vb.net - ASP.net postbackurl to same page outside VS project vs. within -

i have been able post same page within script successfully... however, when created web application project in visual studio 2013 express web , run same script, postback doesn't work... page refreshes... also, instead of before url "webform1.aspx" shows "webform" this:

http://localhost:49201/webform1

within project, form tag looks this:

<form method="post" action="webform1" id="form1">

vs outside looks this:

http://localhost:49621/webform1.aspx

and form tag looks this:

<form method="post" action="webform1.aspx" id="form1">

is there weird file extensions need configure postback same page?

edit:

when run programme outside of vs project, posts perfectly.

when add together programme web application project within vs, post doesn't work, page refreshes...

code below:

<asp:button id="button1" runat="server" commandname="submit" postbackurl="~/webform1.aspx" text="button" />

after 7 hours of searching... here's did prepare issue:

create brand new project in vs select framework 4 (versus 4.5 or 4.5.1) add together new item project menu (web form) paste code, update web.config

the script posts, makes no sense, works. hope helps not waste day of life.
