以前版本的 Autofac 可以工作,但由于他们切换到使其成为可移植类库,它不会加载。
我尝试应用此处列出的修复程序(KB2468871),但它告诉我不需要它。
当我将 Autofac.dll 文件移动到与可执行文件相同的位置时,错误消失了。当它从外部 DLL 加载它时,它加载得很好。
为什么它不能作为嵌入式 DLL 工作?
这是一个例外:
System.IO.FileNotFoundException: Could not load file or assembly 'System.Core, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e, Retargetable=Yes' or one of its dependencies. The system cannot find the file specified.
Stack trace:

如果有帮助,这里是 .csproj 文件的一部分,它将 DLL 嵌入到可执行文件中:
<Target Name="AfterResolveReferences">
<ItemGroup>
<EmbeddedResource Include="@(ReferenceCopyLocalPaths)" Condition="'%(ReferenceCopyLocalPaths.Extension)' == '.dll'">
<LogicalName>%(ReferenceCopyLocalPaths.DestinationSubDirectory)%(ReferenceCopyLocalPaths.Filename)%(ReferenceCopyLocalPaths.Extension)</LogicalName>
</EmbeddedResource>
</ItemGroup>
...这里是 EntryPoint 类:
internal static class EntryPoint
{
[STAThread]
private static void Main(params string[] args)
{
AppDomain.CurrentDomain.AssemblyResolve += (sender, e) => loadEmbeddedAssembly(e.Name);
Bootstrapper.Run(args); // must call separate class when using embedded assemblies
}
private static Assembly loadEmbeddedAssembly(string name)
{
var container = Assembly.GetExecutingAssembly();
var path = new AssemblyName(name).Name + ".dll";
using (var stream = container.GetManifestResourceStream(path))
{
if (stream == null)
{
return null;
}
var bytes = new byte[stream.Length];
stream.Read(bytes, 0, bytes.Length);
return Assembly.Load(bytes);
}
}
}
