c# - Service Only Works While Debugging -


i have created wcf service , having trouble testing once has been deployed. here powershell using test it: 

$service = new-webserviceproxy -uri http://localhost:16651/service.svc $service.getlist()

when debugging service visual studio f5, can call script without issue. getlist() returns long list of telephone numbers.

however, when host site on iis , run above script, empty return value.

service factory

so following this question, added attribute service.svc: 

factory="system.servicemodel.activation.webscriptservicehostfactory"

however, resulted in script returning error on first line:

new-webserviceproxy : object reference not set instance of object.

which not make sense me, not referencing empty objects... (this error appears when debugging , when hosting on iis).

web.config

next, tried updated web.config per linked question: 

<services>   <service name="lyncwebservice.service">     <endpoint binding="webhttpbinding" contract="lyncwebservice.iservice" behaviorconfiguration="web"/>   </service> </services>  <behaviors>        <servicebehaviors>     </servicebehaviors>     <endpointbehaviors>       <behavior name="web">         <webhttp/>       </behavior>     </endpointbehaviors> </behaviors>

however, when try run powershell script error both during debugging , when hosting on iis (again on first line):

the html document not contain web service discovery information.

i totally lost here , have no idea going wrong. suspect config file, did seem work when debugging vs before messed configuration.

any or guidance appreciated - , please let me know if can provide other information or test anything.

here code makes service currently:

service.svc.cs

namespace lyncwebservice {     [servicecontract]     public interface iservice     {         [operationcontract]         [webinvoke]         list<string> getlist();     }     public class service : iservice     {         public list<string> getlist()         {             return ps.getassignednumbers(@"                 set-executionpolicy remotesigned                 import-module lync                 $(get-csuser).lineuri"             );         }     } }

web.config

<?xml version="1.0"?> <configuration>   <appsettings/>   <system.web>     <compilation debug="true" targetframework="4.0"/>     <httpruntime/>   </system.web>   <system.servicemodel>      <services>         <service name="lyncwebservice.service">         <endpoint binding="webhttpbinding" contract="lyncwebservice.iservice" behaviorconfiguration="web"/>         </service>     </services>      <behaviors>            <servicebehaviors>         </servicebehaviors>          <endpointbehaviors>           <behavior name="web">             <webhttp/>           </behavior>         </endpointbehaviors>     </behaviors>      <protocolmapping>       <!--<add binding="basichttpsbinding" scheme="https"/>-->       <add binding="webhttpsbinding" scheme="https"/>     </protocolmapping>     <servicehostingenvironment aspnetcompatibilityenabled="false" multiplesitebindingsenabled="true"/>   </system.servicemodel>   <system.webserver>     <modules runallmanagedmodulesforallrequests="true"/>     <!--         browse web app root directory during debugging, set value below true.         set false before deployment avoid disclosing web app folder information.       -->     <directorybrowse enabled="true"/>   </system.webserver> </configuration>

thanks jonathan coffey, realised service being run localsystem account.

after changing own user account , hosting original web.config on iis, able retrieve full list using powershell script.

  1. open iis
  2. application pools
  3. right-click application pool
  4. advanced settings...
  5. process model -> identity
  6. custom account (don't forget include domain user name!)

unity3d - Rotate an object to face an opposite direction -

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this

angular - Is it possible to get native element for formControl? -

i've got angular2 reactive form . created formcontrol s , assigned input fields by [formcontrol]=... . understand creates nativeelement <-> formcontrol link. my question: possible nativeelement formcontrol ? wanna myformcontrol.nativeelement.focus() i can share 1 terrible solution works me. in reactive forms can use either 1) formcontroldirective ts mycontrol = new formcontrol('') template <input type="text" [formcontrol]="mycontrol"> or 2) formcontrolname ts myform: formgroup; constructor(private fb: formbuilder) {} ngoninit() { this.myform = this.fb.group({ foo: '' }); } template <form [formgroup]="myform"> <input type="text" formcontrolname="foo"> </form> so these directives write patch like 1) formcontroldirective const originformcontrolngonchanges = formcontroldirective.prototype.ngonchanges; formcontroldirective.proto
