Cannot compile solution in VS due "Attempted to access an unloaded AppDomain" -- how to pin it down?
提问by greenoldman
I have a C#/ASP.Net solution in VS (2008) with several projects within it. When I try to compile it I get one error only:
我在 VS（2008）中有一个 C#/ASP.Net 解决方案，其中包含多个项目。当我尝试编译它时，我只收到一个错误：
Attempted to access an unloaded AppDomain
试图访问卸载的 AppDomain
No line code, no project name, nothing. Just such error.
没有行代码，没有项目名称，什么都没有。就是这样的错误。
How can I pin down this error -- i.e. the cause, or even better -- how can I solve it and continue compilation?
我怎样才能确定这个错误——即原因，甚至更好——我怎样才能解决它并继续编译？
Thank you in advance.
先感谢您。

Shut down Visual Studio and reopen it. Then clean the Temp folder.
关闭 Visual Studio 并重新打开它。然后清理 Temp 文件夹。
For that press Windows+Rand type %Temp%and click Ok, then delete everything.
为此，请按Windows+R并键入%Temp%并单击“确定”，然后删除所有内容。

I am experiencing the same in Visual Studio 2012 - but ONLY on websites hosted on UNC share. My solution (when it occur) is to unload the web project and reload it again. Then in works for some time again.
我在 Visual Studio 2012 中遇到了同样的情况 - 但仅在托管在 UNC 共享上的网站上。我的解决方案（当它发生时）是卸载 web 项目并重新加载它。然后又工作了一段时间。
The problem as I recall it is, that the hosted UNC share (or the workstation trying to access it) is running an x86 version of Windows, which does not allow to many open network connections.
我记得的问题是，托管的 UNC 共享（或尝试访问它的工作站）正在运行 x86 版本的 Windows，它不允许许多开放的网络连接。
In my experience these sort of problems disappear on true x64 environments.
根据我的经验，这些问题在真正的 x64 环境中会消失。
Cheers.
干杯。

it means, there is something in WebConfig/AppConfig not compatible and cannot load.
这意味着，WebConfig/AppConfig 中存在不兼容且无法加载的内容。
For ex. ?f you published project, check app_data/publish profiles, delete them.
例如。?如果你发布了项目，检查 app_data/publish 配置文件，删除它们。

Check your .sln file first if it is conflicted then delete it and update your svn folder and rebuild your solution.
Rebuild your solution
如果您的 .sln 文件有冲突，请先检查它，然后将其删除并更新您的 svn 文件夹并重建您的解决方案。
重建您的解决方案

It's also possible that your unit test started up a thread but didn't close it. Ensure your threads are all closed before completion. It might be a good idea to verify all your unit tests are running and passing correctly.
也有可能您的单元测试启动了一个线程但没有关闭它。确保您的线程在完成之前全部关闭。验证所有单元测试是否正确运行和通过可能是一个好主意。
