ExtCore allows you to build your web applications from the different independent reusable modules or extensions. Each of these modules or extensions may consist of one or more ASP.NET Core projects and each of these projects may include everything you want as any other ASP.NET Core project. You don’t need to perform any additional actions to make it all work: any ASP.NET Core project can be used as an ExtCore-based web application extension by default. Controllers, view components, views (added as resources and/or precompiled), static content (added as resources) are resolved automatically. These projects may be then added to the web application in two ways: as direct dependencies (as source code or NuGet packages) or by copying compiled DLLs to the Extensions folder. ExtCore supports both of these options out of the box and at the same time. Furthermore, any project of the ExtCore-based web application is able to discover the types that are defined inside all the projects (optionally using the predicates for assemblies filtering) and to get the implementations or instances of that types.
