    ASP.NET Core API Endpoints

    ASP.NET Core API Endpoints

    A project for supporting API Endpoints in ASP.NET Core web apps

    It is a lightweight library that promotes building web APIs using a feature-focused endpoint pattern instead of traditional controller-based architecture. The project encourages developers to create small, single-responsibility endpoint classes that improve code clarity, testability, and maintainability in modern applications. It provides base classes and conventions that reduce boilerplate while keeping full compatibility with standard core middleware, routing, and dependency injection. The approach aligns well with vertical slice architecture and clean architecture principles, helping teams organize APIs around use cases rather than technical layers. ApiEndpoints is designed to remain minimal and non-intrusive so developers retain full control over their application structure. Overall, it serves as a productivity-focused architectural helper for building clean and scalable core APIs.

    BaGet

    BaGet

    A lightweight NuGet and symbol server

    BaGet (pronounced "baguette") is a lightweight NuGet and symbol server. It is open-source, cross-platform, and cloud-ready! You can also use the BaGet.Protocol package to interact with a NuGet server. Cross-platform, dockerized, cloud-ready, supports read-through caching. Can index the entirety of nuget.org. Coming soon, support for private feeds. You can run BaGet on your preferred platform, on your computer, Docker, Azure, AWS, Google Cloud, and Alibaba Cloud (Aliyun). With a few extra steps, you can run BaGet behind a Windows IIS proxy. This has many benefits, including automatic restarts on reboots. You may need to give special permissions to the top-level BaGet folder so that the app can persist in its state. This is necessary as the Application Pools' identity is a virtual account that isn't recognized by the Windows User Management Console.

Though the features are not what you would expect from a program written and sold by a corporation, you may find it an entertaining tool Also notice that no installation is required, meaning it will not put annoying icons on your desktop and start menu, and you are free to delete it at will. If you know coding, be sure to check out the source code, which is in the form of a zipped-up Visual Studio solution. If you would like to import some of the functions into your own project, the code is free to be used.

    SerialDataScope

    This application is a ASCII-based data scope.

    This application is a ASCII-based data scope. When used with a 'spy' cable such as the CBL-Full-1A product from www.commfront.com this progrmam shows the ASCII chars on both sides of a comm link. There are three main tabs on the user interface. The 'Vertical' tab displays the comm link conversation in a vertically-scrolling half-duplex mode. Each 'side' of the conversation is detected by the user-configured 'start msg' and 'end msg' byte sequence. The 'Horizontal' tab shows bytes, one at a time, as they are received on each side of the link so the relative timing relationships can be monitored. Printable ASCII chars are shown. Non-printable are shown with a '0x' prefix. The two sides of this link referred to as 'Port 1' and 'Port 2'. Each side must communicate at the same baud rate. Each side can have its' own start message and end message character configurations. A log tab where state and error messages can be reviewed.
