c# - WiX Votive Managed Custom Action cannot be referenced by other managed code in the same solution? -

question:

is possible reference public static methods held within customaction class, votive generates creating c# managed custom actions, other libraries within same solution?

i'm having trouble getting reference class , method inside c# library c# custom action when trying create test bed ca.

namespace testinstaller.installca {     public class customactions     {          [customaction]          public static actionresult installuistart(session session)          {              //stuff              return begin(<constructed dataclass>);                          }           public static actionresult begin(dataclass dc)          {              //stuff want test          }     } } 

...

namespace testinstaller.installertest {     static class program     {         static void main()         {             //stuff             //this line not valid.             testinstaller.installca.customactions.begin(<constructed dataclass>);         }     } } 

despite me adding reference installca cannot add using statement testinstaller.installca or installca, , compile time error suggests adding reference, have done.

is votive protecting dlls somehow?
