In my c# application, I am trying to create a simple test publisher and 
subscriber given in mnb.ociweb.com/mnb/MiddlewareNewsBrief-201006.html 
website. If I only add the wrapper dll to my publisher application, it 
crashes with an error message of WSAStartup. I have handled this error 
in my code and after doing that I get another run-time error at line 
number 413 reactor_task_.wait_for_startup().And the output windows shows 
the following-

Step into: Stepping over non-user code 
'DDS::DomainParticipantQos::DomainParticipantQos'
The program '[1656] ConsoleApplication1.exe: Managed (v4.0.30319)' has 
exited with code -1073741819 (0xc0000005).

And my call stack while debugging is as follows-

OpenDDS_Dcps.dll!OpenDDS::DCPS::Service_Participant::get_domain_participant_factory(int 
&argc, char ** argv) Line 413
[External code]
Message_DDSImpl.dll!DDSNet::DDSBase(int argc, char **argv) Line 54 + 
0x22 bytes
Message_DDSImpl.dll!DDSNet::DDSImpl(int argc, char **argv) Line 81 +

Message_DDSImpl.dll!DDSNet::DDSNet() Line 113 + 0x2d bytes
ConsoleApplication1.exe!ConsoleApplication1.Program.Main(string [] args) 
Line 55 + 0x21 bytes

I have also used dependency walker to check dependency of my executable, 
it gives the following error-

second chance exception 0xC0000005[Access violation] occured in 
"NTDLL.DLL" at address 0x0000000077892F86

As per your earlier mail on the same subject dated 12/30/2016 08:37 pm 
IST, you have mentioned to rebuild OpenDDS with /clr support by doing 
the changes suggested by David Cornellius. I have followed those 
instructions and rebuild OpenDDS with /clr support. In addition to this, 
I have build the wrapper library successfully and added it to my c# 
application.

     I am looking forward to your reply.
