• adds member update tags support
• updates existing commands to include the new API version
• intentionally does not expose the new upgrade-history resource

Validation

• generated through the aaz-dev workspace HTTP API
• imported only the six approved existing AppNet resources
• verified no upgrade-history command or model is generated
• git diff --check

The --network-name parameter is defined in the 2026-08-01-preview AppLink member resource model at:

• appnet member join: $resource.properties.connectivityProfile.network
• appnet member update: $properties.properties.connectivityProfile.network

Both map to connectivityProfile.network and use the help text: Name of the network for the Application Network member.

appnet member join exposes --network-name here. It maps to $resource.properties.connectivityProfile.network.

[German Robayo (german1608)]

appnet member update exposes --network-name here. It maps to $properties.properties.connectivityProfile.network.

Focused AAZ model diff for the member resource (2025-08-01-preview -> 2026-08-01-preview):

# appnet member join
+ <argGroup name="ConnectivityProfile">
+   <arg type="string"
+        var="$resource.properties.connectivityProfile.network"
+        options="network-name"
+        group="ConnectivityProfile">
+     <help short="Name of the network for the Application Network member."/>
+   </arg>
+ </argGroup>
+
# Join request-body mapping
+ <prop type="string"
+       name="network"
+       arg="$resource.properties.connectivityProfile.network"/>
+
# appnet member update
- <arg type="object"
-      var="$properties.properties.connectivityProfile.privateConnect"
-      options="private-connect"
-      hide="True"
-      group="Connectivity">
-   ...
- </arg>
+ <argGroup name="ConnectivityProfile">
+   <arg type="string"
+        var="$properties.properties.connectivityProfile.network"
+        options="network-name"
+        group="ConnectivityProfile">
+     <help short="Name of the network for the Application Network member."/>
+   </arg>
+ </argGroup>
+
# Update request-body mapping
- <prop type="object"
-       name="privateConnect"
-       arg="$properties.properties.connectivityProfile.privateConnect">
-   ...
- </prop>
+ <prop type="string"
+       name="network"
+       arg="$properties.properties.connectivityProfile.network"/>

The same update removes the hidden update-time --metadata argument and adds network to the member response schemas.

[German Robayo (german1608)]

Added a server-authored appnet member join example demonstrating --network-name shared-network-1 without --east-west-gateway or --private-connect-subnet. The generated AAZ diff is limited to Commands/appnet/member/_join.md; existing network-name option customizations were preserved.
