Day 14. Components and .NET
Reusability is what makes writing applications in .NET better than other development environments. This week you've written a lot of code that could be modified slightly and be reused in all of your applications. All the extensible markup language (XML) and ADO.NET code that you wrote has standard functionality that you could share among multiple applications. By writing components, you can write code that can be shared among multiple forms or classes in your applications or across multiple applications. Today, you learn
- What a component is in .NET
- How to determine what types of components to write and when
- How to write reusable code in .NET assemblies
- How to write and implement your own namespaces
- How to use unmanaged COM DLLs in .NET
