有一个装配问题 [英] Having an assembly issue

问题描述

你好朋友，



在我的系统中我安装了一些NuGet包，当我尝试编译时收到如下错误信息：



类型'任务'存在于'System.Threading，Version = 1.0.2856.102，Culture = neutral，PublicKeyToken = 31bf3856ad364e35'和'mscorlib，Version = 4.0.0.0，Culture =中性，PublicKeyToken = b77a5c561934e089'





所以我删除了我通过Nuget安装的System.Threading，然后新的错误消息是as：



CS0012：类型'System.Threading.Tasks.Task`1'在未引用的程序集中定义。您必须添加对程序集的引用'System.Threading，Version = 1.0.2856.102，Culture = neutral，PublicKeyToken = 31bf3856ad364e35'。



在此之前我在框架4.5上运行，所以我升级到4.5 .1并将我的项目更改为4.5.1，但错误仍然与第二个错误相同。



那么，我该如何解决这个问题e？



以下是我正在处理的代码

  var  client =  new  HttpClient（）; 
  var  values =  new 列表< KeyValuePair< string，string>>（）; 
 values.Add（ new  KeyValuePair< string，string>（  task，task））; 
 values.Add（ new  KeyValuePair< string，string>（ 商家，merchant_id））; 
 values.Add（ new  KeyValuePair< string，string>（  ref，id））; 
  //  包含其他字段 
  var  content =  new  FormUrlEncodedContent（values）; 
 System.Threading.Tasks.Task< httpresponsemessage> t = client.PostAsync（  https://myepay.com/api/，content）; 
 t.Wait（）; 
  var  response = t.Result; 

我尝试了什么：



我升级到4.5.1并将我的项目更改为4.5.1



我编辑了web.config：

 <   system.web  >  
 <  编译    debug   =  true    targetFramework   =  4.5.1  /  >  

收件人：

 <   system.web  >  
 <  编译    debug   =  true    targetFramework   =  4.5 .1 >  
 <  程序集 >  
 <   add     assembly   =   System.Runtime，Version = 4.0.0.0，Culture = neutr al，PublicKeyToken = b03f5f7f11d50a3a  /  >  

更新



我尝试进一步解决了这个问题，我尝试了重定向问题建议。我是做了什么：



前

< runtime> 
< assemblyBinding applyTo =v2.0.50727xmlns =urn：schemas-microsoft-com：asm.v1> 
< dependentAssembly> 
< assemblyIdentity name =Newtonsoft.JsonpublicKeyToken =30ad4fe6b2a6aeedculture =neutral/> 
< bindingRedirect oldVersion =0.0.0.0-9.0.0.0newVersion =9.0.0.0/> 
< / dependentAssembly>< / runtime> 

后期

<运行时间> 
< assemblyBinding applyTo =v2.0.50727xmlns =urn：schemas-microsoft-com：asm.v1> 
< dependentAssembly> 
< assemblyIdentity name =Newtonsoft.JsonpublicKeyToken =30ad4fe6b2a6aeedculture =neutral/> 
< bindingRedirect oldVersion =0.0.0.0-9.0.0.0newVersion =9.0.0.0/> 
< / dependentAssembly> 
< dependentAssembly> 
< assemblyIdentity name =System.ThreadingpublicKeyToken =31bf3856ad364e35culture =neutral/> 
< bindingRedirect oldVersion =4.0.30319.18402newVersion =1.0.2856.102/> 
< / dependentAssembly> 
< / assemblyBinding> 
< / runtime> 

仍然会出现与以下相同的错误：

 CS0012：类型'System.Threading.Tasks.Task`1'在未引用的程序集中定义。您必须添加对程序集'System.Threading，Version = 1.0.2856.102，Culture = neutral，PublicKeyToken = 31bf3856ad364e35'的引用。

再次，我安装了一个NuGetNuGet包管理，它带来了许多依赖项。这可能是原因还是我做错了什么？

解决方案

我认为这是重定向问题读在其中 [ ^ ]关于它：



我有类似于你描述的东西 - 所以我很确定这是解决方案。这很糟糕，因为来自Projects设计时的app.config将在运行时被重定向覆盖，很难发现 - 所以看看你的RUNTIME！ app.config ...

目前UWP和Xamarin似乎不支持该库。



我'我有同样的问题，在检查后我发现使用System.Threading.Thread库的软件包实际上无法运行，因为该依赖项失败（即使微软称该软件包完全兼容）。

Hello Friends,

In my system I installed some NuGet packages, when I tried to compile I got an error message as below:

"The type 'Task' exists in both 'System.Threading, Version=1.0.2856.102, Culture=neutral, PublicKeyToken=31bf3856ad364e35' and 'mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'


so I removed the "System.Threading" I installed via Nuget, then the new error message is as:

CS0012: The type 'System.Threading.Tasks.Task`1' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Threading, Version=1.0.2856.102, Culture=neutral, PublicKeyToken=31bf3856ad364e35'.

Before this I was running on framework 4.5, so I upgraded to 4.5.1 and change my project to 4.5.1, but the error is still the same as the second error.

So, how do I resolve this issue?

Below is the code I am working on

var client = new HttpClient();
   var values = new List<KeyValuePair<string, string>>();
   values.Add(new KeyValuePair<string, string>("task", task));
   values.Add(new KeyValuePair<string, string>("merchant", merchant_id));
   values.Add(new KeyValuePair<string, string>("ref", id));
   // include other fields
   var content = new FormUrlEncodedContent(values);
                    System.Threading.Tasks.Task<httpresponsemessage> t = client.PostAsync("https://myepay.com/api/", content);
                    t.Wait();
                    var response = t.Result;

What I have tried:

I upgraded to 4.5.1 and change my project to 4.5.1

I edited the web.config from:

<system.web>
    <compilation debug="true" targetFramework="4.5.1"/>

To:

<system.web>
    <compilation debug="true" targetFramework="4.5.1">
      <assemblies>
        <add assembly="System.Runtime, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"/>

UPDATED

I tried further to resolve the issue, I tried the redirecting ask suggested.below is what I did:

Former

<runtime>
    <assemblyBinding appliesTo="v2.0.50727" xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-9.0.0.0" newVersion="9.0.0.0" />
      </dependentAssembly></runtime>

Latter

<runtime>
    <assemblyBinding appliesTo="v2.0.50727" xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-9.0.0.0" newVersion="9.0.0.0" />
      </dependentAssembly>
    <dependentAssembly>
        <assemblyIdentity name="System.Threading" publicKeyToken="31bf3856ad364e35" culture="neutral" />
             <bindingRedirect oldVersion="4.0.30319.18402" newVersion="1.0.2856.102" />
      </dependentAssembly>
    </assemblyBinding>
  </runtime>

still it gives the same error as:

CS0012: The type 'System.Threading.Tasks.Task`1' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Threading, Version=1.0.2856.102, Culture=neutral, PublicKeyToken=31bf3856ad364e35'.

And again, I installed a NuGet "NuGet Package Management" and it came with many dependencies. could that be the cause or what else is have I done wrong?

解决方案

I think this is the "Redirect Problem" read here[^] about it:

I had something similar to what you described - so I'm pretty sure this is the solution. It's nasty because your app.config from the Projects design time will be overwritten at runtime with the Redirects, hard to spot - so have a look at your RUNTIME! app.config...

At the moment UWP and Xamarin don't appear to support that library.

I've had the same issues, and after checking around I found that packages that use the System.Threading.Thread library can't actually run because that dependency fails(Even when Microsoft says the package is perfectly compatible).
