nopCommerce version 4.20
Visual Studio 2019 and Server http://dev.callapg.com/

We're getting this error in dev:
"ReflectionTypeLoadException: Unable to load one or more of the requested types.
Could not load file or assembly 'SevenSpikes.Nop.Services, Version=4.2.658.31947, Culture=neutral, PublicKeyToken=null'. The system cannot find the file specified."

when I run locally, it turns out that version 4.2.658.31947 clashes with line 544 of the ApplicationPartManagerExtension

'pluginDescriptor.ReferencedAssembly.GetTypes()' threw an exception of type 'System.Reflection.ReflectionTypeLoadException'

The version of SevenSpikes.Nop.Services.dll is 4.2.650.31860?

How do I get the correct version of the core DLLs?
