This happen often also if you are using a file references to binaries (instead of project references to code in your project), and the compiled binary that you are referencing falls out of sync with the corresponding source code on your machine. This can happen because you downloaded a new version of the binary from source control without the new source code that went with it, or you have a few versions of the binary on your machine and are referencing an old copy, etc. If this is indeed the problem, it's a good reason to use project references as much as it practical.

Pay attention to the "Output" window in VS. It will tell you what assemblies are loaded and when. You may see that an older version of your assembly somewhere in the folder is being loaded. 

For example if you have multiple assemblies and you are currently trying to break in one of the support assemblies, the CLR will handle the assembly resolving, which may load another assembly file than the one you have referenced in the project.

You can get this message when you are using an activator and the assembly you set the breakpoint into has not been loaded yet.

The breakpoint will resolve once the activator loads the assembly (assuming the assembly and debug symbols are up to date). A good place to look at is the modules window in the debugging menu. There you should look for the assembly which your file belongs too. First check that the assembly is loaded. Then, from where is it loaded? Then, is the symbols file loaded. Again, where is the symbols file loaded from? Finally check the versions of both.

This happens also when debugging a C++ project which loads a module that has been implemented with some CLR language (Managed C++, C# etc). In this situation the error message is misleading indeed.

I had caused this by opening a previous version (VS prompted to ask if I wanted to point to this instance in IIS debugging, I answered 'Yes'), then opening the current version (again responding to the IIS prompt with a 'Yes'), then attempting to debug in the previous version.

To solve, I merely closed and re-opened the previous and intended version, once again asserting it as the debugging source.

I suffered from this recently, and in my case I traced the problem back to something I was doing when testing: changing the system time. I'm not suggesting this is the case for everyone, but thought I'd mention it since it hasn't been mentioned already. It appears if you start moving the clock around between debug builds then it can get very confused about what order various files have been created it - I can only assume it is using file modified dates to determine if the source code is valid or not, and which binaries it needs to recompile.

It is also an option to re-save web.config to bump its modification time.

If your debugged process contains multiple appdomains and the assembly is loaded into both, and one of them is loading an old copy (usually something dynamically loaded like a plugin) the breakpoint can appear solid, but the thread that should hit the breakpoint is in the appdomain with the old assembly, and never hits. You can see what assemblies are loaded and their path in the module window.

It happened to me because I had other projects in the solution that weren't building.
After I unloaded those problematic projects (right-click on the project in the solution explorer -> Unload Project), rebuilt the solution and ran again -- the breakpoint was hit!

blocks|key|1708942|text|问题是您的调试信息与程序集不同步。解决方案很简单：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1708943|请转到您的bin文件夹，然后删除files|1708944|Rebuild|unordered-list-item|1708945|

The problem is that your debug info is not in sync with your assembly. The solution is simple:

<ol>
<li>Go to your bin folder</li>
<li>Remove the .pdb files</li>
<li>Rebuild</li>
</ol>

Should do the trick!

(the weird thing is, a rebuild without throwing away the .pdb files doesn't always work. I can see the modified date being updated, but still somewhere in the chain (VS2013 debugger, IIS, assembly cache) this change is not detected)

There is an almost imperceptible setting that fixed this issue for me. 
If there is a particular source file in which the breakpoint isn't hitting, it could be listed in 

<ul>
<li>Solution Explorer
<ul>
<li>right-click Solution
<ul>
<li>Properties
<ul>
<li>Common Properties
<ul>
<li>Debug Source Files
<ul>
<li>"Do not look for these source files".</li>
</ul></li>
</ul></li>
</ul></li>
</ul></li>
</ul></li>
</ul>

For some reason unknown to me, VS 2013 decided to place a source file there, and subsequently, I couldn't hit breakpoint in that file anymore. This may be the culprit for "source code is different from the original version".

blocks|key|1472821|text|检查解决方案中是否有多个同名文件。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1472822|这是我从别人手中接过的一个项目。断点列表中充满了Controller.cs中的行号，有些是活动的，有些不是。我发现了这个问题，并尝试了一些选项，但当我双击断点时，它们将我带到解决方案中的不同项目。因为这两个文件的名称是相同的，所以它们看起来是相同的，但事实并非如此。答案当然是忽略警告，因为如果你加载另一个文件，它们将变为活动状态。|1472823|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

Check to see if you have more than one file with that name in the solution.

I had this on a project that I took over from someone else. The breakpoint list was full of line numbers in Controller.cs, some active and some not. I found this question, and tried a few options, but when I double-clicked on the breakpoints, they took me to different projects within the solution. Because the files were called the same, they appear to be the same, but they aren't. The answer is of course then to ignore the warning, as they will become active if you get to load that other file.

blocks|key|5236237|text|有些情况下，重新编译和重新编译并不能帮助解决这个问题。其他可能的解决方案之一可能是从解决方案资源管理器中删除带有断点的源文件，然后重新添加它(例如，通过从文件夹中拖放)。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5236238|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

There are cases when recompiling and rebuild doesn't help to overcome this problem.
One of other potential solutions could be deletion of source file with breakpoints from Solution Explorer and adding it again (e.g. by drag and drop from folder).

For me; my website was running in an IIS Application under Default Website (<a href="http://localhost/myapp/" rel="nofollow">http://localhost/myapp/</a>) and the mapping for the IIS application was pointing to a disk path that was different to the source code I was working on. 

To resolve; remap your IIS Application to the same path as the source code you are building.

(This can happen if you have multiple versions of the same application running from different locations on your disk)

A new way to get this problem has appeared as of Visual Studio 2017 15.3.1 through 15.3.5. If you are using <a href="http://editorconfig.org/" rel="nofollow noreferrer">EditorConfig</a>, the <code>charset=utf8</code> option causes these symptoms.

So one fix is to comment out your <code>charset=utf8</code> line in the .editorconfig file.

I experienced this in a 32bit build on vs2017. 

Exactly none of the solutions worked for me. I restarted, I cleared IDE files, clean built solution, pulled from git repo and rebuilt the solution to no avail. 

I was pulling in a 64bit dependency from nuget and as soon as I used the assembly, the sources were not being built into the final executable anymore and instead the IDE cached sources were being built. 

I removed the nuget configuration, removed the referenced assembly, downloaded the source, built log4net manually, signed it, added it to a folder in my project, added reference to it, and I was able to debug again.

This was a pain, I hope it gets up in the answers list for all to see. 

Edit: There was no error during build despite having the option "prompt on build error" being turned on in the IDE settings.

I had the same issue in several projects in a layered architecture project and the problem was in configurations the build check box for the selected project hasn't been checked. so the issue was fixed for one project.

For one other layer it was giving this same trouble even the build is enable in the configurations. I did all the other options like restarting cleaning the project but non of them helped. Finally I unchecked the build checkbox for that particular project and cleaned and rebuild. the again marked the checkbox and did
the same. then the issue was fixed.

Hope this helps..

For VS Code users:

If you hit this while trying to debug an ASP .NET Core application, make sure that the build task defined in <code>tasks.json</code> and whose output you can see in the Debug Console pane, runs successfully.

The debugging configuration defined in <code>launch.json</code> which references this task, will for some reason (at least under some circumnstances) continue to execute the defined binary even if the build task has failed, and since the build task has failed, that binary is going to be the last successfully built assembly.

I got this problem after upgrading a project from netcoreapp2.0 to netcoreapp2.2.

I'd done this just by editing the <code>TargetFramework</code> entry in the <code>.csproj</code> file and neglected to also make the change <code>launch.json</code>.

<pre><code>"program": "${workspaceFolder}/src/MyProject/bin/Debug/netcoreapp2.0/MyProject.dll"
</code></pre>

This meant that VS Code was always loading the old 2.0 version of the project. I only discovered it after deleting everything in <code>/bin</code> and <code>/obj</code> and then it wouldn't run at all until I spotted the <code>2.0</code> in the path above.

Compile.

My issue was a bit stupid. I had two copy of my project and I mixed files in visual studio. 

Let s say you have <code>projectX</code> and <code>projectY</code>. These projects both contain <code>myFile.cs</code>. I opened <code>projectX</code> and edited <code>myFile.cs</code>. But this <code>myFile.cs</code> was belong to <code>projectY</code> . (It s possible to open files from different projects in visual studio) So in that case as warning says source code will be different than original.

I did the below for a similar issue:
Uncheck the option &quot;Enable Just My Code&quot; from the menu Debug -&gt; Option -&gt; General

When debugging in Visual Studio, sometimes I add a breakpoint but it's hollow and VS says "The breakpoint will not currently be hit. The source code is different from the original version." Obviously this prevents me from being able to debug.

What on earth does the message mean? What original version? If I've just opened up the solution and not made any changes whatsoever to the code, how can there be an 'original version'?

"The breakpoint will not currently be hit. The source code is different from the original version." What does this mean?

在Visual Studio中调试时，有时我会添加一个断点，但它是空的，VS会说“断点当前不会命中。源代码与原始版本不同。”显然，这会阻止我进行调试。这条信息到底是什么意思？什么原始版本？如果我只是打开了解决方案，而没有对代码做任何修改，怎么会有“原始版本”呢？

问“当前不会命中断点。源代码与原始版本不同。”这是什么意思？
