Using Entity Framework Core to process Azure Service Messages in ASP.NET Core
This article shows how to use Entity Framework Core together with an Azure Service Bus receiver in ASP.NET Core. This message handler is a singleton and so requires that an Entity Framework Core context inside this singleton is not registered as a scoped service but created and disposed for each message event. Code: https://github.com/damienbod/AspNetCoreServiceBus Posts […]
Using Azure Service Bus Topics Subscription Filters in ASP.NET Core
This article shows how to implement Azure Service Bus filters for topic subscriptions used in an ASP.NET Core API application. The application uses the Microsoft.Azure.ServiceBus NuGet package for all the Azure Service Bus client logic. Code: https://github.com/damienbod/AspNetCoreServiceBus Posts in this series: History Azure Service Bus Topic Sender The topic sender from the previous post was […]
Using Azure Service Bus Topics in ASP.NET Core
This article shows how to implement two ASP.NET Core API applications to communicate with each other using Azure Service Bus Topics. This post continues on from the last article, this time using topics and subscriptions to communicate instead of a queue. By using a topic with subscriptions, and message can be sent to n receivers.
