Syntax

'Declaration
Public NotInheritable Class EntitySet(Of TEntity As Entity) _
    Inherits EntitySet _
    Implements IEnumerable(Of TEntity), IEnumerable, ICollectionViewFactory

'Usage
Dim instance As EntitySet(Of TEntity)

public sealed class EntitySet<TEntity> : EntitySet, 
    IEnumerable<TEntity>, IEnumerable, ICollectionViewFactory
where TEntity : Entity

generic<typename TEntity>
where TEntity : Entity
public ref class EntitySet sealed : public EntitySet, 
    IEnumerable<TEntity>, IEnumerable, ICollectionViewFactory

[<SealedAttribute>]
type EntitySet<'TEntity when 'TEntity : Entity> =  
    class
        inherit EntitySet
        interface IEnumerable<'TEntity>
        interface IEnumerable
        interface ICollectionViewFactory
    end

JScript does not support generic types and methods.
