Microsoft has open sourced a .NET 5 C# Language Extension for SQL Server, allowing developers to work with relational data in the company's flagship programming language.
In announcing the sixth preview release of EF Core 6.0, Microsoft noted the dev team for the open source, cross-platform data development framework is still playing catch-up with EF6, the traditional object-relational mapping (ORM) framework formerly tied to the Windows-only .NET Framework.
Some six years in the making, an effort to quicken app startup times in Entity Framework Core via compiled models has been realized in the new v6.0 Preview 5.
SQL Server's OpenJson function will let you dismantle JSON structures into relational tables, including tables with foreign/primary key relationships.
Here's how you can use SQL Server's OpenJson function to dismantle JSON structures into relational tables targeting either transactional systems or data warehouses.
The new Entity Framework Core 6.0 Preview 4 is described as a "performance edition," with the dev team turning from years-long concerns -- such as catching up to the old Entity Framework and adding new features -- to focus on speed.
Dr. James McCaffrey of Microsoft Research provides a code-driven tutorial on PUL problems, which often occur with security or medical data in cases like training a machine learning model to predict if a hospital patient has a disease or not.
