Question

When I view the root of my WCF Data Services service (http://localhost/MyService.svc/) in a browser I see this:

<?xml version="1.0" encoding="utf-8" standalone="yes" ?> 
<service xml:base="http://localhost/MyService.svc/" xmlns:atom="http://www.w3.org/2005/Atom" xmlns:app="http://www.w3.org/2007/app" xmlns="http://www.w3.org/2007/app">
<workspace>
<atom:title>Default</atom:title> 
</workspace>
</service>

I would expect to see a list of collections.

When I go to the $metadata URL I see this:

<?xml version="1.0" encoding="iso-8859-1" standalone="yes"?>
<edmx:Edmx Version="1.0" xmlns:edmx="http://schemas.microsoft.com/ado/2007/06/edmx">
      <edmx:DataServices xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata" m:DataServiceVersion="1.0">
        <Schema Namespace="MyApp" xmlns:d="http://schemas.microsoft.com/ado/2007/08/dataservices" xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata" xmlns="http://schemas.microsoft.com/ado/2007/05/edm">
          <ComplexType Name="Package">
            <Property Name="Id" Type="Edm.String" Nullable="true" />
          </ComplexType>
        </Schema>
        <Schema Namespace="MyApp" xmlns:d="http://schemas.microsoft.com/ado/2007/08/dataservices" xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata" xmlns="http://schemas.microsoft.com/ado/2007/05/edm">
          <EntityContainer Name="PackageService" m:IsDefaultEntityContainer="true">
            <FunctionImport Name="GetQueryablePackages" ReturnType="Collection(MyApp.Package)" m:HttpMethod="GET" />
          </EntityContainer>
        </Schema>
      </edmx:DataServices>
    </edmx:Edmx>

Why might my GetQueryablePackages collection not be appearing?

I’m using these access settings:

config.SetEntitySetAccessRule("*", EntitySetRights.AllRead);
config.SetServiceOperationAccessRule("*", ServiceOperationRights.All);

Service operations (the function import in the EDM) is not exposed in the service document. Only entity sets are exposed there.
If you want your data to be exposed in the service document make an entity set out of it. Depending on the provider model this differs. Typically it means exposing a property of type IQueryable on your context class. Note that T has to be an entity type (must have a key).
