Quotations evaluation problem
f#

hi
i am trying to evaluate Quotations but compile error occure I have downloaded powerpack and add needed references but get compilation error

Error 1 The namespace 'QuotationEvaluator' is not defined C:\Users\Hani\Documents\Visual Studio 2008\Projects\ConsoleApplication1\ConsoleApplication1\Program.fs 6 28 ConsoleApplication1

Error 2 The field, constructor or member 'Eval' is not defined C:\Users\Hani\Documents\Visual Studio 2008\Projects\ConsoleApplication1\ConsoleApplication1\Program.fs 11 3 ConsoleApplication1

the code is

open Microsoft.FSharp.Quotations
open Microsoft.FSharp.Quotations.Patterns
open Microsoft.FSharp.Quotations.DerivedPatterns
open Microsoft.FSharp.Linq.QuotationEvaluator

let a = <@3+4@>
a.Eval();;

thank you in advance

.

Probably you should add reference to FSharp.PowerPack.Linq.dll. Also I opened "Microsoft.FSharp.Linq.QuotationEvaluation" namespace. The code below is working for me:

#r "FSharp.PowerPack.dll"

#r "FSharp.PowerPack.Linq.dll"

open Microsoft.FSharp.Quotations

open Microsoft.FSharp.Quotations.Patterns

open Microsoft.FSharp.Quotations.DerivedPatterns

open Microsoft.FSharp.Linq

open Microsoft.FSharp.Linq.QuotationEvaluation

let a = <@3+4@>

a.Eval();;
