I have a project .Net Framework 4.6.1 WPFthat references several assemblies .Net Standard 2.0. Each of these assemblies has one or two own dependencies deduced from NuGet. When inside Visual Studio everything works and works fine. However, when I first tried to publish the application and run it (on the same computer), I received this nasty exception:
Failed to load file or assembly "System.Runtime, Version = 4.1.2.0, Culture = neutral, PublicKeyToken = b03f5f7f11d50a3a" or one of its dependencies. The system cannot find the specified file.
After several days of hair pulling, I finally found that by adding the following link redirects to my project, App.config solved the problem
<dependentAssembly>
<assemblyIdentity name="System.Runtime" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-4.1.2.0" newVersion="4.1.2.0" />
</dependentAssembly>
At least the problem has been ported to System.ObjectModel. Then, after I added the binding redirect for it, I got an error message for System.Collectionsetc ... soon my App.config looked like this:

I recently added a ServiceStack.Client.CoreNuGet package to one of my assemblers .Net Standardand added code that calls calls to a web service. Again, everything worked fine in Visual Studio, but when I went to publish the application and then started it, I started to see these errors again whenever the application tries to call my web service. I started adding binding redirects until I came across an assembly that seems to want two different versions:
"System.IO.Compression, Version = 4.2.0.0, Culture = neutral, PublicKeyToken = b77a5c561934e089" .
:
"System.IO.Compression, Version = 4.1.1.0, Culture = neutral, PublicKeyToken = b77a5c561934e089" .
