Initially we have framework version 3.1 and Entity framework autohistory 2.1
Then we have upgraded the version framework version 6.0 and Entity framework autohistory 5.0.8

After upgraded framework version autohistory not working and it's throw an error as below
"Method not found: 'System.Type Microsoft.EntityFrameworkCore.Metadata.ITypeBase.get_ClrType()'"

Please confirm which autohistory version will work for framework 6.0

@SUBRAMANI Praveena ,Welcome to Microsoft Q&A.
Microsoft.EntityFrameworkCore.AutoHistory -Version 5.0.8 is compatible with target structure .Net5.0 .
I suggest you use Microsoft.EntityFrameworkCore.AutoHistory -Version 6.0.0. when the structure is .Net6.0 . You can check this link.
It is also possible that you are using several different versions of EF Core in a mix. You can provide your csproj to check if all EF-related packages are the same version.
