How to make XMLFile.xml open instead of Default.aspx by default?

Question

ASP.NET

The site project, the Default.aspx page was created in it, which opens in the browser at 127.0.0.1:8080/opt. The goal is to also open XMLFile.xml from this directory (127.0.0.1:8080/opt/XMLFile.xml). In other words, it is required that xml opens not at 127.0.0.1:8080/opt/XMLFile.xml, but at
127.0.0.1:8080/opt/ Thanks in advance for your replies/
