Working in .NET platform and configuring proxy server

Commonly when developing under .NET platform you do not need to specify proxy server settings explicitly in your application. The Framework should autodetect the WinINET proxy when the .NET application starts (Internet Properties > Connections > LAN settings > Proxy server).

If you want to override default behavior please see the following articles on MSDN:
