Visual Studio Could not write to output file '...\obj\Debug\Foo.Bar.dll"
提问by Salaros
I've got this error while compiling a big c# solution in Visual Studio 2010. Each time after compilation I had to delete obj folder of one the projects used by this solution. Otherwise I got the following error:
我在 Visual Studio 2010 中编译大型 c# 解决方案时遇到此错误。每次编译后，我都必须删除此解决方案使用的项目之一的 obj 文件夹。否则我收到以下错误：
Could not write to output file '...\obj\Debug\Foo.Bar.dll'
The process cannot access the file because it is being used by another process
I've was looking for a solution all over the Internet and actually found/tried few of them.
我一直在互联网上寻找解决方案，实际上找到/尝试了其中的几个。
For example : a lot of people on dev forums were suggesting not to start the compilation while UserControl(in some other sources From) designer is opened.
例如：在开发论坛，很多人都建议不开始编译，而用户控件（在一些其他来源从设计师打开）。
Some other people used pre-build scriptsfor obj folder removal, this particular solution is acceptable, but if the issued project is a widely used library its recompilation will cause recompilation of "parent" projects.
其他一些人使用预构建脚本来删除 obj 文件夹，这个特定的解决方案是可以接受的，但是如果发布的项目是一个广泛使用的库，它的重新编译将导致“父”项目的重新编译。

Finally I've discovered a solution for this VS2010(SP1 too) "bug" and I want to share it with stackoverflow users.
最后，我发现了这个VS2010（也是 SP1）“bug”的解决方案，我想与 stackoverflow 用户分享。
In my case the problem was that csproj file was SELF-REFERENCING the locked '...\obj\Debug\Foo.Bar.dll'file. Crazy I know.
So I solved this annoying issue by removing the following line from .csprojfile:
就我而言，问题在于 csproj 文件是自引用锁定'...\obj\Debug\Foo.Bar.dll'文件。疯了我知道。所以我通过从.csproj文件中删除以下行来解决这个烦人的问题：
<Reference Include="Foo.Bar">
<HintPath>obj\Debug\Foo.Bar.dll</HintPath>
</Reference>

I initially found another solution to the problem as VS seems to lock the assembly in the obj\debug folder. I added a pre-build script to the project which fixed my problem.
我最初找到了另一个解决此问题的方法，因为 VS 似乎将程序集锁定在 obj\debug 文件夹中。我在项目中添加了一个预构建脚本来解决我的问题。
del "$(ProjectDir)obj\*.*" /S /F /Q
After seeing the answer given by Salaros, that was indeed the problem. I created a new usercontrol that uses a Server control from another project. For some reason VS sometimes creates a self-references to itself when you view the usercontrol in design mode. Even removing the self-reference fixes it until VS thinks its time to add the reference again. Haven't found an exact pattern for that part.
看到萨拉罗斯给出的答案，确实是这个问题。我创建了一个新的用户控件，它使用另一个项目中的服务器控件。出于某种原因，当您在设计模式下查看用户控件时，VS 有时会创建对自身的自引用。即使删除自引用也会修复它，直到 VS 认为是时候再次添加引用了。尚未找到该部分的确切模式。

In my case for me somehow the exe file was missing from release. Not sure how this happened. I replace it with a copy from debug and all was fine. I should have checked this sooner but never thought that the file would just turn up missing.
就我而言，不知何故，发行版中缺少 exe 文件。不知道这是怎么发生的。我用调试中的副本替换它，一切都很好。我应该早点检查这个，但从没想过文件会丢失。
