ASP.NET-Debugging-Problem.

Question

Ich baue Websites in Visual Studio 2010 auf. Ich habe kürzlich auf ein neues dev-maschinelles Windows 7 64-Bit aktualisiert. Wenn ich jetzt eine Änderung einer Webseite ändert, muss ich aufhören, das Debuggen zu debuggen, Cassini zu töten, und wieder zu debuggen, bevor der neue Code wirksam wird.Ich hatte dieses Problem in XP nicht.

Dinge, die ich ausprobiert habe ...

• Compilation Debug="true" in Config-Datei
  
• Optionen-> Debugging-> Bearbeiten und Weiter ist aktiviert

  Ich bin nicht sicher, ob dies unter dynamischer Zusammenstellung folgt, oder editieren und fortzufahren - jede Hilfe würde geschätzt werden.

  Einer meiner Kollegen hat dieses Problem nicht.Er verfügt über ein identisches Setup für mich, mit demselben Projekt, derselben Build-Konfiguration (jeder 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).
