When running an endpoint within the context of the Visual Studio debugger, the required queues are created automatically on startup to facilitate development. However, when deploying this endpoint to a server, starting the endpoint from the command prompt will not create the necessary queues. Creation of queues is a one-time cost that should happen during installation.
To retrieve the list of available options for the host, run the following at the command line:
To install the process as a Windows service, include
/ as a command line argument to the host. Using
/ also causes the host to invoke the installers.
NServiceBus.Host.exe /install [/serviceName:<string>] [/displayName:<string>] [/description:<string>] [/endpointConfigurationType:<string>] [/endpointName:<string>] [/scannedAssemblies:<string>] [/dependsOn:<string>] [/sideBySide] [/startManually] [/username:<string>] [/password:<string>] [<profile>]
Here is an example of the
/ command line:
NServiceBus.Host.exe /install /serviceName:"MyPublisher" /displayName:"My Publisher Service" /description:"Service for publishing event messages" /endpointConfigurationType:"QualifiedNameSpace.EndpointConfigType, AssemblyName" /username:"corp\serviceuser" /password:"p@ssw0rd!"
To set the name of the Windows service in the registry, specify
/. By default, the name of the service is the name of the endpoint and the endpoint name is the namespace of the endpoint configuration class.
To set the name of the Windows service as it is displayed in the Windows Service Manager, specify
/ is not specified, then the default ServiceName will be used as the display name and not the provided service name as specified in the
To set the description shown in the Windows Service Manager, specify

Configures the name of the endpoint. By default, the endpoint name is the namespace of the endpoint configuration class.
Configures NServiceBus to scan only the specified assemblies. The
scannedAssemblies parameter must be provided for each assembly to include. E.g.:
NServiceBus.Host.exe /install /scannedAssemblies:"NServiceBus.Core" /scannedAssemblies:"NServiceBus.Host" /scannedAssemblies:"My.Endpoint.Assembly"
The host loads the assemblies by invoking the
Assembly. method. This approach ensures that the specified assembly and its dependent assemblies will also be loaded.
/scannedAssembliesparameter, be sure to include at least
NServiceBus.Hostas well as any other referenced NServiceBus plugins. There is no need to include
NServiceBus.Corein the list since it is referenced by
Specifies the names of services or groups which must start before this service, e.g.
/. Multiple services or groups are separated by a comma.
By using the
/ argument, the endpoint version will be appended to the service name. This setting enables side-by-side operations by allowing multiple endpoints with different versions to run at the same time.
By default, Windows services start automatically when the operating system starts. To change this setting, add

NServiceBus version 7 and above supports Group Managed Service Accounts (GMSA). When specifying a GMSA, the
/ command line switch should include the trailing dollar sign e.g.

If a service name is specified when installing a service, be sure to pass it to the uninstall command:
