c# InnerException of socket in XamlParseException -
i have been developing basic c# chat application practice networking in c# , have built stable build application came across strange thing when started second instance of application in visual studio debugger. while first instance running flawlessly second instance gave xamlparseexception in initializecomponents() function. had inner exception of only 1 usage of each socket address (protocol/network address/port) permitted.
what confuses me working , creating , managing of sockets being done in subsequent lines of code on end, how simple parsing of xaml giving rise exception (which parsed flawlessly in case of first instance of application running).
even if program needs have exception thrown due conflicting sockets, should thrown later(while binding tcp/ while sending udp) can debug transmission throwing exception, in case fails @ first line
initializecomponents()only.
thanks lot in advance , please edit title/content more appropriate if needed. if code needed please comment , provide it.
edit- googling gave no possible relation between 2 xamlparseexception , 1 usage of socket exception. xamlparseexception linked errors in xaml apparent while in case of socket exception due conflicting sockets on same port.
here's xaml-code:

of c# main class constructor code:
public mainwindow() { initializecomponent(); get_machine_name(); server_start(); receive_broadcasts(); thread thread = new thread(() => update_available_clients()); thread.name = "bradcast list update"; thread.isbackground = true; thread.start(); . . . . } here exception thrown in line 1 initializecomponents() only, not proceeding subsequent lines actual functions server_start() interact sockets called.

for socket inner exception stacktrace string was:
" @ system.net.sockets.socket.dobind(endpoint endpointsnapshot, socketaddress socketaddress)\r\n @ system.net.sockets.socket.bind(endpoint localep)\r\n @ system.net.sockets.udpclient..ctor(int32 port, addressfamily family)\r\n @ chatapp.mainwindow..ctor() in c:\users\kaustubh\documents\visual studio 2015\projects\chatapplication\chatapp\mainwindow.xaml.cs:line 100"
thanks , if need more code, please tell.
i had data member initialised as
private udpclient broadcast_receiver= new udpclient(15069); and failing bind port , hence error since members being initialised along initilisecomponents() call exception being thrown.
