Bottom Line Up Front

Is it possible to create a self-contained .NET 6 executable written in C# with a dependency on a C++ library?

Summary

I have created self-contained .NET 6 executable. When it runs, it crashes with a c0000005 (access violation) error.

The program starts without any problem. The crash appears to happen the moment that it needs to create an object that is supplied by a dependency that consists of C# wrappers of some C++ code.

I cannot find any documentation to verify my suspicions, but does .NET 6 not support creating self-contained executables with C++ dependencies? Or perhaps there is something special I need to do to make self-contained .exes work with C++-based dependencies?

By the way, the program runs just fine if I run the non–self-contained version of the .exe.

Some More Detail

The dependency that is giving me trouble is Pelco's VxSdk.NET. It only supports 64-bit assemblies/executables, so I am only building a 64-bit version of the .exe. Perhaps it's not a problem with C++-based libraries in general, just with this one in particular?

Code Sample

Here is a quick code sample to illustrate:

using VxSdkNet;

Console.WriteLine("Everything is fine here\n\n");
Console.Out.Flush();

await Task.Delay(TimeSpan.FromSeconds(1));

Console.WriteLine("If this is a self-contained .exe ...");
Console.WriteLine("... the line after the await crashes with a c0000005 (access violation)\n\n");
Console.Out.Flush();

await Task.Delay(TimeSpan.FromSeconds(1));

using var videoXpert = Connect();

await Task.Delay(TimeSpan.FromSeconds(1));

Console.WriteLine("If this is NOT a self-contained .exe ...");
Console.WriteLine("... we get here just fine");

static VXSystem Connect()
{
    const string ip = ...;
    const int port = ...;
    const bool useSSL = ...;
    const string licenseKey = ...;
    const string username = ...;
    const string password = ...;

    var videoXpert = new VXSystem(ip, port, useSSL, licenseKey);
    var result = videoXpert.Login(username, password);
    return videoXpert;
}

Output

Here is the output from the self-contained .exe:

Everything is fine here


If this is a self-contained .exe ...
... the line after the await crashes with a c0000005 (access violation)
