dll - C# class library changes not being shown when referenced in another project -

i have class library has few methods , works fine when reference in project.

now wanted add overload 1 of methods, when made change , re-referenced in other project, not show overloaded method , gives standard " method has 1 param invoked 2".

i have tried add optional parameter method instead of overload , same problem occurs.

if change logic in method, these changes there when re-reference library.

does have insight on why may happening??

sample code

public class optumhealth {     public createjobmodelresponse createoptumhealthjob(optumhealthhelper helper)     {         return createoptumhealthjob(helper, false);     }      public createjobmodelresponse createoptumhealthjob(optumhealthhelper helper, bool isupdate)     {         var response = new createjobmodelresponse();          //stuff          return response;     } } 

i can call first method, , calls second method correctly. cannot call second method directly though.

ctrl+shift+b rebuild projects in solution. works me.

you can use configuration manager. check "build" library , rebuild automatically each time compile.
