In .Net is the 'Staticness' of a public static variable limited to an AppDomain or the whole process? -

is 1 copy of public static variable created each appdomain in process or 1 copy whole process? in other words if change value of static variable within 1 appdomain, affect value of same static variable within appdomain in same process?

it per application domain proven example:

public class foo {     public static string bar { get; set; } }  public class test {     public test()     {         console.writeline("second appdomain: {0}", foo.bar);     } }  class program {     static void main()     {         // set value in main appdomain         foo.bar = "bar";         console.writeline("main appdomain: {0}", foo.bar);          // create second domain         var domain = appdomain.createdomain("secondappdomain");          // instantiate test class in second domain         // constructor of test class print value         // of foo.bar inside second domain , null         domain.createinstance(assembly.getexecutingassembly().fullname, "test");     } }
