|Microsoft.Azure.ServiceBus|[](https://www.nuget.org/packages/Microsoft.Azure.ServiceBus/)|
This is the next generation Service Bus .NET client library that focuses on queues & topics. If you are looking for Event Hubs and Relay clients, follow the below links:
Azure Service Bus is an asynchronous messaging cloud platform that enables you to send messages between decoupled systems. Microsoft offers this feature as a service, which means that you do not need to host any of your own hardware in order to use it.
This library is built using .NET Standard 1.3. For more information on what platforms are supported see [.NET Platforms Support](https://docs.microsoft.com/en-us/dotnet/articles/standard/library#net-platforms-support).
1. Add an Environment Variable named `azure-service-bus-dotnet/connectionstring` and set the value as the connection string of the newly created namespace. **Please note that if you are using Visual Studio, you must restart Visual Studio in order to use new Environment Variables.**
### Can I manage Service Bus entities with this library?
The standard way to manage Azure resources is by using [Azure Resource Manager](https://docs.microsoft.com/en-us/azure/azure-resource-manager/resource-group-overview). In order to use functionality that previously existed in the .NET Framework Service Bus client library, you will need to use the `Microsoft.Azure.Management.ServiceBus` library. This will enable use cases that dynamically create/read/update/delete resources. The following links will provide more information on the new library and how to use it.
