Creating Named Pipe in protected mode.

Thx for your help.
1. I have host application where I created named pipe like this: 

Task.Factory.StartNew(() =>
                {
                    var server = new NamedPipeServerStream("foo");
                    server.WaitForConnection();
                    StreamWriter writer = new StreamWriter(server);

                    while (true)
                    {
                        writer.WriteLine("hello");
                        writer.Flush();
                    }
                });

2. In Adobe plug-in (ACCB1 ASBool ACCB2 PluginInit(void) function) I tried to connect to it :

HANDLE hPipe;

hPipe = CreateFile(TEXT("\\\\.\\pipe\\foo"),
		GENERIC_READ | GENERIC_WRITE,
		0,
		NULL,
		OPEN_EXISTING,
		0,
		NULL);

if (hPipe != INVALID_HANDLE_VALUE)
{
 // do stuff 
}

And I always get INVALID_HANDLE_VALUE result. 

Add setting in reg. (HKLM_Software/Policies/Adobe/Acrobat Reader/DC/FeatureLockDown/bUseWhitelistConfigFile = 1)
In ProtectedModeWhitelistConfig.txt file which placed in C:\Program Files (x86)\Adobe\Acrobat Reader DC\Reader folder I added this lines : 

FILES_ALLOW_ANY = pipe\*
NAMEDPIPES_ALLOW_ANY = \.\pipe\foo

I tried different string patterns in NAMEDPIPES_ALLOW_ANY  section :
\\\\.\\pipe\\foo.*

\\\\.\\pipe\\foo
pipe\foo.*
pipe\foo
pipe\*
\\\\.\\pipe\\*
\.\pipe\*

Tried put only pipe name. 
As well as at FILES_ALLOW_ANY  section.
Also i enabled logs 

Go to HKEY_CURRENT_USER\Software\Adobe\Acrobat Reader\(version)\Privileged.
Right click and choose New > REG_SZ Value.
Create tBrokerLogfilePath.
Right click on tBrokerLogfilePath and choose Modify.
Set the value. For example: C:\DOCUME~1\<username>\LOCALS~1\Temp\BrL4FBA.tmp.

Log : 

[03:10/16:53:53] NtCreateFile: STATUS_ACCESS_DENIED
[03:10/16:53:53] real path: \??\pipe\foo
[03:10/16:53:53] Consider modifying policy using these policy rules: FILES_ALLOW_ANY or FILES_ALLOW_DIR_ANY

I got this message every time with different string pattern.
