             ThrowSwallowThirdParty();
         }

         [Test]
         public void Test_ThrowSwallowLocal()
         {
             ThrowSwallowLocal();
         }

         public void ThrowSwallowThirdParty()
         {
             ThirdPartyLibrary.ThrowEmbedded();
         }

         [DebuggerStepThrough]
         [DebuggerNonUserCode]
         [DebuggerHidden]
         public void ThrowSwallowLocal()
         {
             try
             {
                 throw new Exception();
             }
             catch (Exception e)
             {
             }
         }
     }

     // imagine this is a 3rd party library provided in a dll which I am referencing
     internal static class ThirdPartyLibrary
     {
         public static void ThrowEmbedded()
         {
             try
             {
                 throw new Exception();
             }
             catch (Exception e)
             {
             }
         }
     }
 }

As per here and here I understand you can use the [DebuggerHidden] attribute to prevent the debugger from stopping at a swallowed exception even if it is told to break on all thrown exceptions. This works for Test_ThrowSwallowLocal(). However I would like to duplicate this when calling code in a 3rd party library which is throwing and swallowing its own exceptions – which I am trying to emulate in Test_ThrowSwalloThirdParty() – at the moment the debugger continues to break at the exception throw.

Is there a way to avoid this without editing the ThirdPartyLibrary code (which I cannot easily do?)

I would look into the Just My Code Option in VS
