C# System.MissingMethodException

[Flolox]

i just started scripting with c# and at the moment i am trying to create bank accounts.

in Visualstudio there are no errors, but when server starts and loads resource, it cant and uts out this:
 

System.MissingMethodException: No parameterless constructor defined for this object.
   at System.RuntimeTypeHandle.CreateInstance(RuntimeType type, Boolean publicOnly, Boolean wrapExceptions, Boolean& canBeCached, RuntimeMethodHandleInternal& ctor)
   at System.RuntimeType.CreateInstanceSlow(Boolean publicOnly, Boolean wrapExceptions, Boolean skipCheckThis, Boolean fillCache)
   at System.Activator.CreateInstance(Type type, Boolean nonPublic, Boolean wrapExceptions)
   at GTANetworkInternals.GameServer.InstantiateScripts(Assembly targetAssembly, String resourceName)+MoveNext()

   at System.Collections.Generic.List`1.InsertRange(Int32 index, IEnumerable`1 collection)
   at GTANetworkInternals.GameServer.StartResource(String resourceName, String parent)

im really new to this and dont find anything about it.

You need to make a parameterless constructor which calls 'this' of the parameter constructor.
