如何将通知发送到特定的Notification Hub安装模板？

Question

I am registering installations from my .NET backend server code with multiple templates each. For example:

var installation = new Installation
{
    InstallationId = id,
    PushChannel = token,
    Templates = new Dictionary<string, InstallationTemplate>(),
    Tags = new List<string> { "userId:123456" },
    Platform = NotificationPlatform.Gcm
};

installation.Templates.Add("template1", new InstallationTemplate { Body = "{\"data\":{\"message\":\"$(message)\"}}"});
installation.Templates.Add("template2", new InstallationTemplate { Body = "{\"data\":{\"message2\":\"$(message)\"}}"});

await _client.CreateOrUpdateInstallationAsync(installation);

How do I target a specific template when sending a notification? All I see in the SDK is the following:

await _client.SendTemplateNotificationAsync(
    new Dictionary<string, string>
    {
        { "message",  "Hello world." }
    }, "userId:123456");

The SendTemplateNotificationAsync method does not have any parameters that let me specify which template I am targeting (for example, template2 ).

Which template will be used? Am I misunderstanding something here?

InstallationTemplate class has Tags property. That's a way to differentiate between templates.

In your case, it looks like you could just skip tagging the entire installation via Installation.Tags property and use something like userId:123456-template tag on specific templates through InstallationTemplate.Tags . Then invoke SendTemplateNotificationAsync the same way you do, but with the template suffix.
