C++/CLI sehexception message

Hi all.

I'm using the C++/CLI dll on the C# WinForm project.
To pass from the native code's exception message to C#, I have written the code as below.

#include "pch.h"
#include "ClassLibrary1.h"

using namespace ClassLibrary1;

void Class1::ThrowMessage()
{
	try
	{
		throw std::exception("Throw message");
		//SEHException message occurred!
	}
	catch (const std::exception& exc)
	{
		throw gcnew System::Exception(msclr::interop::marshal_as<System::String^>(exc.what()));
	}
}

The program works well.
But the 'System.Runtime.InteropServices.SEHException'(ClassLibrary1.dll) message is shown in the Visual Studio's output window.

If I check the SEHException option in the Visual Studio's Exception Option window, I could see the System.Runtime.InteropServices.SEHException: 'External component has thrown an exception.' message.

Is it ok to ignore this message?
If not, what should I do?

Here is my short sample code.

Please somebody help me.

Thank you.
