Evaluates the value.

public override Task<IDataSource> EvaluateAsync(ActivityContext context, CancellationToken cancellationToken = default)

context ActivityContext: The activity context.
cancellationToken CancellationToken: A token that can request cancelling the evaluation.

Task<IDataSource>: A task that represents the asynchronous operation. The value of its Result property contains the resulting value.

ArgumentNullException: context is null.
Exception: The value could not be evaluated. Possible exceptions depend on the implementation.

Returns a string that represents the current object.
