New features in the Entity Framework support!

Post by Devart » Thu 09 Aug 2012 11:44

Dear users,

We are glad to announce the new features that are available in the Entity Framework support in the latest version:
  • The config.QueryOptions.UseCSharpNullComparisonBehavior configuration option for checking for NULL when comparing a nullable property (column) or an expression with a variable (parameter) in LINQ to Entities is implemented (by default, false) (MySQL, Oracle, PostgreSQL, SQLite)
  • The bug with automatic setting of the ColumnTypeCasingConventionCompatibility configuration option to True when using EF Code-First 4.3 or higher and ObjectContext with XML mapping (the attributes of the EdmSchemaAttribute assembly level) simultaneously is fixed (MySQL, Oracle, PostgreSQL, SQLite)
  • The config.QueryOptions.CaseInsensitiveComparison option is implemented to manage the compare behaviour when using Linq to Entities comparison expression such as "a == b" (by default, false) (Oracle)
  • The behaviour is changed: Substring() in LINQ queries is now translated to DBMS_LOB.SUBSTR for LOBs (Oracle)
  • The bug with comparing char fields in the non-unicode mode is fixed (Oracle)
