com - CreateObject C# -

i have native code com object, , trying instantiate c#. com registered in dcom components , in registry.

this i'v try do:

public static void main(string[] args) {     type t = type.gettypefromprogid("caseconsole.application");      dynamic app = activator.createinstance(t);     dynamic c = app.case;      c.opencase("17-16", 0); } 

if try instantiate com-type then, the:

notimplementedexception 

the execption thrown @ line:

dynamic c = app.case; 

as set breakpoint @ line, i'v looked "app" , error present

i'v looked in type t , shows: iscomobject = true

as vbs works great:

dim app dim c  set app = createobject ("caseconsole.application") set c = app.case  c.opencase "17-16", 0 

as vb.net works

sub main()     dim app     dim c      app = createobject("caseconsole.application")     c = app.case      c.opencase("17-16", 0) end sub 

but not in c#

for c# example looked @ sources

equivalent code of createobject in c#

my guess must invoke methods invokemember or security thing...

please can c# example working?

update rename case c wasn't fault.

your c# program subtly different vbs , vb.net programs. apartment state of thread runs code different. exception comes proxy, should interpreted "running code worker thread not supported". nicely done. fix:

[stathread] public static void main(string[] args) {    // etc.. } 

note added [stathread] attribute. technically not correct this, console mode app not provide correct kind of runtime environment single-threaded com objects if vb.net app works have little fear. if ever notice deadlock you'll know for. worked when used late-binding through invokemember because uses idispatch , has different proxy.
