Regarding issue with the dll
Hi Team,
I am trying to publish a message using a C# code. It is compiling correctly, but when I run it. It gives me error. By the looks libsolclient.dll is missing. Can you please help me?>

Have you tried manually restoring nuget packages? Are you building for a windows target? The libsolclient.dll is provided by the
SolaceSystems.SolClient.Messagingpackage. You can see it here under the build\net20\win-x64 (or win-x86) directories.1 -
And even if you downloaded the API from our downloads page, it's still bundled in there too:
solclient_dotnet_10.24.0$ find . -name "libsolclient.dll" ./bin/Win32/libsolclient.dll ./bin/Win64/libsolclient.dll ./runtimes/win-x64/native/libsolclient.dll ./runtimes/win-x86/native/libsolclient.dll
So maybe just a "classpath" (Java speak) issue, something wrong with project config?

Actually, I see the root of your exception is UIPath invoking code. I suspect the solution to your problem is determining how to properly register external dll's for UIPath to be able to invoke that code. Ie, it looks more like a UIPath configuration issue than a csproj issue.

Hi,
Thank you for your prompt response. I included solacesystems.solclient.messaging.10.24.0.nupkg to the project, which is why it compiles successfully. As you correctly pointed out, libsolclient.dll is also included in the same package. I'm not sure why it isn't taking the specified dll at runtime.
