In CSharp, If you create the method/function outline with it's Parms, then when you add the three forward slashes it will auto generate the summary and parms section.
So I put in:
public string myMethod(string sImput1, int iInput2)
{
}
I then put the three /// before it and Visual Studio's gave me this:
/// <summary>
///
/// </summary>
/// <param name="sImput1"></param>
/// <param name="iInput2"></param>
/// <returns></returns>
public string myMethod(string sImput1, int iInput2)
{
}
