Upgrading dependent DLL without recompiling the whole application

问题

We have windows service application which is using Aspose.Words.NET version 11.10.0 Now we have recently upgraded the Aspose.Words dll version latest 13.7.0

Since we have already deployed our windows service applications in multiple clients, we tried replacing the old Aspose.Words dll with latest its latest version. But when we restart the existing windows application it doesn't work with the replaced latest Aspose.Words dll.

We have resolved it by recompiling the whole windows application referencing the latest version of Aspose.Words dll. Are we required to recompile and redeploy our whole windows service application every time we upgrade the Aspose.Words dll?

Check this answer on SO too.

You need to update the config files of the desktop/web clients as follows.

<configuration>
  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <publisherPolicy apply="no" />
        <assemblyIdentity name="Aspose.Words"  publicKeyToken="716fcc553a201e56" />
        <bindingRedirect oldVersion="11.0.0.0-13.6.0.0"
                         newVersion="13.7.0.0"/>
      </dependentAssembly>
    </assemblyBinding>
  </runtime>
</configuration>

Please also note that there might be breaking changes in API which might lead to other errors. For example a method or property which existed in 11.0 is deleted in 13.7. The exception will be thrown when the client application calls the specific method/property. So, you must verify in development environment that the new version will not break your application. If it works, then you can just replace the old DLL with new version.

The config file is loaded at runtime, so you can update the config files where your applications are deployed.
