I am calling this line of code to get to the azure server:

var request = (HttpWebRequest)WebRequest.Create(uri);

and receive this exception. Does anybody know how to manage with it?

  • Ok, it seems the solution with LegacyWPADSupport helped, although we have different call stack. – Alex Blokha Mar 25 '13 at 15:58

    Yes. This solution helped http://stackoverflow.com/questions/13141434/httpclient-request-throws-ioexception/13745641#13745641, although we have different call stacks. – Alex Blokha Apr 08 '13 at 14:08

This solution helped HttpClient request throws IOException , although we have different call stacks.

You need to create these keys in registry.

Path: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework

Key:

name: "LegacyWPADSupport" type: "dword" data:00000000

Path: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\.NETFramework

Key:

name: "LegacyWPADSupport" type: "dword" data:00000000

    For completeness, the keys are in: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework and HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\.NETFramework – Rob Sep 25 '14 at 11:37
  • Thanks. The formatting have eaten the slash before the dot (\.). I've edited the answer, for correct display. – Alex Blokha Sep 25 '14 at 11:43
