Instructs MSAL.NET to use an Azure regional token service. This setting should be set to either the string with the region (preferred) or to "TryAutoDetect" and MSAL.NET will attempt to auto-detect the region.

Client secret for the confidential client application. This secret (application password) is provided by the application registration portal, or provided to Azure AD during the application registration with PowerShell AzureAD, PowerShell AzureRM, or Azure CLI.

When set to true, MSAL will lock cache access at the ConfidentialClientApplication level, i.e. the block of code between BeforeAccessAsync and AfterAccessAsync callbacks will be synchronized. Apps can set this flag to false to enable an optimistic cache locking strategy, which may result in better performance at the cost of cache consistency. Setting this flag to false is only recommended for apps which create a new ConfidentialClientApplication per request.
