WCF methods sharing a dictionary
- by YeomansLeo
I'm creating a WCF Service Library and I have a question regarding thread-safety consuming a method inside this library, here is the full implementation that I have until now.
namespace WCFConfiguration
{
[ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall, ConcurrencyMode = ConcurrencyMode.Single)]
public class ConfigurationService : IConfigurationService
{
ConcurrentDictionary<Tuple<string,string>, string> configurationDictionary = new ConcurrentDictionary<Tuple<string,string>, string>();
public void Configuration(IEnumerable<Configuration> configurationSet)
{
Tuple<string, string> lookupStrings;
foreach (var config in configurationSet)
{
lookupStrings = new Tuple<string, string>(config.BoxType, config.Size);
configurationDictionary.TryAdd(lookupStrings, config.RowNumber);
}
}
public void ScanReceived(string boxType, string size, string packerId = null)
{
}
}
}
Imagine that I have a 10 values in my configurationDictionary and many people want to query this dictionary consuming ScanReceived method, are those 10 values be shared for each of the clients that request ScanReceived? Do I need to change my ServiceBehavior?
The Configuration method is only consumed by one person by the way.
