ValueConverter<TModel,TProvider>(Expression<Func<TModel,TProvider>>, Expression<Func<TProvider,TModel>>, Boolean)
- Source:
- ValueConverter`.cs
Initializes a new instance of the ValueConverter<TModel,TProvider> class, allowing conversion of nulls.
Warning: this is currently an internal API since converting nulls to and from the database can lead to broken queries and other issues. See GitHub issue #26230 for more information and examples.
