Question

En mi proyecto Microsoft Surface, siempre recibo muchas de las siguientes excepciones:

La última excepción se lanza todo el tiempo hasta que detenga el programa. Ya comenté todo mi código, y ejecuté la aplicación con nada más que el código ya incorporado, pero sucede lo mismo.

¿Cómo puedo corregir eso? Solo encontré esta referencia:

http://www.mobydisk.com/softdev/techinfo/dotnetexceptions.html

Ahí dice:

La excepción que se produce cuando se devuelve un HRESULT no reconocido desde una llamada de método COM.

Pero no sé lo que esto significa ...

==== EDITAR ====

Seguí la sugerencia en la respuesta a continuación para depurar la excepción. Este es el informe detallado:

System.Runtime.InteropServices.COMException occurred
  Message=Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))
  Source=Microsoft.Surface.Shell.ShellApi
  ErrorCode=-2147221164
  StackTrace:
       at Microsoft.Surface.Shell.NativeMethods.CoCreateInstance(Guid rclsid, Object pUnkOuter, CLSCTX dwClsContext, Guid riid)
  InnerException: 

Y el debugador se detuvo en la llamada del constructor:

 public MainWindow()
        {
            InitializeComponent();

            // Add handlers for Application activation events
            AddActivationHandlers();

           // AssemblyParser parser = new AssemblyParser();
            //parser.parse();

           // DirSearch(@"C:/Users/Roflcoptr/Documents/Visual Studio 2008/Projects/TestClass.dll/");
        }

Paré justo al comienzo del constructor:

public MainWindow()

Answer 1

Me encontré con System.Runtime.InteropServices.COMException al abrir una solución de proyecto. A veces el usuario no tiene suficientes privilegios para ejecutar algunos métodos COM . Ejecuté Visual Studio como administrador y la excepción desapareció.

Answer 2

Su código (o algún código llamado por usted) realiza una llamada a un método COM que devuelve un valor desconocido. Si puedes encontrar eso, entonces estás a mitad de camino.

Podría intentar romper cuando se lanza la excepción. Vaya a Depurar> Excepciones ... y use la opción Buscar ... para localizar System.Runtime.InteropServices.COMException . Marque la opción para romper cuando se lanza y luego depurar su aplicación.

Con suerte, se romperá en algún lugar significativo y podrá rastrear y encontrar el origen del error.
