This method always makes the metric writable; however, its timestamp will not be writable, i.e. Sparkplug host application will not be able to modify them. If you need a different behavior, use one of the WriteFunction(SparkplugMetric,Type,Func<SparkplugData,Boolean>) method overloads instead.

This method does not change the readability access of the metric. By default, metrics are readable. If you need a metric that is writable but non-readable, combine this method with calling Readable(SparkplugMetric,Boolean) method with the 'readable' parameter set to false.

The write function returns a boolean that indicates the outcome of the Sparkplug write operation. If the outcome of your write operation should always be successful, you can make your code a bit simpler by using one of WriteValueAction<TValue>(SparkplugMetric,Type,Action<TValue>) method overloads instead.
