Fixes #19383 Fixes #17123 > No suitable constructor was found for entity type 'BlogNone'. The following constructors had parameters that could not be bound to properties of the entity type: cannot bind 'did' in 'BlogNone(string title, int did)'; cannot bind 'notTitle' in 'BlogNone(string notTitle, Guid? shadow, int id)'; cannot bind 'dummy' in 'BlogNone(string title, Guid? shadow, bool dummy, int id)'; cannot bind 'dummy', 'description' in 'BlogNone(string title, Guid? shadow, bool dummy, int id, string description)'. Note that only mapped properties can be bound to constructor parameters. Navigations to related entities, including references to owned types, cannot be bound. Fixes #26341 > The 'DateOnly' property 'Blog.PostedOn' could not be mapped because the database provider does not support this type. Consider converting the property value to a type supported by the database using a value converter. See https://aka.ms/efcore-docs-value-converters for more information. Alternately, exclude the property from the model using the '[NotMapped]' attribute or by using 'EntityTypeBuilder.Ignore' in 'OnModelCreating'. Or if the store type is specified: > The 'DateOnly' property 'Blog.PostedOn' could not be mapped to the database type 'datetime2' because the database provider does not support mapping 'DateOnly' properties to 'datetime2' columns. Consider mapping to a different database type or converting the property value to a type supported by the database using a value converter. See https://aka.ms/efcore-docs-value-converters for more information. Alternately, exclude the property from the model using the '[NotMapped]' attribute or by using 'EntityTypeBuilder.Ignore' in 'OnModelCreating'. Fixes #21954 > Cannot save instance of 'Skinner' because it is an owned entity without any reference to its owner. Owned entities can only be saved as part of an aggregate also including the owner entity.
