I am getting the following error:

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)

But when I go and check my Packages.config:

<?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>

It showing me above file, Do I need to change the version ? If yes then how I can change it? I tried through nugget it didn't work.

I checked in my C:\Program Files\Microsoft SDKs\Azure\.NET SDK\v2.9\bin\plugins\Diagnostics there are 5.6.2 version dlls are there, I replaced them with 5.6.4 but still getting the same error.

Update:

I updated below in my web.config:

<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>

It changes the output to:

Log showing me below issues:

CodePudding user response：

Error: The server encountered an error processing the request. See server logs for more details

This issue comes into picture whenever there is any issue at WCF service. So see more details about the issue, you need to includeexceptiondetailInfaults attribute to true in servicedebug tag.

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

Either you can also add class attribute to the service class.

For this problem, first check what version of this dll you have in your output directory.Then

• clean your solution
• delete all obj and bin directories
• uninstall this package from the whole solution
• ensure to delete this file in GAC: &userprofile%.nuget\packages\microsoft.data.services - make sure to delete whole directory
• now you can install from NuGet the required version
