In Defense of Lazy Loading

I don’t know how this happened but for the last couple years (at least), whenever I read an author who writes about ORMs, I often see a sentiment like this: “ORMs are fine, just make sure you disable this pesky feature called Lazy Loading”.

It’s like this feature is not even needed and only brings confusion and performance issues to everyone who chooses to use it. Well, as you may guess from the title of this article, I disagree with this point of view completely. 

Console Apps are considered unimportant nowadays. I want to show why they are not IMHO and how to approach them after the latest C# updates. 

The consolidated repositories are going to be about .NET 5 and going forward. It will not be possible to build .NET Core 3.1 or earlier from these repositories. 

The previews of EF Core 5.0 require .NET Standard 2.1. This means:

• EF Core 5.0 runs on .NET Core 3.1; it does not require .NET 5.
  • This may change in future previews depending on how the plan for .NET 5 evolves.
• EF Core 5.0 runs on other platforms that support .NET Standard 2.1.
• EF Core 5.0 will not run on .NET Standard 2.0 platforms, including .NET Framework. 

An easy way to perform background job processing in your .NET and .NET Core applications. No Windows Service or separate process required. CPU and I/O intensive, long-running and short-running jobs are supported. Backed by Redis, SQL Server, SQL Azure and MSMQ.

Invoking event handlers in C# has always been a bit of a pain, because an event with no subscribers is usually represented as a null reference.
