In C#, you can write XML documentation comments using a special format to generate XML documents. The XML documentation comments start with three slashes “///” followed by a descriptive comment content. For example:

/// <summary>
/// This method adds two numbers together and returns the result.
/// </summary>
/// <param name="num1">The first number to be added</param>
/// <param name="num2">The second number to be added</param>
/// <returns>The sum of the two numbers</returns>
public int AddNumbers(int num1, int num2)
{
    return num1 + num2;
}

In the example above, the

tag is used to provide a brief description of the method, the tag is used to describe the method’s parameters, and the tag is used to describe the method’s return value. These comments will be extracted by the compiler and generated into an XML document file, so that other developers can view this information through an IDE or documentation tool.

To generate an XML document file, you can enable the “XML Documentation File” option in the “Build” tab of project properties, then compile the project. The generated XML document file will be saved in the output directory along with the compiled assembly.
