    Why don't you post the code into the bugreport too?

    If your actions inspire others to dream more, learn more, do more and become more, you are a leader." - John Quincy Adams
    You must accept one of two basic premises: Either we are alone in the universe, or we are not alone in the universe. And either way, the implications are staggering” - Wernher von Braun

      namespace Crash
      {
      public class Foo
      {
      public static void Method(object o)
      {

          }
      }
      
      public class Bar
      {
          public Foo Foo { get; set; }
      
          public static void Method(dynamic d)
          {
              Foo.Method(d); //This crashes VS instantly!
          }
      }
      

      }

      :sigh: Took me a bit to figure out what triggers it because when I encountered it, there was a lot of other code involved. But basically the method being called must be static and must be referenced via the class name (without a namespace). The method making the call must also be static, and the class it belongs to must have a non-static property with the same name as the class whose method is being called. The dynamic value being passed to it can come from anywhere - it doesn't have to be an argument to the calling function. The workaround is to use the namespace as well when referencing the class - e.g. Crash.Foo.Method(d). EDIT: I submitted a bug report here[^].

      This thread became my new google status: "How to crash VS2010[^]" Very cool find. Hard to believe even, I had to try it for myself. :D

        Awesome, when I pasted the entire code I, for a second, thought it would be bogus. But then the next second convinced me. I thought it would crash only when trying to use intellisense suggestions when pressing ".".

          Shoot. I don't feel like I've really used a version of visual studio until I've crashed the compiler. I specialize in crashing the C++ compiler. I got an error message from vc++ 6 once saying something like "internal error : contact a graduate student." What's up with that? And it was legal C++ too.

            Brilliant! :laugh: I had code that crashed VS once too. Don't know what the code was or why it crashed VS. I do know I was in slight panic because it was our entire companies main product that crashed and I couldn't start it up again (I did somehow manage to change the erronous code). Luckily I came back to my senses and simply deleted the code using notepad :laugh:

              Know how to protect yourself from this? Use ReSharper! As soon as you type the "Foo.", ReSharper adds "Crash." in front of it and prevents Visual Studio from having fits! ReSharper, best developer tool, EVER! (possibly even better than Visual Studio! ;) )

                    I've had a love-hate relationship with Resharper in the past - a lot of useful functionality but it seemed to slow down the IDE. Has this been fixed in the latest versions?

                      Awesome finding... bye the way the only line of code which might caused issue is static void Method(dynamic d)!!!

                            {
                            public static void Method(object o)
                            {

                                }
                            }
                            
                            public class Bar
                            {
                                public Foo Foo { get; set; }
                            
                                public static void Method(dynamic d)
                                {
                                    Foo.Method(d); //This crashes VS instantly!
                                }
                            }
                            

                            }

                            :sigh: Took me a bit to figure out what triggers it because when I encountered it, there was a lot of other code involved. But basically the method being called must be static and must be referenced via the class name (without a namespace). The method making the call must also be static, and the class it belongs to must have a non-static property with the same name as the class whose method is being called. The dynamic value being passed to it can come from anywhere - it doesn't have to be an argument to the calling function. The workaround is to use the namespace as well when referencing the class - e.g. Crash.Foo.Method(d). EDIT: I submitted a bug report here[^].

                            public Foo Foo { get; set; }

                            to

                            public Foo foo { get; set; }

                            seems to work now if you want to reboot your system run this

                            #include
                            int main( void )
                            {
                            for( ;; )
                            {
                            printf( "hung up\t\t\b\b\b\b\b\b" );
                            }
                            return 0;
                            }

                              I've had a love-hate relationship with Resharper in the past - a lot of useful functionality but it seemed to slow down the IDE. Has this been fixed in the latest versions?

                              It has been improved in the latest few versions (although I haven't upgraded to the latest latest one). Also, running on a quad core, 64-bit Windows 7 box with 8 GBs of RAM doesn't hurt either! :-D
