.net 6 support

[OPSnake]

Hi,

I have an exception with .net6. The FindEntityType method is not an extension method in .net 6.
Message: 
System.MissingMethodException : Method not found: 'Microsoft.EntityFrameworkCore.Metadata.IEntityType Microsoft.EntityFrameworkCore.ModelExtensions.FindEntityType(Microsoft.EntityFrameworkCore.Metadata.IModel, System.Type)'.

Arborescence des appels de procédure: 
EFHelper.GetKeyProperty(DbContext context, Type t)
MappingHelper.GetEntityMapping[T](DbContext context, Type queryClass, Dictionary2 allowedPropertyMapping) MemoryJoiner.FromLocalList[T](DbContext context, IList1 data, Type queryClass, ValuesInjectionMethod method)
MemoryJoiner.FromLocalList[T](DbContext context, IList1 data, Type queryClass) MemoryJoiner.FromLocalList[T](DbContext context, IList1 data)

Thanks

Hi @OPSnake , .Net 6 should be supported in the latest version.
