I’ve found that Kestrel is an excellent choice for .NET Core applications, especially when targeting cross-platform deployments or requiring high-performance web servers. However, it’s essential to properly configure Kestrel, such as setting up HTTPS and other security features, to ensure a secure and reliable web application.
In this situation, we can use Task.WaitAll to effectively wait until A and B are finished, and then launch method C. Of course, this can add complexity to our code, so it is a tool that should only be used to solve specific problems. Records are a better choice when defining Database Rows, Value Objects, or Data Transfer Objects; pure value objects that don’t contain logic at all or contain very small chunks of logic .
