HasScale(Nullable<Int32>, Boolean)	Configures the scale of the property.
HasSentinel(Object, Boolean)	Configures the value that will be used to determine if the property has been set or not. If the property is set to the sentinel value, then it is considered not set. By default, the sentinel value is the CLR default value for the type of the property.

When a property is configured as a concurrency token the value in the database will be checked when an instance of this entity type is updated or deleted during SaveChanges() to ensure it has not changed since the instance was retrieved from the database. If it has changed, an exception will be thrown and the changes will not be applied to the database.
IsRequired(Nullable<Boolean>, Boolean)	Configures whether this property must have a value assigned or null is a valid value. A property can only be configured as non-required if it is based on a CLR type that can be assigned null.
IsUnicode(Nullable<Boolean>, Boolean)	Configures whether the property as capable of persisting unicode characters.
SetElementType(Type, Boolean)	This is an internal API that supports the Entity Framework Core infrastructure and not subject to the same compatibility standards as public APIs. It may be changed or removed without notice in any release. You should only use it directly in your code with extreme caution and knowing that doing so can result in application failures when updating to a new Entity Framework Core release.
ValueGenerated(Nullable<ValueGenerated>, Boolean)	Sets a value indicating when a value for this property will be generated by the database. Even when the property is set to be generated by the database, EF may still attempt to save a specific value (rather than having one generated by the database) when the entity is added and a value is assigned, or the property is marked as modified for an existing entity. See GetBeforeSaveBehavior() and GetAfterSaveBehavior() for more information and examples.
