Best way to check for null parameters (Guard Clauses)

For example, you usually don\'t want parameters in a constructor to be null, so it\'s very normal to see some thing like

if (someArg == null)
{
    throw new Arg

There is a nuget package called SwissKnife. Install SwissKnife from nuget gallery. It provides you with many options starting with null checking for arguments Argument.IsNotNullOrEmpty(args,"args") under SwissKnife.Diagnostics.Contracts namespace alongwith with option idoim and many more. You can set Option _someVar and then check if _someVar.IsSome or _someVar.IsNone. This helps against nullable classes as well. Hope this helps.
