The lost art of writing SQL queries
I noticed that most (junior) developers no longer are able to write anything but the most trivial SQL queries.  Time to fix that! 

3. Can be used in proprietary works
The license policy allow you to use this piece of code even inside commercial (not open source) 
projects. So you can use this software without giving away your own (precious?) source code.

Today, the Entity Framework Core team announces the first preview release of EF Core 6.0. This release includes new attributes, built-in functions, and database-specific improvements to SQLite and SQL Server capabilities.

Columnstore indexes were first introduced in SQL Server 2012. They are a new way to store the data from a table that improves the performance of certain query types by at least ten times. They are especially helpful with fact tables in data warehouses. 

A .NET guideline specifies that an application should never throw a NullReferenceException. However, many applications and libraries do. The NullReferenceException is the most common exception happening. That’s why C# 8 tries to get rid of it. With C# 8, reference types are not null be default. This is a big change, and a great feature. However, what about all the legacy code? Can old libraries be used with C# 8 applications, and can C# 7 applications make use of C# 8 libraries?

This article demonstrates how C# 8 allows mixing old and new assemblies. 

The project includes the implementation of FullCalendar in JavaScript ES6+ and comes wired with the necessary database access layer (including SQL statements) to interact with SQL Server. 

If you've been a docker user for long time, I think it will take some persuading for you to even consider to switch to different tooling.
