Bug ID: 37633
           Summary: .NET's DownloadString method fails (due to RAS?)
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: P2
         Component: rasapi32
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

Using: wine-1.7.31

I am trying to run a .NET app that I have the source code to.

The C# code looks as follows:
var xml = new
WebClient().DownloadString("https://raw.githubusercontent.com/Epix37/Hearthstone-Deck-Tracker/master/Hea...");

I see these messages appear in my console:

fixme:ras:RasEnumConnectionsW (0x7804d68,0x33e43c,0x33e440),stub!
fixme:ras:RasEnumConnectionsW RAS support is not implemented! Configure program
to use LAN connection/winsock instead!
fixme:ras:RasConnectionNotificationW (0xffffffff,0x2cc,0x00000003),stub!
fixme:winhttp:get_system_proxy_autoconfig_url no support on this platform
fixme:winhttp:WinHttpDetectAutoProxyConfigUrl discovery via DHCP not supported

And then the C# stack trace which bubbles, originating from DownloadString:

########## 11/25/2014 8:58:27 PM ##########
System.Windows.Markup.XamlParseException: The invocation of the constructor on
type 'Hearthstone_Deck_Tracker.MainWindow' that matches the specified binding
constraints threw an exception. ---> System.AccessViolationException: Attempted

I am not positive what the exact error here is, although it is pretty severe
that a simple .NET web-related download method fails. Any insight to get this
to work would be appreciated.
