The framework is particularly useful for developers building scalable backend systems, microservices, and high-performance web services. It's commonly adopted by professional software engineers and development teams.

help ASP.NET Core FAQ

Can I run ASP.NET Core applications on Linux servers?

Yes, ASP.NET Core is a cross-platform framework, meaning you can host your applications on Linux, macOS, and Windows. This is a major shift from the older, Windows-only legacy ASP.NET framework.

What is the difference between .NET Core and ASP.NET Core?

.NET Core is the underlying runtime and base class libraries used for all types of applications, while ASP.NET Core is the web framework built on top of it. You need the .NET runtime installed to run an ASP.NET Core app.

Is ASP.NET Core completely free to use for commercial projects?

Yes, ASP.NET Core is entirely free and open-source under the MIT license. You can build and deploy commercial web applications and APIs without paying licensing fees to Microsoft.

How does ASP.NET Core handle real-time communication like WebSockets?

It uses a built-in library called SignalR, which simplifies the process of adding real-time web functionality. SignalR automatically falls back to older techniques if WebSockets are not supported by the client.
