Free threadNow, when developers create applications in Visual Basic, the code they write is synchronized. This means that each line of code is executed before the next line of code. Scalability is critical when developing Web applications. Developers must use parallel processing as a possible tool. With free threads, developers can generate a thread to complete some long-running tasks, exe
