When you try to install the Azure App Configuration extension to target a specific version, you receive an error message that states that the Azure App Configuration version doesn't exist:

Solution 2: Install again for a supported Azure App Configuration extension version

Try again to install the extension. Make sure that you use a supported version of the Azure App Configuration extension.

Scenario 3: The targeted Azure App Configuration extension version exists but not in the specified region

Because some versions of Azure App Configuration extension aren't available in all regions, you might receive the following error message:

Code: ExtensionTypeRegistrationGetFailed

Message: Extension type microsoft.appconfiguration is not registered in region <region-name>

Solution 3: Install in a different region
