    What is intermediate language in .NET ?

    .net supports CLS i. e. Common language type. its a microsoft’s feature to bring all languages near one roof.
    When You compile .net code it doesn't converted into binary language, it converted into IL (Intermediate Language) also known as MSIL. 
    And from IL to binary language converted at run time, CLR manages this process. At the runtime also it not converts whole project at time to binary, only converts that part which is going to execute, this the performance of project increases. This IL can use any language which is
    member of that .net studio. The assemblies (ExE, DLL) are also in IL form. So u can use any EXE or DLL created in vb.net in c#.net also.[which converts native code into byte code i.e machine understandable code.]
    Disadvantages of vb ?
    Following are the disadvantage of VB :
    1. VB is not object oriented.
    2. VB DLL does not support side-by-side execution
    3. Deployment is time consuming as all the components must 
    be registered in the Windows registry.
    [.The VB support OOP concepts, but not support fully.
    2.VB does not support exception handling.
    3.No multithreading mechanism.]
    Advantage of vb.net over vb ? 
    1,supports Threading
    2,powerful Exception handling
    mechanism
    3,having support for the
    console based applications
    4,More than one version of
    dll is supported
    [1. VB is object based while Vb.net is Object oriented
    2. VB.net using OO functionality like inheritenc a, 
    Excepetional handling, etc
    3.VB .net is strong type casting which VB lack
    4.VB.net supports multi threading....]

    Difference between VB dll and assemblies in .NET ?

    Assemblies can contain DLL and EXE both. Different versions of one DLL can be handled by assemblies. They overcome the DLL Hell problem. 
    Assemblies Contain Manifest and Meta Data files. These are the separate files that describes the Assembly and its attributes. VB DLL is inprocess.

    what are the types of threading models in VB.net ?

    There are lot of threading model available, but we focus on Threading models that are common to win32based environments singleThreaded:There is only one thread with in the process,and it is doing all the work for the process.The process must wait for the current execution of the thread to complete before it can perform another action.
    Apartment Threading (Single Threaded Apartment) Apartment threaded means there are multiple threads within the application. 
    In single threaded apartment (STA) each thread is isolated in a separate apartment underneath the process. The process can have any number of apartments that share data through a proxy. The application defines when and for how long the thread in each apartment should execute. All requests are serialized through the Windows message queue such that only a single apartment is accessed at a time and thus only a single thread will be executing at any one time Free Threading (Multi Threaded Apartment) Free threaded applications were limited to programming languages such as C++ until the release of Microsoft .NET. The free threaded/Multi Threaded Apartment (MTA) model has a single apartment created underneath the process rather than multiple apartments. This single apartment holds multiple threads rather than just a single thread. No message queue is required because all of the threads are a part of the same apartment and can share data without a proxy. The developer must provide thread synchronization as part of the code to ensure that threads do not simultaneously access the same resources.

    user itself and store in a custom library
