Specifies whether the provider checks your system proxy settings for existing proxy server configurations, rather than using a manually specified proxy server.

Data Type

bool

Default Value

true

Remarks

When this connection property is set to True, the provider checks your system proxy settings for existing proxy server configurations (no need to manually supply proxy server details).

This connection property takes precedence over other proxy settings. Set to False if you want to manually configure the provider to connect to a specific proxy server.

On Windows, the provider reads the proxy settings from the Internet Options in the registry, specifically the registry key HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\. On Windows 10 and later, this corresponds to the Proxy Settings found in the Windows Settings.

Note that these settings apply only to the current user of the machine. If you're running an application as a service, the provider does not read your own user's settings. You must instead manually supply the proxy settings in the provider's connection properties.

Note: This property is not supported for .NET Standard.

To connect to an HTTP proxy, see ProxyServer. For other proxies, such as SOCKS or tunneling, see FirewallType.
