efcore: PMC Tools: Couldn't load assembly 'System.ComponentModel.Annotations'

Running PMC commands with the 2.1 nightlies has a binding redirect error:

Forcing a lower System.ComponentModel.Annotations and ignoring the nuget warnings makes it work.

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

Actually I eventually worked through this after spending a couple of hours on Google and StackOverflow.

I had to add the following to my web.config:

<dependentAssembly>
        <assemblyIdentity name="System.ComponentModel.Annotations" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-4.2.0.0" newVersion="4.2.1.0" />
      </dependentAssembly>

The key was figuring out the correct version number for the newVersion attribute.

I am having this issue and none of the suggested workarounds work for me. I am dead in the water. Everything was working fine for me until I stupidly decided to update nuget packages. I feel like I am back in DLL Hell.
