WinForm Application UI Hangs during Long-Running Operation

Question

I have a windows forms application on which I need to use a for loop having a large number of Remote Calls around 2000 - 3000 calls,

and while executing the for loop

Answer 1

    private voidForm_Load(object sender, EventArgs e)
    {
        MethodInvoker mk = delegate
        {
            //your job
        };
        mk.BeginInvoke(callbackfunction, null);
    }

    private void callbackfunction(IAsyncResult res)
    {
        // it will be called when your job finishes.
    }

use MethodInvoker is the easiest way.
