Callback function in c# - WPF -

i have class define class b:

b b=new b() 

i call function in class b.when tried make function- static- got error cause have in function-

dispatcher.begininvoke... 

is there way it?

why not pass reference of b.

something like

public class {     public a()     {         b b = new b(this);        } }  public class b {     public b(a a)     {      } } 

or make property of b.

something like

public class {     public a()     {         b b = new b                   {                       mya =                   };     } }  public class b {     public mya; }
