ADO.NET Entity Framework 4.1.10715.0

Provider interface allows better reasoning about primitive types Set of features that build on top of Entity Framework 4.0 Beta 1 (included in .NET Framework 4.0 Beta 1) Performance improvements · Much quicker object query execution · Simpler generated SQL · Faster view generation Easier disconnected operation · Public, serializable EntityKey property on EntityReference · ApplyPropertyChanges · Attach on EntityReference · Improvements to EntityKey serialization Extensibility and business logic enhancements · Partial methods in code generation for property changing and property changed events · Load with MergeOption · AssociationChanged Event Query improvements · Additional canonical functions for LINQ to Entities · Apply operator elimination (makes more operations work in SQL Server 2000 and other databases) · Compiled LINQ query · ToTraceString() method on ObjectQuery and EntityCommand to facilitate debugging Other · Connection management refinements · Provider interface allows better reasoning about primitive types Requirements: · NET Framework 4.0 Beta 1 (Required) · Visual Studio 2010 Beta 1 (Optional, for leveraging design time templates) What’s New in This Release: · Bug fix to remove the need to specify ‘Persist Security Info=True’ in the connection string when using SQL authentication. This change predominantly affects users connecting to SQL Azure. Introduction of new types to facilitate design-time tools for Code First: · DbContextInfo can be used to instantiate and interact with a derived context as well as determine information about the origin of the connection string etc.. · IDbContextFactory is used to let DbContextInfo know how to construct derived DbContext types that do not expose a default constructor. If your context does not expose a default constructor then an implementation if IDbContextFactory should be included in the same assembly as your derived context type.
