c# - MyApp.App does not contain a definition for Initialize after adding ResourceDictionary -

everything fine till add resource dictionary. looks like:

app.xaml:

<application x:class="myapp.app"          xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"          xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"             xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"          xmlns:local="clr-namespace:myapp.myapp.common"> <application.resources>     <resourcedictionary>         <resourcedictionary.mergeddictionaries>          </resourcedictionary.mergeddictionaries>         <local:mainmenubuttonvisibilityconverter x:key="mainmenubuttonvisibilityconverter" />  <!-- withoot line fine-->     </resourcedictionary> </application.resources> 

app.g.cs:

namespace myapp { ...     public static void main() {         myapp.app app = new myapp.app();         app.initializecomponent(); // <------ here problem         app.run();     } } 

mainmenubuttonvisibilityconverter:

namespace myapp.myapp.common { public class mainmenubuttonvisibilityconverter : ivalueconverter { ... }} 

my error:

error   2   'myapp.myapp.app' not contain definition 'initializecomponent' , no extension method 'initializecomponent' accepting first argument of type 'myapp.myapp.app' found (are missing using directive or assembly reference?)    

my project name: myapp folder viewmodels , common caled: myapp

what doing incorrectly while adding resource dictionary?

app.xaml.cs

namespace myapp.myapp { public partial class app : application {     private shell shell;     private myappmain myappmain;      public app()     {     }      private void dispatcher_unhandledexception(object sender, dispatcherunhandledexceptioneventargs e)     {         messagebox.show(e.exception.message, "", messageboxbutton.ok, messageboximage.hand);         e.handled = true;     }      protected override void onstartup(startupeventargs e)     {         base.onstartup(e);         base.dispatcher.unhandledexception += new dispatcherunhandledexceptioneventhandler(this.dispatcher_unhandledexception);         myappmain = new myappmain("");     }  }} 

have tried change order of declarations ? converters should declared @ first in resourcedictionary.

 <resourcedictionary>  <local:mainmenubuttonvisibilityconverter x:key="mainmenubuttonvisibilityconverter" />  <!-- withoot line fine-->         <resourcedictionary.mergeddictionaries>          </resourcedictionary.mergeddictionaries>      </resourcedictionary>
