Question

我有一个Asp.Net MVC应用程序，它有一些错误，其原因似乎无法追查。我认为它们是相关的，但我对ServiceStack不够熟悉，无法确定。

对于初学者，我一直看到抛出以下异常：

Method not found: 'ServiceStack.Text.JsConfigScope ServiceStack.Text.JsConfig.With(
System.Nullable`1<Boolean>, System.Nullable`1<Boolean>, 
System.Nullable`1<Boolean>, System.Nullable`1<Boolean>, 
System.Nullable`1<Boolean>, System.Nullable`1<Boolean>,
System.Nullable`1<Boolean>, System.Nullable`1<Boolean>, 
System.Nullable`1<ServiceStack.Text.DateHandler>,
System.Nullable`1<ServiceStack.Text.TimeSpanHandler>,
System.Nullable`1<ServiceStack.Text.PropertyConvention>,
System.Nullable`1<Boolean>, System.Nullable`1<Boolean>,
System.String, System.Func`2<System.Type,System.String>,
System.Func`2<System.String,System.Type>,
System.Nullable`1<Boolean>, System.Nullable`1<Boolean>,
System.Nullable`1<Boolean>, System.Nullable`1<Boolean>,
System.Nullable`1<Boolean>, System.Nullable`1<Boolean>,
System.Nullable`1<Int32>, ServiceStack.EmptyCtorFactoryDelegate,
System.String[])'.

这个方法实际上并没有在我自己的代码中调用。这个错误似乎在ServiceStack中继续发生。一个例子是尝试获得一个打字会话：

AppServiceBase.cs

using ServiceStack;

namespace MyWebProject.ServiceInterface
{
    public abstract class AppServiceBase : Service
    {
        public virtual UserSession UserSession
        {
            get { 
                return SessionAs<UserSession>(); // Throws an error when called
            }
        }
    }
}

那将给我一个像这样的堆栈跟踪：

[MissingMethodException: Method not found: 'ServiceStack.Text.JsConfigScope ServiceStack.Text.JsConfig.With(System.Nullable`1<Boolean>, System.Nullable`1<Boolean>, System.Nullable`1<Boolean>, System.Nullable`1<Boolean>, System.Nullable`1<Boolean>, System.Nullable`1<Boolean>, System.Nullable`1<Boolean>, System.Nullable`1<Boolean>, System.Nullable`1<ServiceStack.Text.DateHandler>, System.Nullable`1<ServiceStack.Text.TimeSpanHandler>, System.Nullable`1<ServiceStack.Text.PropertyConvention>, System.Nullable`1<Boolean>, System.Nullable`1<Boolean>, System.String, System.Func`2<System.Type,System.String>, System.Func`2<System.String,System.Type>, System.Nullable`1<Boolean>, System.Nullable`1<Boolean>, System.Nullable`1<Boolean>, System.Nullable`1<Boolean>, System.Nullable`1<Boolean>, System.Nullable`1<Boolean>, System.Nullable`1<Int32>, ServiceStack.EmptyCtorFactoryDelegate, System.String[])'.]
   ServiceStack.Redis.RedisClient.Exec(Func`2 action) +0
   ServiceStack.Redis.RedisClient.Get(String key) +241
   ServiceStack.Redis.RedisClientManagerCacheClient.Get(String key) +142
   ServiceStack.SessionExtensions.SessionAs(ICacheClient cache, IRequest httpReq, IResponse httpRes) +150
   ...Where it was called from and the rest of the stack.

这似乎发生在某处调用JsConfig.With()的任何事情。任何有关可能导致这种情况的见解都将非常感激。

每当方法签名在程序集之间不匹配或运行MissingMethodException时，依赖关系之间的版本可能不匹配，这会更新您的NuGet包解决。

ServiceStack库与相同的版本号一起以锁定步骤部署，因此您可以通过比较程序集版本信息来判断dll是否是相同的版本。

ServiceStack.Text.JsConfig.With（...）方法丢失了吗？
