Methods

Case<R>(Regex, ContextualSelector<String,R>)	Constructs a case based on a regular expression.
Case<T,R>(Func<T,Boolean>, ContextualSelector<T,R>)	Constructs a case.
Catch<T,E>(IDialog<T>, Func<IDialog<T>,E,IDialog<T>>)	When the antecedent IDialog<TResult> has completed, catch and handle any exceptions of type E.
Catch<T>(IDialog<T>, Func<IDialog<T>,Exception,IDialog<T>>)	When the antecedent IDialog<TResult> has completed, catch and handle any exceptions.
ContinueWith<T,R>(IDialog<T>, Chain.Continuation<T,R>)	When the antecedent IDialog<TResult> has completed, execute the continuation to produce the next IDialog<TResult>.
Default<T,R>(ContextualSelector<T,R>)	Constructs a case to use as the default.
DefaultIfException<T,E>(IDialog<T>)	When the antecedent IDialog<TResult> has completed, stop the propagation of an exception of E.
DefaultIfException<T>(IDialog<T>)	When the antecedent IDialog<TResult> has completed, stop the propagation of Exception.
Do<T>(IDialog<T>, Func<IBotContext,IAwaitable<T>,Task>)	Execute a side-effect after a IDialog<TResult> completes.
Fold<T>(IDialog<IEnumerable<IDialog<T>>>, Func<T,T,T>)	Fold items from an enumeration of dialogs.
From<T>(Func<IDialog<T>>)	Construct a IDialog<TResult> that will make a new copy of another IDialog<TResult> when started.
Loop<T>(IDialog<T>)	Loop the IDialog<TResult> forever.
PostEvent<T,E>(IDialog<T>, E)	When the antecedent IDialog<TResult> has completed, post the item to the event queue.
PostToChain()	Post the message from the user to Chain.
PostToUser<T>(IDialog<T>)	Post to the user the result of a IDialog<TResult>.
Return<T>(T)	Creates a IDialog<TResult> that returns a value.
Select<T,R>(IDialog<T>, Func<T,R>)	When the antecedent IDialog<TResult> has completed, project the result into a new IDialog<TResult>.
SelectMany<T,C,R>(IDialog<T>, Func<T,IDialog<C>>, Func<T,C,R>)	When the antecedent IDialog<TResult> has completed, execute the next IDialog<TResult>, and use the projection to combine the results.
Switch<T,R>(IDialog<T>, ICase<T,R>[])	When the antecedent IDialog<TResult> has completed, go through each ICase<T,R> and run the ContextualSelector<T,R>" of the first ICase<T,R> that the returned value by the antecedent dialog satisfies.
Then<T,R>(IDialog<T>, Func<IBotContext,IAwaitable<T>,Task<R>>)	Execute an action after the IDialog<TResult> completes.
Unwrap<T>(IDialog<IDialog<T>>)	When the antecedent IDialog<TResult> where T is IDialog<TResult> completes, unwrap the result into a new IDialog<TResult>.
Void<T,R>(IDialog<T>)	Call the voided IDialog<TResult>, ignore the result, then restart the original dialog wait.
Void<T>(IDialog<T>, IDialogStack)	Call the voided IDialog<TResult>, ignore the result, then restart the original dialog wait.
WaitToBot<T>(IDialog<T>)	Post to the chain the message to the bot after the antecedent completes.
Where<T>(IDialog<T>, Func<T,Boolean>)	When the antecedent IDialog<TResult> has completed, evaluate the predicate and decide whether to continue.
While<T>(IDialog<T>, Func<T,IDialog<Boolean>>, Func<T,IDialog<T>>)	Create a IDialog<TResult> that represents a while loop.
WithScorable<T,Item,Score>(IDialog<T>, IScorable<Item,Score>)	Decorate a dialog with a scorable, so that a scorable can participate on the dialog stack.
