Why use .NET or COM?
The question is about .NET
Answer:
In developing modern and scalable applications for web, desktop, and mobile platforms, especially with C# and Microsoft environments, the .NET framework is usually utilized. On the other hand, COM is based on the Component Object Model, enabling the interoperability of various components of software, especially for legacy systems or integration with older applications of Windows. You can use .NET for new development and COM for legacy integration.
