Irresponsible ownership of data is the cause of many leaked emails, data, and other damaging information. Securing a user’s personal information is the job of software developers. If you, as a developer, can decrypt the information stored in the database of the system you are working on, then so can anyone else. In Cryptography in .NET Succinctly, Dirk Strauss will take readers through generating cryptographic signatures, hashing and salting passwords, and when and how to use symmetric vs. asymmetric encryption. 

I was pleasantly surprised by how easy it was to setup and install ASP.NET Core 2.1 on Linux. I did it for the first time in 15 minutes with no previous experience with .NET Core on Linux. I did it the second time, in production, in 5 minutes by following these instructions.

In this article, I show you how to install the .NET Core runtime on CentOS, how to get a sample ASP.NET Core project running on Kestrel as a service for reliability, and how to configure both the code and the firewall to enable remote access. Finally, I discuss what I would do differently for actual production usage.

Updates to .NET Framework 4.8 on Windows 8.1, Server 2012 R2, Server 2012, Windows 7 SP1, and Server 2008 R2 SP1 will continue to be delivered outside of the Windows cumulative update through the existing .NET Framework updates.

.NET Microservices – Full Course, Les Jackson
In this step-by-step tutorial I take you through an introduction on building microservices using .NET. As the name suggests we build everything completely from start to finish –with the full scope of the course outlined in the time-stamp section below. However, at a high-level we’ll cover:

• Building two .NET Microservices using the REST API pattern
• Working with dedicated persistence layers for both services
• Deploying our services to Kubernetes cluster
• Employing the API Gateway pattern to route to our services
• Building Synchronous messaging between services (HTTP & gRPC)
• Building Asynchronous messaging between services using an Event Bus (RabbitMQ)
