Add DLL in ASP NET Web Service

Today I added DLL in my ASP NET Web Service.I found two w开发者_如何转开发ays to add DLL.

First one is - Right click on project << Add Reference << Browser << Select the DLL.

Second one is - Right click on bin folder << Add Existing Item << Select the DLL.

Both are working fine.So now my question is "Is there any difference between both ways?"

If yes then please do reply.

Thanks in advance.

Regards, Mohit Kumar.

you forgot the 3rd one...

Drag the dll directly into your BIN fodler :)

They all the same, though I suggest the "correct way", add your Libraries through Add Reference Menu
