Question

I am stuck with this error: while trying to use an old DLL in .Net Framework 4.0
If I change project target type to 3.5 then no error appears.
The strange is that all this happen Only while running inside VS 2010. If I run the executable from Windows Explorer, no problem occurs in 3.5 and 4.0.
Seems like some bug in vshost? VS 2010 Express, or .net framework?

UPDATE: This BUG only happen on WPF Standalone Application, if a change it to XBAP WPF I can use the dll without bigger problems, only a message telling it could no stop debugging.

I will leave this question open here, waiting to see if there is some progress on the connect.microsoft.com about this ticket.

Is there some way to make my .net4 app.config load this specific dll(CobreBemX.dll) using the .net 3.5 ?

I think this is some bug then i submitted it to https://connect.microsoft.com/VisualStudio/feedback/details/636697/comexception-was-unhandled-catastrophic-failure

Here is the code where it throws that COMException:

//Cria instância do objeto CobreBemX
CobreBemX.ContaCorrente _CobreBemX = new CobreBemX.ContaCorrenteClass();
//Monta arquivo de licença de teste para banco 001 carteira 18
_CobreBemX.ArquivoLicenca = @"C:\CobreBemX\Exemplos\Licencas\237-09.conf"; // THIS LINES CAUSES THE PROBLEM ON .NET 4.0    IF I CHANGE TARGET FRAMEWORK TO 3.5  NO PROBLEM HAPPENS

This is the stack trace:

System.Runtime.InteropServices.COMException was unhandled
  Message=Falha catastrófica
  Source=CobreBemX.ContaCorrente

For now this has no solution other than use XBAP
