Issue when trying to use [AzureSqlSyncGroupSchemaModel]::new()

he error you're encountering, "Unable to find type [AzureSqlSyncGroupSchemaModel]," indicates that PowerShell cannot locate the AzureSqlSyncGroupSchemaModel type. This issue often arises when the necessary module isn't imported or isn't available in the current session.

Possible Causes and Solutions:

Module Not Imported:

• Cause: The AzureSqlSyncGroupSchemaModel class is part of the Azure PowerShell modules, specifically within the Az.Sql module.
  • Solution: Ensure that the Az.Sql module is installed and imported into your PowerShell session.

    - **Install the Module:**
    
    ```powershell
    powershell
    Copy code
    Install-Module -Name Az.Sql -AllowClobber -Force
    ```
    
          - **Import the Module:**
    
          ```yaml
          powershell
          Copy code
          Import-Module -Name Az.Sql
          ```
    
                - **Verify Installation:**
    
                ```powershell
                powershell
                Copy code
                Get-Module -Name Az.Sql -ListAvailable
                ```
    
                This command should display the installed version of the `Az.Sql` module.
    
                **Namespace Not Defined:**
    
                   - **Cause:** The `AzureSqlSyncGroupSchemaModel` class resides within a specific namespace that might not be automatically recognized.
    
                      - **Solution:** Explicitly define the namespace in your script.
    
                      ```yaml
                      powershell
                      Copy code
                      using namespace Microsoft.Azure.Commands.Sql.DataSync.Model
                      ```
    
                      This directive ensures that PowerShell recognizes the `AzureSqlSyncGroupSchemaModel` type.
    
                      **Module Not Available in Cloud Shell:**
    
                         - **Cause:** Azure Cloud Shell may not have the latest Azure PowerShell modules pre-installed.
    
                            - **Solution:** Install or update the `Az` modules within your Cloud Shell session.
    
                                  - **Update All Az Modules:**
    
                                  ```yaml
                                  powershell
                                  Copy code
                                  Update-Module -Name Az -Force
                                  ```
    
                                        - **Install Specific Module:**
    
                                        ```powershell
                                        powershell
                                        Copy code
                                        Install-Module -Name Az.Sql -AllowClobber -Force
                                        ```
    
                                              - **Import the Module:**
    
                                              ```yaml
                                              powershell
                                              Copy code
                                              Import-Module -Name Az.Sql
                                              ```
    

Additional Recommendations:

Use the Latest Az Module: Ensure you're using the latest version of the Az PowerShell module, as it includes the most recent cmdlets and features.

• Install the Latest Az Module:

   powershell
   Copy code
   Install-Module -Name Az -AllowClobber -Force

  - **Import the Az Module:**
  
  ```haskell
  powershell
  Copy code
  Import-Module -Name Az
  ```
  
  **Verify Module Installation:** After installation, confirm that the module is available:
  
  ```powershell
  powershell
  Copy code
  Get-Module -Name Az.Sql -ListAvailable
  ```
  
  This command should list the `Az.Sql` module along with its version.
  
  **Check for Updates:** Regularly update your modules to benefit from the latest features and fixes:
  
  ```yaml
  powershell
  Copy code
  Update-Module -Name Az
  ```
