Provide change notifications in the .Net client about .net-sdk

[jochenz]

I see. Makes perfect sense then :-)

Yes, we will be able to use it!

Hello @jochenz ,

We already have a change notification built into the SDK in case of the auto polling mode:
https://configcat.com/docs/sdk-reference/csharp#auto-polling-default
https://github.com/configcat/.net-sdk/blob/master/src/ConfigCatClient/Configuration/AutoPollConfiguration.cs#L31

It is basically calling the event in case of the underlying config.json changes in any way.
I would use it in a way like this:

var myCurrentValue = ...;
var clientConfiguration = new AutoPollConfiguration
    {
        SdkKey = "#YOUR-SDK-KEY#"
    };

IConfigCatClient client = new ConfigCatClient(clientConfiguration);

clientConfiguration.OnConfigurationChanged += (sender, args) => 
    {
        var newValue = client.GetValue('key', ...));
        if ((newValue != myCurrentValue) 
        {
             myCurrentValue = newValue;
             // do the necessary things.
        }
    };

What do you think?

Cheers,
Lali

Ok, that was a little hidden ;-)

Not in the IConfigCatClient interface, but in the configuration to create the client... Overlooked that one.

Yes, because it can only be used in the Auto polling mode and we didn't want to confuse our customers with this on the IConfigCatClient itself.
I hope you'll be able to use it.
