  61号线：//具有附加属性加载log4net的线程（如果有）
62号线：受保护的内部空间AddExtendedThreadInfo（）{
63号线：如果（！_shellSettings.Value = NULL）{
64号线：ThreadContext.Properties [房客] = _shellSettings.Value.Name;
65号线：}
 

解决方案

刚刚发现，它似乎工作，如果在OrchardLog4netLogger.cs，我们替换

  _shellSettings =新懒人＆LT; ShellSettings＆GT;（LoadSettings）;
 

通过

  _shellSettings =新懒人＆LT; ShellSettings＆GT;（LoadSettings，
     System.Threading.LazyThreadSafetyMode.PublicationOnly）;
 

然后，所有线程都可以运行初始化方法。第一个线程来完成初始化设置懒惰实例的值

I I am using orchard 1.8.1 and try to install the theme Bootstrap and it gives me the following errors. Can anyone help me out?

Line 61:         // Load the log4net thread with additional properties if they are available
Line 62:         protected internal void AddExtendedThreadInfo() {
Line 63:             if (_shellSettings.Value != null) {
Line 64:                 ThreadContext.Properties["Tenant"] = _shellSettings.Value.Name;
Line 65:             }

解决方案

Just found that it seems to work if, in OrchardLog4netLogger.cs, we replace

_shellSettings = new Lazy<ShellSettings>(LoadSettings);

With

_shellSettings = new Lazy<ShellSettings>(LoadSettings,
     System.Threading.LazyThreadSafetyMode.PublicationOnly);

Then, all threads are allowed to run the initialization method. The first thread to complete initialization sets the value of the Lazy instance
