If you need to have objects look alike but don't have any code to share, you don't need inheritance -- you need an interface. Here's an example of how interfaces provide a more flexible way to deal with similar-but-different classes.
You want to use a DLL in multiple projects (it's even possible that other developers at your company might find your DLL helpful). The easiest way to distribute and deploy that DLL, or any other combination of files, is with NuGet. Really.
You can dramatically simplify your code by using classes to define read-only/immutable objects … but to create classes that behave correctly requires a little bit of redirection.
You can dramatically simplify your code by using value objects, but to create a value object that makes sense to the developer who uses it, you need to redefine what the equals sign means. Along the way, Peter points out some problems when you don't use classes to define your data.
Create precise logic dictating which messages an actor will handle and how they will react to them.

Stop trying to make everything work all at once. Instead, use Domain Events to make applications simpler, more scalable and easier to maintain -- and to defer updates until you can't avoid making them.
Implementing Domain Events can dramatically simplify your application while also making it more scalable. Here are some of the implementation options available to you in the .NET environment.
Peter addresses reader's concerns by showing how to implement a read-only/immutable value object.
Readers suggest ways to build a powerful HtmlHelper that simplifies creating typical application Views. Along the way, Peter uses a workaround for extending an anonymous object with additional properties and shows how to extract values from a lambda expression in a View.
If you're not careful, you'll replace your huge, lumbering unmaintainable enterprise applications with a web of applications that can't be changed without blowing each other up. But if you apply the same tools you use inside your applications to your application architecture, you can avoid that.
Ease the pain of concurrent programming with the Actor Model and Akka.NET.

Rather than arbitrarily deciding what code goes into an application and what goes into your business objects, you can lean on the rules that experienced developers have learned to follow to make those crucial decisions.
If you've been creating Data Transfer Objects that integrate several objects into one, then you've created what domain-driven design (DDD) calls an aggregate. But there are some rules you need to follow if you want to reap the benefits that DDD promises toward performance, maintainability and scalability.
Augment your testing framework with Shouldly for improved test code readability and better test failure messages.
