  Hi Mahesh, I read ur article and it is very nicely explained...but i have a question to ask...it might be silly but still i m serious that i don't know the answer.. Ok my question is..suppose we add a Windows Media Player component in Visual Studio 2010 and we when we build our application it works fine, but when we copy just the exe file from release folder to some other folder, it gives error on runtime...u know what must be the problem? ....i m guessing that the problem are the dll files of windows media player component in release folder...the application works fine with all those files in the same folder..! Please reply ASAP..! Thanks Udit

  Hi, AllowAddition property has to be boolean since you set the property value to FALSE or TRUE. Is there any reason you kept it as String. If so, the property value setting to be in quotes right. Let me know if I am wrong.

    Is there a limit to the size of a class library dll, and is there a recommended max size?

  You may need to install the missing component.

    You can use it using the LoadLibrary method. Read more document on reflection and loading DLL dynamically. Search this site. I think there are some articles on it. Or search www.c-sharpcorner.com

    Yes this is a class library. To use it, just add reference to your application by RIGHT CLICK ON PROJECT -> SELECT ADD REFERENCE menu item -> Browse this DLL. An assembly is a generic name from a DLL or EXE in .NET.

    Hello! I read your article and dozen more. Is it possible to use the created dll without adding it to the references? (For example: register with regsrv32.exe and use..) Robert

  hi mahesh Iam a new member of this site. i need clarification for 2 of my doubts: 1. in our company, for any application we create in vb.net , we do it in a 3 tier architectural style ( we create 3 projects for presentation layer, business layer and datalayer) . And for each layer we add reference. My question : Is the above way we do, is called COM implementation in vb.net ? 2. Is the word 'COM' referred as 'COM' itself in .net terminology or by some other name ?

    1. For development, Project Reference is preferable than the assembly reference. However, assembly reference is also OK as long as your team is OK with it. 2. Yes COM is same. There is no seperate COM in .NET.
