Is it possible that the IIS Express Server doesn't make my IP address available for remote devices? I've done this once using Java and it worked perfectly fine, I don't understand why it won't work here. public class Program { public static void Main(string args) { BuildWebHost(args).Run(); } public static IWebHost BuildWebHost(string args) => WebHost.CreateDefaultBuilder(args) .UseUrls("http://localhost:8080", "

0 0 $begingroup$ I came across this weird question in a question paper : $B =lbrace1,2,3,4rbrace . text{ A set } Ssubseteq Btimes B text{ is called symmetric set iff, for all x,y } in S \ qquadqquadqquadqquadqquadqquad (x,y) in S Rightarrow (y,x) in S $ . Find the number of symmetric sets of B. At first , I thought the answer is $4.quad[(1,1),(2,2),(3,3),(4,4,)]$ . Now the question begs if an empty set " $emptyset$ " can be included to the list? What is the answer? combinatorics elementary-set-theory share | cite | improve this question edited Feb 2 at 22:23 Maria Mazur
