软件包Microsoft.AspNet.WebApi.Client 5.2.3中的System.Net.Http.Formatting.dll。似乎不起作用 [英] System.Net.Http.Formatting.dll in package Microsoft.AspNet.WebApi.Client 5.2.3. doesn't seem to work

问题描述

我有一个针对.net 4.5.1框架的vb.net类库项目。我在Windows 7主页上使用Visual Studio 2013社区版。

I have a vb.net class library project targeting .net 4.5.1 framework. I am using Visual Studio 2013 community edition on Windows 7 home.

该项目是一个使用webapi 2 REST API的库。

The project is a library consuming a webapi 2 REST API.

作为指南我使用的是这个例子

As a guide I am using this example

http://www.asp.net/web-api/overview/advanced/ call-a-web-api-from-a-net-client

http://www.asp.net/web-api/overview/advanced/calling-a-web-api-from-a-net-client

项目的packages.config如下：

Project's packages.config is the following:

<?xml version="1.0" encoding="utf-8"?>
<packages>
    <package id="Microsoft.AspNet.WebApi.Client" version="5.2.3" targetFramework="net451" />
    <package id="Newtonsoft.Json" version="7.0.1" targetFramework="net451" />
</packages>

项目的程序集引用是：

Project's assemblies references are:

    Newtonsoft.Json, Version=7.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed, processorArchitecture=MSIL
    System
    System.Data
    System.Net.Http
    System.Net.Http.Formatting, Version=5.2.3.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL
      <HintPath>..\..\..\..\packages\Microsoft.AspNet.WebApi.Client.5.2.3\lib\net45\System.Net.Http.Formatting.dll</HintPath>
    System.Xml
    System.Core
    System.Xml.Linq
    System.Data.DataSetExtensions

app.config文件是：

app.config file is:

    <?xml version="1.0" encoding="utf-8"?>
    <configuration>
     <runtime>
       <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
         <dependentAssembly>
           <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral" />
           <bindingRedirect oldVersion="0.0.0.0-7.0.0.0" newVersion="7.0.0.0" />
         </dependentAssembly>
       </assemblyBinding>
     </runtime>
     <startup><supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5.1" />
     </startup>
    </configuration>

问题是Microsoft中定义的System.Net.Http.HttpClient扩展。未加载AspNet.WebApi.Client.5.2.3\lib\\\
et45\System.Net.Http.Formatting.dll，因此函数如$

The problem is that System.Net.Http.HttpClient extensions defined in Microsoft.AspNet.WebApi.Client.5.2.3\lib\net45\System.Net.Http.Formatting.dll aren't loaded so functions like

    System.Net.Http.HttpClientExtensions.PostAsJsonAsync（Of T）



和



     System.Net.Http.HttpClientExtensions.PostAsXmlAsync（Of T）



不可用。



我发现有几个相关问题就像这样一个

    System.Net.Http.HttpClientExtensions.PostAsJsonAsync(Of T)

and

    System.Net.Http.HttpClientExtensions.PostAsXmlAsync(Of T)

aren't available.

I found several related questions is SO like this one

http://stackoverflow.com/questions/19158378/httpclient-not-supporting-postasjsonasync-method-c-sharp

http://stackoverflow.com/questions/19158378/httpclient-not-supporting-postasjsonasync-method-c-sharp

但是评论中提供的答案和建议对我不起作用。



我尝试了各种互联网资源的其他建议，例如：示例替换在Microsoft.AspNet.WebApi.Client包中找到的System.Net.Http.Formatting.dll的引用与扩展程序集区域中找到的引用但是也没有工作
。



现在我被卡住了，我不知道如何解决这个问题。任何帮助都将受到高度赞赏。

but the provided answers and suggestions in comments didn't work for me.

I tried several other recommendations from various internet sources, like for example replacing the reference of System.Net.Http.Formatting.dll found in Microsoft.AspNet.WebApi.Client package with the one found in the extensions assemblies area but didn't work either.

Now I am stuck and I don't know how to solve this. Any help will be highly appreciated.
