运行 WCF 数据服务时出现 Microsoft.Data.Services 版本问题

Question

我收到以下错误：

Could not load file or assembly 'Microsoft.Data.Services, Version=5.6.2.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

但是当我去检查我的 Packages.config 时：

<?xml version="1.0" encoding="utf-8"?>
<packages>
  <package id="Microsoft.CodeDom.Providers.DotNetCompilerPlatform" version="2.0.1" targetFramework="net472" />
  <package id="Microsoft.Data.Edm" version="5.6.4" targetFramework="net472" />
  <package id="Microsoft.Data.OData" version="5.6.4" targetFramework="net472" />
  <package id="Microsoft.Data.Services" version="5.6.4" targetFramework="net472" />
  <package id="Microsoft.Data.Services.Client" version="5.6.4" targetFramework="net472" />
  <package id="Microsoft.OData.EntityFrameworkProvider" version="1.0.0-beta2" targetFramework="net472" />
  <package id="System.Spatial" version="5.6.4" targetFramework="net472" />
</packages>

它显示了我上面的文件，我需要更改版本吗？如果是，那么我该如何改变它？我尝试通过掘金它没有工作。

我检查了我的C:\Program Files\Microsoft SDKs\Azure\.NET SDK\v2.9\bin\plugins\Diagnostics，那里有 5.6.2 版本的 dll，我用 5.6.4 替换了它们，但仍然遇到同样的错误。

更新：

我在下面的 web.config 中进行了更新：

<runtime>
        <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
            <dependentAssembly>
                <assemblyIdentity name="Microsoft.Data.Services" publicKeyToken="31bf3856ad364e35" culture="neutral" />
                <bindingRedirect oldVersion="0.0.0.0-5.6.2.0" newVersion="5.6.4.0" />
            </dependentAssembly>
        </assemblyBinding>
    </runtime>
  <system.web>
    <compilation debug="true" targetFramework="4.7.2" />
    <httpRuntime targetFramework="4.7.2" />
  </system.web>

它将输出更改为：

日志显示以下问题：

Answer 1

错误：服务器在处理请求时遇到错误。看 服务器日志了解更多详情

只要 WCF 服务出现任何问题，就会出现此问题。 所以查看问题的更多细节，你需要在servicedebug标签中将includeexceptiondetailInfaults属性true。

<Service Behavior>
 <Behavior Name="myServiceBehavior">
  <servicedebug includeexceptiondetailinfaults="true" />
 </Behavior>
</Service Behavior>

您也可以将类属性添加到服务类。

无法加载文件或程序集“Microsoft.Data.Services， 版本=5.6.2.0，文化=中性，PublicKeyToken=31bf3856ad364e35' 或 它的依赖项之一。定位程序集的清单定义 与程序集引用不匹配。 （HRESULT 的例外情况： 0x80131040)

对于这个问题，首先检查你的输出目录中这个dll的版本。然后

• 清理您的解决方案
• 删除所有 obj 和 bin 目录
• 从整个解决方案中卸载此软件包
• 确保在 GAC 中删除此文件：&userprofile%.nuget\packages\microsoft.data.services - 确保删除整个目录
• 现在您可以从 NuGet 安装所需的版本
