  Hi 
  I get the above error and I don't know what to do. I have went through a lot of pages, but nothing seams to get rid of the error. The error doesn't show up on compile time. I have 10-15 times reinstalled the nuget in both projects. 
  
  It's first after I made a new project (Businesslayer) the error came. 
  
  The error come here

  <th>
              @Html.DisplayNameFor(model => model.Name)
          </th>

  I have checked the System.ComponentModel version and also System.ComponentModel.Annotations and both is the same what I installed in the Nuget manager.
  
  The BusinessLayer project look like this

  <Project Sdk="Microsoft.NET.Sdk">
  
    <PropertyGroup>
      <TargetFramework>netstandard2.0</TargetFramework>
    </PropertyGroup>
  
    <ItemGroup>
      <PackageReference Include="System.ComponentModel" Version="4.3.0" />
      <PackageReference Include="System.ComponentModel.Annotations" Version="5.0.0" />
      <PackageReference Include="System.Data.SqlClient" Version="4.8.2" />
    </ItemGroup>
  
    <ItemGroup>
      <Reference Include="System.Configuration">
        <HintPath>..\..\..\..\..\..\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.7.2\System.Configuration.dll</HintPath>
      </Reference>
    </ItemGroup>
  </Project>

  I hope some of you can help me. I do not know what to do :-)
  
  Best regards

  I don't know if that helps you telling me what I have to do.
  
  I remove the System.ComponentModel.Annotations from my project in both projects. Then I go into Nuget Manager and install the latest stabel 5.0.0.
  
  Then when look in my object browser I can see 2 System.ComponentModel.Annotations first 4.2.0.0 and then 4.2.1.0.
  
  I have tried to remove the bin folder - then I right click on the System.ComponentModel.Annotations.dll file an the fileversion sais 4.6.26515.6
  
  I'm confused

  Hi SimsenVejle,

  You can try bindingRedirect to redirect one assembly version to another.

  <bindingRedirect oldVersion="0.0.0.0-5.0.0.0" newVersion="4.2.0.0" />

  You can click this link to see a more detailed explanation.
