Dynamic LINQ API with .NET Framework 4

Is Dynamic LINQ API (released with the CSharpSamples), still the way to go, or is there a different / alter开发者_如何转开发native approach with .NET 4 (and EF 4)?

See my post here please for some generic options: Parsing a string C# LINQ expression.

Also EF 4 does have some built in string query parsing functionality added in...but it's completely specific to EF itself. See here for example: http://msdn.microsoft.com/en-us/library/bb338811.aspx
