Every adventure begins with a quest, perhaps a desire to build a game, develop a website, or automate a tedious task.
Along the way, you'll encounter obstacles that test your problem-solving skills and push you to expand your knowledge.

How do you create background jobs in .NET?
With Quartz it's just one interface implementation.
- Define a job class
- Register it with Quartz
- Quartz takes care of scheduling and ex*****on
It fully supports DI, so you can inject any services you need.
Jobs have a scoped lifetime, meaning you can inject a DbContext safely.
Once you start using Quartz, it’s hard to go back to other options (not that there aren't any).
I wrote an advanced guide for working with Quartz in .NET.

Can you find what's wrong with this code snippet?
Example 2 is 43x faster at inserting 10,000 records into a database.
What causes such a huge performance difference?
The code between the two examples looks similar.
But if you understand how EF works under the hood, the answer should be obvious.
Every call to SaveChanges means a round-trip to the database.
In the first example, inserting each record means one call to the database.

When I need real-time functionality in my application, there's just one trusted solution:
→ SignalR
SignalR lets you add real-time functionality to your .NET apps.
And it works with any client application like React or Angular or plain JavaScript.
You create a SignalR Hub class. It's a central component in your application that manages client connections and messaging. Clients connect to the Hub to receive and send messages. This means the communication can be two-way.
SignalR abstracts away the transport mechanism from you. Usually this will be WebSockets, but it can fall back to Server-Sent Events or polling.
