Can't edit and continue when using Visual Studio 2010 on a 64 bit machine, app targets x86

I'm having some problems with Edit and Continue when using Visual Studio 2010 on a Windows 7 64 bit machine. I've ensured the following

1. Edit and Continue is enabled under Tools>Options>Debuggi开发者_开发知识库ng>Edit and Continue
2. My solution platform is set to x86
3. My solution configuration is set to Debug
4. All my projects are building for Debug and x86
5. For all projects under Projects>Properties>Build the Optimize code is unchecked

When I hit a break point and try to edit I and confronted with the following message.

This is happening for me for all projects that I create whether they are WPF/Win Forms/VB.NET/C#/.NET 4/.NET 3.

Any ideas?

OK guys I figured it out. The other night I was playing around with IntelliTrace and changed the setting to collect call information. I didn't notice the warning on that page stating "Edit and continue is disabled when collecting Call Information"! See screen shot.

So I just disabled that and I was good to go. Thanks, that was really annoying.

Another solution is to check if any 3rd party references included and check their options for: Embed Interop Types. Set it to False.

---

One more option to check to enable the Edit and Continue Option.

Go to Project Properties and check the "Enable Edit and continue" Option

---

I found the problem!

In Advance Compile Option (in Project Properties) Uncheck Enable Optizimations

---

I had that also solved it by noticing that solution configuration was on release and not debug.

Changed it to debug and now I can edit and continue.

---

mine was working after i have done following

under advanced compile options set target CPU to x86 (was set to any cpu)

and its working fine now.

---

If you want to edit code after compile.

Just compile with ctrl + F5

---

another reason 1-Right click on Project file then Properties.
2-Compile --> advanced compile options.
3-Choose to generate "full" instead of "pdb-only" debug info.

At the msdn site,

http://msdn.microsoft.com/en-us/library/dd264944(v=vs.100).aspx

You can read about it:

"However, collecting calls and parameters will increase performance overhead, use additional disk space, and disable the Edit and Continue feature of the Visual Studio debugger."

---

Under Visual Studio 2013 edit and continue now works for the x64 platform.

---

Under Code Generation section, make sure option "Enable Function-Level linking" is set to Yes (/Gy).

---

I had that also solved it by noticing that solution configuration was on AnyCPU debug and Project was x86 debug

Changed it to x86 and now I can edit and continue.

I have a solution for a unique situation.

My Edit and Continue started failing in one function in VS2013. I discovered it was because I was doing some Office Interop to Excel in that function. I moved the Interop code to its own function and Edit and Continue started working in the original function again.
