Properties

ConstructorExpression	The expression representing construction of this object. (Inherited from ValueConverter<TModel,TProvider>)
ConvertFromProvider	Gets the function to convert objects when reading data from the store, setup to handle nulls, boxing, and non-exact matches of simple types. (Inherited from ValueConverter<TModel,TProvider>)
ConvertFromProviderExpression	Gets the expression to convert objects when reading data from the store, exactly as supplied and may not handle nulls, boxing, and non-exact matches of simple types. (Inherited from ValueConverter<TModel,TProvider>)
ConvertFromProviderTyped	Gets the function to convert objects when reading data from the store. (Inherited from ValueConverter<TModel,TProvider>)
