Workaround of Record creation problem in Dynamics CRM 365 Online from ".NET Core 2.1"

-
If you want to make any calls from .NET Core 2.1 app to Dynamics CRM 365 online, you will face the following error:
System.TypeLoadException : 
'Could not load type 'System.ServiceModel.Description.MetadataConversionError' 
from assembly 'System.ServiceModel, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.'


It is incompatibility of metadata serialization.

Please have a look at my article from

good luck.
