ExtCore is free, open source and cross-platform framework for creating modular and extendable web applications based on ASP.NET Core. It is built using the best and the most modern tools and languages (Visual Studio 2015, C# etc). Join our team!

ExtCore allows you to decouple your application into the modules (or extensions) and reuse that modules in other applications in various combinations. Each ExtCore extension may consist of one or more projects and each project may include everything you want (as any other ASP.NET Core project). Controllers, view components, views (added as resources and/or precompiled), static content (added as resources) will be resolved automatically. These projects (extension pieces) may be added to the application directly as dependencies in project.json of your main application project (as source code or NuGet packages), or by copying compiled DLL-files to the Extensions folder. ExtCore supports both of these approaches out of the box and at the same time.

By default, ExtCore doesn’t know anything about data and storage, but you can use ExtCore.Data extension to have unified approach to working with data and single storage context. It supports Microsoft SQL Server, PostgreSql and SQLite, but it is very easy to add another storage support.

You can find more information using the links at the bottom of this page.

All you need to do to have modular and extendable web application is:

• add ExtCore.WebApplication as dependency to your main application project;
• inherit your main application’s Startup class from ExtCore.WebApplication.Startup;
• add ExtCore.Infrastructure as dependency to each of your extension projects;
• implement ExtCore.Infrastructure.IExtension interface for each of your extensions (optional);
• tell main application about the extension.

Please take a look at this sample.

You can also download our ready to use sample. It contains everything you need to run ExtCore-based web application from Visual Studio 2017, including SQLite database with the test data.
