Ever felt like seamlessly calling C# from PHP or vice versa? Compiling PHP projects to a DLL and referencing them from a .NET app? Debugging and profiling your app at design time in Visual Studio? Or maybe distributing entire PHP apps as source-less, compiled and securely signed NuGet packages? PeachPie.io allows you to do all of those and more. It's a PHP compiler and runtime under .NET. In this talk we'll explain how it works, why it might be useful and we'll demonstrate how even the largest and most popular PHP projects, e.g. WordPress, MediaWiki or Laravel, can be run on .NET.
