You can run a single monolithic instance of a server application only if the number of clients accessing your application doesn’t exceed a couple of thousand. But what if you expect hundreds of thousands, or even millions, of clients to connect to your application simultaneously? Then a single instance of Continue Reading

Securing your applications is very important, especially if they are accessible via a network that you don’t have control over, such as public internet. Without security, absolutely anyone can connect to your application, including someone who is up to no good. And this may result in a catastrophic failure that Continue Reading

We have already covered all the fundamental ways of using SignalR messages. We have learned how to set up clients of all supported types, how to send messages to specific clients and how to use data streams, both client-to-server and server-to-client. Now, we will be moving on to more advanced Continue Reading

Until this point, we have only covered the use of singular messages in SignalR. But SignalR also supports message streaming. Streaming is when, instead of sending all data at ones, you send it in chunks. Perhaps, it’s a large object that gets split into smaller parts. Or it could be Continue Reading

SignalR hub can broadcast a message to all connected clients. But this is far from being the only way you can use SignalR. The hub allows you to send messages to individual clients. You can also group clients together and send messages to specific groups of clients. And this is Continue Reading

SignalR Hub is only useful if you have clients connected to it. And in this article, you will learn how to connect in-browser clients. We will start with in-browser clients because they are slightly easier to set up than external clients. For example, you won’t have to create external applications Continue Reading

SignalR is an inbuilt ASP.NET Core library that makes it easy to create interactive real-time applications. It enables fast two-way messaging between the client and the server. Under the hood, it uses some complex logic to enable all of this. But its external APIs hide all this complexity, so using Continue Reading

Many design patterns were developed with SOLID principles in mind. Therefore it will be hard to learn design patterns unless you know SOLID principles. But SOLID principles aren’t merely a tool to help you learn design patterns. Every software developer who uses object-oriented programming languages needs to be familiar with Continue Reading

My book, SignalR on .NET 6 – the complete guide, is out now! Also available in print. A while ago, when ASP.NET Core didn’t even exist, Microsoft has created a library for .NET Framework-based ASP.NET that enabled a two-way communication between the clients and a server in real time. This Continue Reading

This article is a chapter from the book Microservices Communication in .NET Using gRPC Since gRPC is often used for processing large volumes of data inside a distributed application, this communication mechanism must be optimized for the best performance. In this chapter, we will cover some best practices when it Continue Reading

This article is a chapter from the book The easiest way to learn design patterns This chapter summarizes which design patterns can be used to solve any specific type of a software development problem. It’s intended to be a reference guide to help you find the right design pattern quickly. Continue Reading
