i found tutorial create facebook application using fb c# sdk @ http://blog.prabir.me/post/facebook-csharp-sdk-writing-your-first-facebook-application-v6.aspx. in tutorial, has used winforms, wanted courageous , made same program wpf.

i face problem see has happened many users, couldn't figure out how can fix code. receive error shown below:

no overload 'connectwithfacebook_click' matches delegate 'system.windows.routedeventhandler'

i don't syntax errors, when start program, error appears (i think that's call runtime error?). double click error, points wpf code.

here's wpf code:

        <button x:name="connectwithfacebook" content="connect facebook" horizontalalignment="left" padding="10, 5"  margin="520,10,0,0" verticalalignment="top" background="#ff3782dc" foreground="white" borderbrush="{x:null}" fontfamily="segoe wp n light" fontsize="14" height="31" width="159" click="connectwithfacebook_click"/>

here's c# code:

private void connectwithfacebook_click(facebookoauthresult facebookoauthresult)     {         var fblogindialog = new facebooklogindialog(appid, extendedpermissions);         fblogindialog.showdialog();          displayappropriatemessage(fblogindialog.facebookoauthresult);          if (facebookoauthresult != null)         {             if (facebookoauthresult.issuccess)             {                 console.writeline("you have connected facebook account!");             }         }     }
