[Mono-list] Keyword this or base expected(CS1018)

[gennady wexler]

of course this wont compile, since you class needs to be deriving from a
class which we will consider a base that has a constructor that takes your
type of arguments:

so to correct the below should look like this:

 class MyBase {
     public MyBase (Glade.XML gxml, Database database) {
         // rest of your construction logic goes here
     }

 class MyClass : MyBase {
     public MyClass (Glade.XML gxml, Database database)
         : base(gxml, database) {
         // rest of your construction logic goes here
     }

hope this helps.
