Automapper and System.ValueTuple dependency/versioning problem

I have just added Automapper to my asp.net application (.net Framework 4.7), to see hopefully being able to replace some of the tedious manual mapping I always need to do.

I am now having a lot of problems with System.ValueTuple versions. I Notice I have a nuget package for System.ValueTuple v4.5.0. If I look into my solutions packages\System.ValueTuple.4.5.0\lib\net47\System.ValueTuple.dll I see this as version 4.6.26515.06. If I look into one of the projects I have this nuget package (the one that I added Automapper to), However, when I look in my bin folder after a build I have version 4.6.25514.4, ie and older version to what the nuget package has

When I build the app on the build machine picks up 4.6011.3. Yet another version!!!

I cannot uninstall the nuget package as it says that Automapper has a dependency on it.

When a user ran the application, they go the yellow screen of death, with

  Could not load file or assembly 'System.ValueTuple, Version=4.0.3.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

Does anyone know how to sort out this System.ValueTuple, and know why I seem to be getting random versions of it all over the place?

Thanks in advance!

[EDIT1]

Following @Lucian suggestion, I ran the Fusion tool on both my dev machine, and the other machine where it does not work.

I noticed, on my machine the ValueTuple DLL being found in my bin claimed to be version 4.0.2.0, and not what the file version was.

So I added...

 <dependentAssembly>
    <assemblyIdentity name="System.ValueTuple" publicKeyToken="cc7b13ffcd2ddd51" culture="neutral" />
    <bindingRedirect oldVersion="4.0.3.0" newVersion="4.0.2.0" />
   </dependentAssembly>

Previously, on my dev machine if I added any of these bindingRedirect I would also get the error, but now, with the above it worked.

However, it did not on the other production (internal test) machine. From that machine I have the following output (once I finally got Fusion to work) ...

I can see the line Redirect found in application configuration file: 4.0.3.0 redirected to 4.0.2.0. which it gets from the web.config, and 4.0.2.0 is what should be in the bin folder. This is also the version that shows up in Dotpeek..

For some reason, it then seems to try and get this DLL from C:/Windows/Microsoft.NET/Framework64/v4.0.30319/Temporary ASP.NET Files/MyApp, and it seems to end up with Assembly Name is: System.ValueTuple, Version=4.0.3.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51 and then it fails reports..

WRN: Comparing the assembly name resulted in the mismatch: Build Number
ERR: The assembly reference did not match the assembly definition found.

If I remove this bindingRedirect, it then reports looking for version 0.0.0.0. I have no idea what is going on here. The version we are trying to remap to, i.e. 4.0.2.0, is in the bin folder!

I also deleted the folder C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Temporary ASP.NET Files\MyApp, but this made no difference.

Any other ideas would be greatly appreciated.
