ms dynamics crm. how to share variables between plugins of different types -

i have 2 plugin preentityupdate , postentityassign. inside update postentityupdate execute assign , invokes postentityassign plugin execution. possible pass shared variables preentityupdate postentityassign? tried unsuccessfully...

i think should through parent context of plugin , try find necessary shared data sharedvariables collections. here example of code:

 public new void execute(iserviceprovider serviceprovider)     {         string shareddatakey = "your key defined here";         bool found = false;          ipluginexecutioncontext currentcontext = (ipluginexecutioncontext)serviceprovider.getservice(typeof(ipluginexecutioncontext));          // find shared data among parent contexts         ipluginexecutioncontext context = currentcontext;         while (context != null)         {             if (context.sharedvariables.containskey(shareddatakey))             {                 found = true;                 break;             }              context = context.parentcontext;         }          object shareddata = null;         if (found)         {             // data found in parent context             shareddata = context.sharedvariables[shareddatakey];         }         else         {             // data not found in parent context, thereby create new 1             shareddata = new object();             currentcontext.sharedvariables[shareddatakey] = shareddata;         }          // want 'shareddata'     } 

something similar used situation described. namely, have 1 pre update entity plugin sometime update related entity leads calling instance of plugin.
