[Bug 37633] New: .NET's DownloadString method fails (due to RAS?)

https://bugs.winehq.org/show_bug.cgi?id=37633

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

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.

Hello folks,

I compiled the C# snippet into small console app and it works as expected.

--- snip ---
using System;

namespace bug37557
{
    class Program
    {
        static void Main(string[] args)
        {
            var xml = new
System.Net.WebClient().DownloadString("https://raw.githubusercontent.com/Epix37/Hearthstone-Deck-Tracker/master/Hea...");
            Console.WriteLine(xml);
        }
    }
}
--- snip ---

Your host network configuration is likely broken.

Thank you Anastasius. I was not aware wine had a host configuration. I will try
again with a modified config and reopen this if the bug persists.

The FIXED status is used when something in wine is fixed.

Anastasius, can you please attach the compiled exe? Did you run in mono?

Created attachment 50093

.NET 2.0 console app using System.Net.WebClient().DownloadString

Hello folks,

attached is the small .NET 2.0 executable (3K) for testing purpose.

VirusTotal (Google owned) scan report of the attachment:
https://www.virustotal.com/en/file/91061550f82895ba782e075e1ee1e26cf90bfe434...

You can easily (re)create it on your own by using 'winetricks dotnet20sdk' on
clean 32-bit WINEPREFIX which installs .NET Framework 2.0 and the SDK.

Create a text file 'bug37633.cs' with following content:

--- snip ---
using System;

namespace bug37557
{
    class Program
    {
        static void Main(string[] args)
        {
            String xml = new
System.Net.WebClient().DownloadString("https://raw.githubusercontent.com/Epix37/Hearthstone-Deck-Tracker/master/Hea...");
            Console.WriteLine(xml);
        }
    }
} 
--- snip ---

Compile it to .NET executable using the SDK C# compiler.

--- snip ---
$ wine "C:\windows\Microsoft.NET\Framework\v2.0.50727\csc.exe" /debug+
bug37633.cs
...
Microsoft (R) Visual C# 2005 Compiler version 8.00.50727.42
for Microsoft (R) Windows (R) 2005 Framework version 2.0.50727
Copyright (C) Microsoft Corporation 2001-2005. All rights reserved.
...
--- snip ---

--- quote ---
Did you run in mono?

No, since OP used MS .NET Framework (his app uses WPF so it's obvious).

Hello folks,

resolving here since OP didn't bother to update the status (being invalid).

Otherwise bugs like this will just bitrot away with no purpose and my time
wasted.
