Let me show you what is assembly with the help of picture . As we know one solution can have multiple projects, Whenever we compile  our application a assembly(.dll) is created inside  the bin folder . It means public member of one application can be accessed by another application of solution. You can consider one project as a signal assembly for your basic understanding. It means public member of one project can be accessible by another project by adding reference of project.
