Please tell me how to create a definstance  for a form  in C# (I have the code  in VB.NET)
 I tried the following code but it gives build error - 'Not all paths return a value'
-------------------------------------------------------------------------------------------------------------------------------------------
                              private static  frm_CSGeoCommand m_CSFormDefInstance  ;
            private static Boolean m_InitializingDefInstance  ;
            public  frm_CSGeoCommand  DefInstance
            {
                  get
                  {
                        if (m_CSFormDefInstance == null |  m_CSFormDefInstance.IsDisposed )
                        {
                              m_InitializingDefInstance = true;
                              m_CSFormDefInstance = new frm_CSGeoCommand();
                               m_InitializingDefInstance = false;      
                              
                        }
                        DefInstance  = m_CSFormDefInstance;
                  }
                  set
                  {
                        m_CSFormDefInstance = value;
                  }
                  
                        
            }

---------------------------------------------------------------------------------------------------------------------------------------------

**************************************************************************************
   Also what is the C# equivalent of the VB.NET code -  System.Reflection.Assembly.GetExecutingAssembly.EntryPoint.DeclaringType
**************************************************************************************

    if you want to see the complete  form sourcecode, it  is available at http://www.geocities.com/samsonks/frm_CSGeoCommand.txt
 
             Thanks
