aspire deploy: az login check times out after ~10 seconds with no way to override

[DamianEdwards]

Description

When running aspire deploy targeting Azure Container Apps, the CLI performs an az account show check to verify the user is logged in. This check has a hard timeout of approximately 10 seconds that cannot be overridden.

On some machines, az account show can take 20-40 seconds due to factors outside the user's control (e.g., Windows Defender real-time scanning of Python's import chain, network latency to Azure AD for token refresh, etc.). When this happens, the Aspire CLI fails with a timeout error before az has a chance to respond.

Expected behavior

• The timeout for the az login check should be configurable (e.g., via a CLI flag or environment variable)
• Or the default timeout should be more generous (e.g., 60 seconds)
• Or the check should be skippable with a flag like --skip-login-check

Environment

• Aspire SDK: 13.2.1
• OS: Windows 11
• az CLI: 2.84.0 (Python 3.13.11)
• Target: Azure Container Apps (addAzureContainerAppEnvironment)

Repro

1. Have a machine where az account show takes >10 seconds (common with large Python import chains + real-time AV scanning)
2. Run aspire deploy targeting ACA
3. The deploy fails with a timeout before az responds

Workaround

None known. Restarting the machine sometimes helps by clearing the AV scan cache, but the issue recurs.
