THe specified dll was not packed with the setup, of course it would work if you paste it in the bin directory same as in your application. You also have to pack that dll with the application when you intend to distribute it.
First, you can view the dll's in your project or even import new ones. Try this:
1) Press,
Alt + P + P : This displays the project property page.
2) Click on the
References tab : Here, you'll see all the dll's referenced in your project and you can add your
Basic.dll
To create the setup to include the basic.dll in your distribution files,
