Frage

I've enabled Enable Edit and Continue on the Web Properties page and it's also enabled in my configuration, yet Visual Web Developer 2008 Express Edition refuses to allow me to edit source files of an ASP.NET MVC project. I can edit the aspx file with no problem though.

Any ideas what's wrong or what's missing?

Lösung 2

My conclusion is that it just doesn't work.

If you are targeting x64 or Any CPU on a 64 bit machine you cannot use edit and continue. It only works when you are targeting x32.

I set my Platform target to x32 for the Debug configuration for this reason.

Remember after ticking "Enable Edit and Continue" in your project properties to Save your changes before building and testing your app. I made this mistake which cost me more time than I care to share!

enter image description here

It works fine at last in Visual Studio 2010 (MVC 4), below are all required steps to do it.

I can change e.g. action code in controller (when application is "paused" or stopped at break point) and all changes are automatically used after "Continue" or in step by step debugging.

Tools > Options > Debuging > Edit and Continue

Enable Edit and Continue

Tools > Options > Debuging > General

Enable "Brake all..", disable "Require source files..."

Build > Configuration Manager...

Set platform x86 for all projects

In Solution Explorer right click on main (web) project name > Properties

Enable "Edit and continue" for web

Change build output path to \bin

$Change build output path to "\bin"$

Source: Changes are not allowed if the assembly has not been loaded

You have to enable this on two places. See this blog post about Edit and continue for Web Application Projects (WAP)

To anyone running Vista 64 bit...

It may be that the IDE is not ready for Edit and Continue (EnC) web apps on Vista 64 bit without a tweek.

My situation: Migrated Web App to Vista 64 bit. Set platform to x86, set EnC in Tools/Options & Web properties, Debug flag in Web.Config, Debug mode set in Build configuration, etc, etc.

No joy - Could hit break points, inspect variables, etc, but could not EnC.

There were 7 Google hits on Msg "Changes are not allowed if the assembly has not been loaded". No new advice there for this situation though.

After trying numerous things finally tried changing the Build output path from "bin\x86\debug" to "bin\".

There was great joy across the land - Debug with EnC works now.
