Problème de débogage ASP.NET

Question

Je construit des sites Web dans Visual Studio 2010. J'ai récemment mis à niveau vers une nouvelle machine de développement exécutant Windows 7 64 bits. Maintenant, lorsque je modifie une page Web, je dois arrêter de déboguer, tuer Cassini et recommencer à déboguer avant que le nouveau code ne prend effet.Je n'ai pas eu ce problème dans XP.

choses que j'ai essayées ...

• compilation debug="vrai" dans le fichier de configuration
• Options-> Débogage-> Modifier et continuer est activé

  Je ne suis pas sûr que cela suit sous la compilation dynamique ou modifier et continuer - toute aide serait appréciée.

  Modifier

  Un de mes collègues n'a pas ce problème.Il a une configuration identique à moi, en utilisant le même projet, la même configuration de construction (n'importe quel CPU)

Answer 1

As it turns out, this was my fault... I had experienced the dreaded "network BIOS command limit has been reached" issue. I found a post that recommended doing a regedit hack "HKLM\Software\Microsoft\ASP.NET\FCNMode = 1", well this basically turns off File Change Notifications. Changing this value to 2, and applying the changes recommended in knowledge base 810886 fixed both problems.

Answer 2

The reason is due to the change from a 32 bit os to a 64 bit os. The ability to change code while the application is running is unique to 32 bit code. In a 64 bit executable, this capability is removed.

This is known as "Edit and Continue". See this question for a good explanation of why this won't work on a 64bit executable:

Why doesn't Edit and Continue work on the x64 CLR?

EDIT: Clarification:

This isn't an issue with the OS, but rather the build of your code. If you have your build configuration set to "Any CPU", it will run under the architecture of your machine (x64 in your case). You should be able to force this to x86 and be able to use Edit and Continue.

Answer 3

64-bit apps can't be dynamically modified during debugging. To be able to do that you'll need to change your your build target 'x86'. Easy!

Just change it back (if you really need 64-bit assemblies).
