In MonoDevelop, when I type "///", it auto-generates an xml-style comment like this:
/// <summary>
/// Describes the variable x
/// </summary>
int x = 0;
Is there a way to get this behavior in Visual Studio Code?
This feature is not available out-of-the-box with VS Code, but like most features is available via third-party extensions. As of the time of this answer, here is a popular extension that provides some XML comments support to VS Code:
C# XML Documentation Comments Support for Visual Studio Code
If that extension doesn't work for you, you may be able to find alternatives by searching the VS Code Marketplace
