wpf - Refreshing UI issue when deriving from a UserControl -

i’ve inherited usercontrol add functionality, , works great. myusercontrol in different project, , use in main project, problem anytime open xaml not render until make change , build. after layout refreshes time, if close user control , reopen not display unless build. here xaml

<cc:formusercontrol x:class="module.options.views.accounting.views.journalformview"                    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"                    xmlns:cc="clr-namespace:module.common.controls;assembly=module.common">                                <textbox grid.row="1" text=”some text” /> </cc:formusercontrol> 

here c#

public class formusercontrol : usercontrol, iview {     public formusercontrol()     {         setvalue(viewmodellocator.autowireviewmodelproperty, true);     }      public override void endinit()     {         if (canrefresh)         {             resources.mergeddictionaries.add(             new resourcedictionary().addresource("/resource.dictionaries;component/styles/mycontrolstyle.xaml"));             style = findresource("mysercontrolstyle") style;         }            base.endinit();     }      public bool canrefresh     {         { return (bool)getvalue(canrefreshproperty); }         set { setvalue(canrefreshproperty, value); }     }      public static readonly dependencyproperty canrefreshproperty =         dependencyproperty.register("canrefresh", typeof(bool), typeof(formusercontrol), new propertymetadata(false)); } 

there nothing special code , don’t know why not refresh until buid. these 2 files in different projects, , xaml work anychange add space , build. ideas?

kind regards

after make changes usercontrol in different project, designer figures out usercontrol it's displaying out of date. therefore need build/rebuild solution designer can catch up , display latest changes on designer.

when build or run solution, things should okay.
