AppContextSwitchOverrides 不起作用，在授权上下文中找到 3 个 DNS 声明

Question

我在 azure 上的角色中得到“在授权上下文中找到 3 个 DNS 声明”。我在这里找到了解决方案，但它不起作用。起初我添加了配置设置

<AppContextSwitchOverrides value="Switch.System.IdentityModel.DisableMultipleDNSEntriesInSANCertificate=true" />

它没有帮助。

然后我尝试通过代码设置

    public override bool OnStart()
    {
        AppContext.SetSwitch("Switch.System.IdentityModel.DisableMul??tipleDNSEntriesInSAN??Certificate", true);

        return base.OnStart();
    }

结果是一样的。我已经安装了服务总线版本 2.7.6 和 .net 4.6.2。我无法将服务总线更新到更高版本，因为 signalR 不适用于服务总线版本 >= 3。

Answer 1

我使用服务总线底板创建一个示例，将消息分发到每个角色实例，这在我这边工作得很好。请参考并在您身边测试一下。

在 Startup.cs 类中配置背板

public void Configuration(IAppBuilder app)
{
    string connectionString = "<Service Bus connection string>";
    GlobalHost.DependencyResolver.UseServiceBus(new ServiceBusScaleoutConfiguration(connectionString, "FeHanSignalRChat") { TopicCount = 3 });

    app.MapSignalR();
}

消息可以很好地分发，并且在 Azure 门户上，我可以找到已创建的主题和订阅。
