    DotNetOpenServer SDK

    DotNetOpenServer SDK

    Lightweight fully extendable client/server application framework

    DotNetOpenServer SDK is an open source lightweight fully extendable TCP socket client/server application framework enabling developers to create highly efficient, fast, secure and robust cloud based smart mobile device and desktop applications. Why? Unlike most application server frameworks, which are implemented over slow inefficient stateless protocols such as HTTP, REST and SOAP that use bulky ASCII data formats such as JSON and XML, DotNetOpenServer has been built from the ground up with highly efficient stateful binary protocols.

    Duality

    Duality

    a 2D Game Development Framework

    Duality is a plugin-based 2D game development framework based on C# and OpenTK. To get a quick overview, please visit the project page. Duality is a modular 2D game engine that provides its own visual editor. It's highly extensible, written entirely in C# and backed by OpenGL. For a lot of game libraries, your code has the active role of setting everything up and managing it. These roles are reversed here: Your primary job is to define objects and specify their behaviors, Duality can handle all the rest. Drag files into the editor and drag assets into the game. Type C# code for game logic and engine extensions. Add bits of your code to objects in the game. Duality is being constantly developed since 2011, let's build some great games with it. Modified Assets are automatically reloaded. Write code and test it directly without restart.

    Electron.NET

    Electron.NET

    Build cross platform desktop apps with ASP.NET Core

    Build cross-platform desktop apps with .NET 5 and ASP.NET NET Core (Razor Pages, MVC), Blazor. Electron.NET is a wrapper around a "normal" Electron application with an embedded ASP.NET Core application. Via our Electron.NET IPC bridge we can invoke Electron APIs from .NET. The CLI extensions host our toolset to build and start Electron.NET applications. There are lots of different approaches how to get an X-plat desktop app running. We thought it would be nice for .NET devs to use the ASP.NET Core environment and just embed it inside a pretty robust X-plat environment called Electron. Porting Electron to .NET is not a goal of this project, at least we don't have any clue how to do it. We just combine ASP.NET Core & Electron. The current Electron.NET CLI builds Windows/macOS/Linux binaries. Our API uses .NET 5, so our minimum base OS is the same as .NET 5.

    Entity Framework 6

    Entity Framework 6

    This is the codebase for Entity Framework 6

    Entity Framework 6 (EF6) is a proven object-relational (O/RM) mapper for .NET with many years of feature development and stabilization. Like O/RM, EF6 reduces the impedance mismatch between the relational and object-oriented worlds, allowing developers to write applications that interact with data stored in relational databases with strongly typed .NET objects that represent the domain of the database. application, and eliminate the need for much of the data access "mechanical" code that you would normally write. Mapping POCO entity classes that do not depend on any EF type. Models can be generated from existing databases and then manually edited, or they can be created from scratch and then used to generate new databases. Integration with .NET Framework application models, including ASP.NET, and through data binding, with WPF and WinForms. Database connectivity based on ADO.NET and various providers available to connect to SQL Server, Oracle, MySQL, SQLite, PostgreSQL, DB2, etc.

    Entity Framework Plus

    Entity Framework Plus

    Entity framework plus extends your DbContext with must-haves features

    Entity Framework Plus extends your DbContext with must-haves features, include filter, auditing, caching, query future, batch delete, batch update, and more. Deleting using Entity Framework Core can be very slow if you need to delete hundreds or thousands of entities. Entities are first loaded in the context before being deleted which is very bad for the performance and then, they are deleted one by one which makes the delete operation even worse. EF+ Batch Delete is the most efficient way to delete records. You drastically improve your application performance by removing the need to retrieve and load entities in your context and by performing a single database roundtrip instead of one for every record. Deletes multiples rows in a single database roundtrip and without loading entities in the context. Updates multiples rows using an expression in a single database roundtrip and without loading entities in the context.

    EventFlow

    EventFlow

    Async/await first CQRS+ES and DDD framework for .NET

    Async/await first CQRS+ES and DDD framework for .NET. Designed with sensible defaults and implementations that make it easy to create an example application. EventFlow uses interfaces for every part of its core, making it easy to replace or extend existing features with custom implementation. To get a more complete example of how EventFlow could be used, have a look at the shipping example found here in the code base. The example is based on the shipping example from the book "Domain-Driven Design - Tackling Complexity in the Heart of Software" by Eric Evans. Its in-progress, but should provide inspiration on how to use EventFlow on a larger scale. If you have ideas and/or comments, create a pull request or an issue. The aggregate ID in EventFlow is represented as a value object that inherits from the IIdentity interface. You can provide your own implementation, but EventFlow provides a convenient implementation that will suit most needs.
