Not an answer per se - but you're better off looking at the output window and seeing what it says there.

Also, to help with that you might want to look at your MSBuild verbosity - as shown on this screenshot (last two options):

<img src="https://i.stack.imgur.com/s5mGK.png" alt="Build options - Visual Studio">

Beware - the highest level generates a MASSIVE amount of information.

Finally - running <code>msbuild</code> from the solution folder in a command prompt will really nail the issue - because error messages and warnings come up in red and yellow respectively.

blocks|key|5958895|text|我找到了自己的解决方案，很简单：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5958896|当出现此错误时，保存项目并关闭VS+2013。之后，重新打开VS2013并打开最后一个项目。|offset|length|style|BOLD|5958897|它就像一种护身符。但每次都很烦人！|5958898|很多人在VS2010、VS2012和VS2013上报告了这个问题。|5958899|entityMap^0|0|0|1A|0|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|O|8|@$D|P|E|Q|F|G]]|9|@]|A|$]]|$1|H|3|I|5|6|7|R|8|@]|9|@]|A|$]]|$1|J|3|K|5|6|7|S|8|@]|9|@]|A|$]]|$1|L|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|M|$]]

I found my own solution and it is simple:

When this error occurs, save the project and close VS 2013. After that, re-open VS2013 and open the last project. 

It works like a charm. But it is very annoying every time!

Many people reported this problem in VS2010, VS2012 and VS2013.

blocks|key|4542916|text|可能是损坏的解决方案用户选项文件。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4542917|关闭该解决方案，删除其.suo+(VS2012%2B的.v12.suo)，重新打开该解决方案，Visual+Studio将构建一个新的解决方案。您将丢失StartUp项目、断点、书签、打开的文件、展开的项目/文件夹等。但与未构建的解决方案相比，这些都是次要的。|4542918|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|$]]

Could be a corrupt Solution User Options file.

Close the solution, delete its .suo (.v12.suo for VS2012+), reopen the solution, and Visual Studio will build a new one. You will lose the StartUp Project, breakpoints, bookmarks, which files are open, which projects/folders are expanded, etc. But that's all minor compared to the solution not building!

This error seems a bit generic to me. I also went through this situation, but I managed to solve it differently than any of the ones mentioned here. 
I have a project and several dependencies. And one of these dependencies has undergone a change.

When compiling the main project in debug mode, I verified that everything was ok.
However, switching to release mode and recompiling the problem occurred.<code>Rebuild all failed</code> and <code>0 Errors</code>

By analyzing the debug output, I encountered an error:

Although the build dependencies are configured correctly. When compiling in release mode, the main project did not find the new method created in the secondary project.
So I had to recompile each secondary project one by one in release mode. After that, I recompiled the main project and everything worked.

Hope it helps someone!

I was getting no feedback/messages/errors. Just that all projects failed to build.

I closed and tried again--I noticed an error saying "you are not authorized to access..."

I clicked on my account, re-entered my credentials, and rebuilt the solution.

Voila! I got what I am used to seeing when I build a solution -- plenty of errors in all their glory.

Hope this helps someone.

blocks|key|1836731|text|这是另一个对一些人来说可能听起来很熟悉的原因。我已经将一些代码集成到我的解决方案中，包装了一个DLL。随附的C#代码文件提供了一个很好的托管应用程序接口，并处理了访问该动态链接库的低级LoadLibrary内容。两者都有相同的基本名称，所以我有SomeName.cs和SomeName.dll。我只需将它放入任何项目中，它就会工作。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1836732|当我开始在不同的项目中使用它时，这并不是很好。我在多个项目中得到了DLL和包装器代码的副本。因此，我认为最好将包装器代码和DLL放到一个新的类库项目中，然后从其他项目中引用该新项目。|1836733|在我做完这些之后，我开始得到这个问题。构建进行得很顺利，直到最后一个阶段，然后就失败了，没有出现错误。输出只显示了成功。|1836734|问题出在包装类库项目的名称上。我对此使用了相同的基本名称(SomeName)。默认情况下，程序集名称是SomeName.dll，而我已经有一个这样的文件(要包装的DLL+)，因此我与输出文件有冲突。|1836735|将包装项目及其输出程序集重命名为SomeNameWrapper后，问题就消失了。|1836736|这可能不是您的确切原因，但似乎您也有一些名称冲突或部署问题。编译器不会给你一个错误也就不足为奇了，因为在编译阶段没有问题，问题从部署开始，显然这不是以一种明显的方式出现的。|1836737|entityMap^0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|O|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|P|8|@]|9|@]|A|$]]|$1|F|3|G|5|6|7|Q|8|@]|9|@]|A|$]]|$1|H|3|I|5|6|7|R|8|@]|9|@]|A|$]]|$1|J|3|K|5|6|7|S|8|@]|9|@]|A|$]]|$1|L|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|M|$]]

Here's yet another reason which may sound familiar to some. I had integrated some code into my solution that wrapped a DLL. The C# code file that came with it offered a nice managed API and handled the low-level LoadLibrary stuff to access the DLL. Both had the same base name, so I had SomeName.cs and SomeName.dll. I could just drop it into any project and it would work.

This wasn't so nice after a while as I started using it in different projects. I got copies of both the DLL and the wrapper code in multiple projects. So I figured it would be better to drop the wrapper code and the DLL into a new class library project and then reference that new project from other projects.

After I had done that, I started to get this issue. The build went well up until the very last stage and then failed without error. Output showed nothing but successes.

The problem was the name of the wrapping class library project. I used the same base name (SomeName) for this. By default the assembly name would be SomeName.dll and I already had one such file (the DLL to be wrapped), thus I had a conflict with output files.

After renaming the wrapping project and its output assembly to SomeNameWrapper, the problem went away.

This may not be your exact cause but it seems likely you have some name clash or deployment issue as well. And it is not surprising the compiler won't give you an error because there is no problem in the compilation phase, the trouble starts with deployment and apparently this does not come out in an obvious way.

blocks|key|5959421|text|我有相同的问题，原来的海报是显示0错误和重建所有成功。Output选项卡显示一条消息，指出引用的dll是使用更高版本的.NET框架生成的。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5959422|更改.NET框架以匹配解决了我遇到的0个错误的问题，并且所有重建都成功了。|5959423|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|$]]

I had the same problem the original poster was displaying with 0 errors and Rebuild all succeeded. The Output tab showed a message that a referenced dll was built with a higher version of the .NET Framework. 

Changing the .NET framework to match resolved the issue I was having with 0 Errors and Rebuild All succeeded.

blocks|key|2431401|text|解决方案:因为没有为调试设置先决条件仅为版本01设置-更改解决方案配置(在主屏幕中)设置(调试为发布)将解决方案平台设置为(任何CPU)+02-为调试设置先决条件(如果要继续调试模式)03-为所有项目设置目标平台版本|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2431402|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|$]]

The solution:
Because Prerequisites not set for debug set only for release
01-Change solution configuration ( in main screen )
set (debug to release)
set solution platform to (Any CPU)
02-Set Prerequisites for debug ( If you want to continue in debug mode )
03-set target platform version for all Projects

blocks|key|4543505|text|解决方案中包含的某些文件不在正确的目录中，或者您更改了应用程序中一个或多个目录的名称。在“解决方案资源管理器”的“设置”下，检查所有文件的列表，并删除SourcePath属性中未正确列出的文件。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4543506|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|$]]

Some of the files included in your solution are not in the correct directories, or you have changed the name of one or more directories in your application. In the solution explorer under Setup review the list of all files and remove those that are not properly listed in the SourcePath Property.

Why does Rebuild fail with no errors?
Since this morning, this error keeps showing up. I build the entire solution (25 C# managed projects) and a &quot;Rebuild All failed&quot; appears, but without any errors! (I have 13 warnings about COM not supporting Generics, but it's &quot;normal&quot; because one dll is exposed as COM.)

为什么重建失败而没有错误？从今天早上开始，这个错误就一直出现。我构建了整个解决方案(25个C#托管项目)，出现了一个“全部重建失败”，但没有任何错误！(我有13个关于COM不支持泛型的警告，但这是“正常的”，因为一个dll被公开为COM。)​​
