.net assembly interop exceptions handling

I am calling a .Net assembly from a Delphi project using COM interop.

Can I catch .Net exceptions in Delphi thrown by the assembly?

COM does not work with .NET exceptions but with HRESULT values. So there is no way you can catch .NET exceptions at Delphi side. You just receive a HRESULT with an error value. If you are lucky you will get an HRESULT with a specific error value so you know what has gone wrong, if you're unlucky, you will get some generic HRESULT value.
