尝试在VS2013中以调试模式编辑代码时出错

Question

I'm a C# programmer and recently I've installed Visual Studio 2013. The problem is when i set a break point or get an error and trying to edit the codes while debugging I get this error and I couldn't find the same error searching on Google.

Changes are not allowed for this module as it was not built for changes while debugging or the target .NET runtime version does not support it

I also tried to check the options on Tools -> Options -> Debugging -> Edit and Continue , But didn't help.

Any idea what the problem is?

Answer 1

To edit a C# program while you're running it in Visual Studio 2013:

1. Go to Project, Properties, Build.
2. Set Platform target: x86
3. Disable "Optimize code"
4. Set Advanced, Debug Info: Full

Answer 2

我遇到了同样的问题，发现顶部栏上的“解决方案配置”已更改为Release from Debug，因为我将最后一个版本构建到Release文件夹中。更改回调试模式将解决问题。

Answer 3

The code your probably modifying is included in the exception. Since, your code is not posted here, I can't say. So please refer to this link and check whether it is really not allowed.

Answer 4

我们在Visual Studio 2013中遇到了同样的问题，在我们的例子中，这是因为我们在“项目设置”的“调试”选项卡上禁用了Visual Studio托管过程。

I just had the same problem and found a solution that worked for me right here after trying 100 other things:

1.) execute VsPerfCLREnv /globaloff 2.) reboot your computer

Answer 6

In a Web Forms application, I initially received the "Changes are not allowed for this module as it was not built for changes while debugging or the target .NET runtime version does not support it" error message. Based on suggestions above I completed the following:

1. Right click the project name, just under the Solution name in Solution Explorer and select Properties, the "Build" tab
2. Set Platform target: x86 (Note, for me this was already set)
3. Disable "Optimize code"
4. Click the “Advanced” button (near bottom) and set, Debug Info: Full

I tried to modify code, but then I received the "Edit and Continue" window stating "Changes are not allowed while code is running."

Here was the important part: I can only make changes while stopped at a breakpoint. If the page is loaded, I get that same "Changes are not allowed..." message. So set a breakpoint to a line above where you need to make the change, complete the update and you should be set.

Or (as I subsequently discovered) another way to modify code without using a breakpoint is to click in Visual Studio "Debug/Break All" (Ctrl+Alt+Break), make your change and then press F5 or click the "Continue" button. (Using this method you will might need a page refresh to see the mods.)

Answer 7

It worked for me by unchecking "Enable optimizations" option.

You can try

1. Right click 'Solution' in the Solution Explorer.
2. Select Properties.
3. Choose Configuration Properties from the left menu.
4. Select 'Debug' from the dropdown list in the upper-left corner labeled 'Configuration:'.
