I have been having trouble with inProc session variables returning null. The most current is trying to set a Session Variable in the PageLoad of Default. Here is my code.

   string NameNew = Page.User.Identity.Name;
    if (NameNew.Contains('\\'))
    {
        NameNew = NameNew.Split('\\').Last();
    }
    if (Session != null)
    {
        Session["UsersName"] = NameNew;
    }

When debugging it returns System.NullReferenceException: 'Object reference not set to an instance of an object.'

I have tried updating vs, checking IIS express for session issues, moved other session objects to base class. I am at a loss.

Are you sure this is related to session? Which line exactly is it throwing on, because any of Page.User.Identity.Name could be null and cause this error – Porco Mar 19 '21 at 18:42
Session["UsersName"] = NameNew; is throwing the exception. – Doug Farrell Mar 19 '21 at 18:43
Is `Session` null at that point? – Flydog57 Mar 19 '21 at 18:46
Flydog57 No it's not. – Doug Farrell Mar 19 '21 at 18:48
It's answered here I bet: https://stackoverflow.com/questions/5774248/system-nullreferenceexception-when-checking-if-null?rq=1 – Porco Mar 19 '21 at 18:49
Porco encapsulated in both if (Context != null) and if (Context.Session != null) same result. – Doug Farrell Mar 19 '21 at 18:56
@Doug Farrell, can you provide the initial string about NameNew? Also, have you defined the session before it? If so, please provide the related code about session. – Jack J Jun Mar 22 '21 at 06:37
