.NET runtime processing. Helios doesn't use System.Web and directly hooks into IIS's native interfaces to provide to base OWIN interfaces and context semantics. Helios is a web runtime that runs on IIS, but not the full blown web server from Microsoft, as Rick Strahl explained: Not only that, but developers can deploy such web applications on custom OWIN hosts or on Katana, which is a reference OWIN implementation. ![]() In order to make the development of web tools more agile and responsive, the ASP.NET team has created a number of smaller components – ASP.NET MVC, ASP.NET Web API – which do not depend on, have a much faster development cycle, and fixes can be provided on a timely manner.
