我有一个Visual Studio 2013 Update 3解决方案，其中包含一些自定义PCL库，然后是一个UniversalApp项目，其中包括Windows 8.1，WindowsPhone 8.1和共享位。我正在尝试编译WindowsPhone项目。共享项目包含一些模型，ViewModel，实用程序类，图像和某些样式。
我不确定发生了什么变化，因为它以前一直在起作用，但是现在我无法摆脱这个错误：
Error 8 The "GenerateResource" task failed unexpectedly.
System.IO.FileLoadException: Could not load file or assembly 'file:///C:\WINDOWS\Microsoft.Net\assembly\GAC_MSIL\Microsoft.Build.Tasks.v12.0\v4.0_12.0.0.0__b03f5f7f11d50a3a\Microsoft.Build.Tasks.v12.0.dll' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515)

我见过类似问题的帖子，但没有一个完全相同或有有效的修复程序。我尝试过的事情：
.suo文件已删除
在项目文件中添加了
<GenerateResourceNeverLockTypeAssemblies>true</GenerateResourceNeverLockTypeAssemblies>将
<loadFromRemoteSources enabled="true" />添加到devenv.exe.config文件删除UniversalApp项目并从头开始创建（尽管复制到某些文件中）
最佳答案
我也有类似的设置相同的问题（对不起，无法发表评论-积分不足）：
Win10 + VS2015
我将范围缩小到试图将MvvmCross合并到Win Phone 8.1项目中。我正在使用nuget引入3.2.1 mvvmcross库。我已经检查了这些dll，但是它们都没有“取消阻止”按钮（就好像它已经被取消阻止一样）。
如果我删除了dll引用，那么一切都会再次正常。
另外，以管理员身份运行也无济于事。明天我将把项目拖到Win8.1框中，看是否存在问题。
