ASP.NET core has many features like:

• Modular design.
• Cross platform.
• Open sourced
• Dependency injection
• Ships entirely as Ne Gut packages

But main feature is cross-platform according to many.

With respect to cross platform:

If developing desktop applications it is an advantage. But how it is useful in web development. Because browser is used to access them.

I think hosting them on any platform servers is the only advantage of cross-platform for web applications.Am I right?
