Without using this feature from SQL Server, with EF Core often the behavior when saving objects was overridden to keep the data in the database. With updates from EF Core 6 and using SQL Server (including SQL Azure), just a few lines of code are required to enable temporal tables and use this feature as shown with this article.

Project Tye – easier development with .NET for Kubernetes

Visual Studio 2019 has great support for Docker and Kubernetes. After opening a solution, Dockerfile files and Helm charts can be added from within the Solution Explorer. For simple project, it still can be too complex to work with Helm chats, define deployments and services. Defining a Dockerfile can be avoided as well. With .NET projects, all the information needed to create a docker image can be found in the project file. This is where the Project Tye comes into play – deploy Microservices to Kubernetes with minimal configuration. In this article I’m showing an example creating a .NET Core web application and API service, let it run locally with tye, and deploy it to an Kubernetes cluster.
