#Messaging Samples Main.cs
All Messaging samples include a shared C# file, Main.cs that resides in the
"common" repository folder. It implements a class AppEntryPoint with
a static Main method that the CLR picks up as the main entry point for
the app.
The reason for having a shared entry point to simplify and unify the handling of the required configuration information for Service Bus that is created by the setup script and held in the user profile directory.
The implementation assumes that the sample implements a class Program
with an instance method Run() and will call that method after handling
the configuration data. The specific, invoked Run() method will differ
by the kind of sample and is therefore defined by an interface that Program
is expected to implement.
The entry point can also be used for Windows Forms apps and other apps requiring the
[STAThread] declaration by defining the "STA" symbol in the project settings.
The code first reads the settings from the "azure-msg-config.properties" file that it expects in the root of the user's profile folder. The expected format for the text file are lines holding {property}={value}, separated by line-breaks.
The settings can also be set (or overridden) with environment variables set before the program is invoked:
| Property | Description |
|---|---|
| SERVICEBUS_NAMESPACE | Service Bus namespace name, without domain suffix |
| SERVICEBUS_ENTITY_PATH | Name of the configured entity to use for this sample |
| SERVICEBUS_FQDN_SUFFIX | Service Bus host name suffix, typically "servicebus.windows.net" |
| SERVICEBUS_SEND_KEY | SAS key value of the "samplesend" and "rootsamplesend" SAS rules |
| SERVICEBUS_LISTEN_KEY | SAS key value of the "samplelisten" and "rootsamplelisten" SAS rules |
| SERVICEBUS_MANAGE_KEY | SAS key value of the "samplemanage" and "rootsamplemanage" SAS rules |
