Definition for 'Select' not working in CSharpScript.EvaluateAsync

I am having problems getting this code to work. It seems that the CSharpScript.EvaluateAsync will not understand the Linq 'Select' command even though I think I am adding the proper references to the ScriptOptions. The goal here is to use the EvaluateAsync to run string based Linq queries. Thanks for your assistance in advance.

List<Dog> dogs = new List<Dog>();

dogs.Add(new Dog()
{ Name = "spike", Breed = "Poodle" });

dogs.Add(new Dog()
{ Name = "george", Breed = "Spaniel" });

dogs.Add(new Dog()
{ Name = "sammy", Breed = "Weimaraner" });


Console.WriteLine("Analyzing List");

// Func to return max string length of Breed Property in list of Dogs
int maxlen = dogs.Select(d => d.Breed.Trim().Length).OrderByDescending(d1 => d1).First();



// Recreated Func using Microsoft.CodeAnalysis.CSharp.Scripting.
var myLambda = "d => d.Select(d => d.Breed.Trim().Length).OrderByDescending(d1 => d1).First()";

Assembly[] assemblies = {
    typeof(Dog).Assembly,
    System.Reflection.Assembly.Load("System.Collections"),
    System.Reflection.Assembly.Load("System.Linq"),
    System.Reflection.Assembly.GetExecutingAssembly()
    
};

ScriptOptions options = ScriptOptions.Default.AddReferences(
             assemblies
            );

Func<List<Dog>, int> Dexprssn = await CSharpScript.EvaluateAsync<Func<List<Dog>, int>>(myLambda, options);
/*
   Error
        Microsoft.CodeAnalysis.Scripting.CompilationErrorException
        HResult=0x80131500
        Message=(1,8): error CS1061: 'Dog' does not contain a definition for 'Select' and no accessible

 */

Adding assemblies as references is one part of it but to add any 'using directives' then you should also use AddImports():

//..

ScriptOptions options = ScriptOptions.Default.AddReferences(assemblies);

options = options.AddImports("System.Linq");

//..
