Asp.net c# Class 库 dll 正确版本未正确加载

Question

I created a class library and called id sharepointClassSample library. It has a reference to Microsoft.Sharepoint.Client.dll version 16.1.0.0 along other ones.

I compiled the library and moved the resulted files to a folder called myLibrary

I created a project and referenced the sharepointClassSample.dll within the myLibrary folder. Compiled the project and all the dlls needed by the sharepointClassSample.dll library were copied to my project bin/debug folder.

But the Microsoft.Sharepoint.Client.dll copied on my folder is 15.0.0.0

Is there a way or setting within the Class library project that allow to specify the right dlls versions to be copied when the library is referenced?

Answer 1

1. You should be able to use bindingRedirect to use the specified version.

For example:

<configuration>
    <runtime>
       <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
          <dependentAssembly>
             <assemblyIdentity name="myAssembly"
                               publicKeyToken="32ab4ba45e0a69a1"
                               culture="neutral" />
             <bindingRedirect oldVersion="1.0.0.0"
                              newVersion="2.0.0.0"/>
          </dependentAssembly>
       </assemblyBinding>
    </runtime>
</configuration>

In addition, redirect rules can specify to redirect within a certain version range

2. You can also use the NuGet package manager: Add the required DLL using the NuGet package manager in the class library project and specify the required version.

3. Manually add DLL: Copy the DLL file to the class library project and add a reference in the project.

When referencing a library, setting the build action to copy to output directory on the reference properties does not result in a version change.
