This is a defense of the most prolific and dedicated public servant that has graced the world in my lifetime. One man has added hundreds of billions, if not trillions of dollars of value to the global economy. This man has worked tirelessly for the benefit of everyone around him. It is impossible to name a publicly traded company that has not somehow benefited from his contributions, and many have benefited to the tune of billions. In return for the countless billions of wealth that people made from the fruits of his labor, he was rewarded with poverty and ridicule. Now that the world is done taking from him, they are heading to the next step of vilifying him as incompetent.

MongoDB Stores structured data as a JSON-like documents

In this section, I’m going to cover how you can use SignalR outside of a Hub. In most asp.net core applications, you will likely want to communicate with the connect clients from within your application but outside of a Hub. You can accomplish this by using the HubContext.

For example, an ASP.NET Core MVC Controller or any other class that is instantiated by ASP.NET Core’s Dependency Injection.

The HubContext allows you to send messages to your connected clients. It has many of the same features to communicate with clients as when you are inside of a Hub.
