The necessary step you must take before adding session hosts to an Azure Virtual Desktop host pool is to create a registration key for the host pool. The registration key is a security measure that ensures only authorized session hosts can join the host pool.

The registration key is created in the Azure portal under the host pool's properties. Once the key is generated, it must be shared with the session host machines during the setup process.

To create the registration key for the host pool, follow these steps:

1. Log in to the Azure portal and navigate to the host pool.
2. Select the "Properties" option in the left-hand menu.
3. Under the "Registration" section, select "Generate New Key".
4. A new registration key will be generated. Copy this key to the clipboard.

After the registration key is created, it must be used during the setup process for each session host machine that will be added to the host pool. This ensures that only authorized machines can join the pool and access the virtual desktop environment.

In summary, creating a registration key for the host pool is the necessary step you must take before adding session hosts to an Azure Virtual Desktop host pool.
