[help] Has anyone tried to call this library in C#?

[BruceQiu1996]

Is there an already existing issue for this?

• I have searched the existing issues

Expected behavior

Our company has done some host computer programs in C#, but we need to use fastdds to communicate with some other programs。So our C++ team encapsulates a DLL and exposes the publish and subscribe interfaces for us to call.

Current behavior

We have found that after using it for a long time or occasionally, the program crashes.I saw some memory errors in the Windows logs, probably because unsafe memory was accessed, as shown in the figure

Steps to reproduce

Just c# call c++ dll for fastdds

Fast DDS version/commit

2.12.1

Platform/Architecture

Windows 10 Visual Studio 2019

Transport layer

Default configuration, UDPv4 & SHM

Additional context

XML configuration file

No response

Relevant log output

Network traffic capture

Hi @BruceQiu1996, thanks for using Fast DDS!

I am moving this issue to the corresponding discussion forum since Fast DDS 2.12 is no longer a maintained version and the issue might be related with the custom C# wrapper you are using.
