If you change the value, the old value will be used by the other assemblies until they are re-compiled. static readonly fields static property without set Share WebMar 25, 2010 · const fields can only hold value types or System.String. They must be immutable and resolvable at compile-time. static readonly fields can and generally do hold reference types, which (other than strings) can only be created at runtime. These can (but shouldn't) be mutable types; the only thing that cannot change is the reference itself. egg of creation lost ark quest
