Exe Creation for WinForms Application

As you have stated, you have references of dlls, your exe must have that dll present where your exe exists, if you want to install on target machine then consider creating a setup of that.

once you go throught your code and see anywhere are you getting any object which is not initlize before or you can put log files also to track that from where this issue is coming.

Hi. You are getting issue like, "Object reference not set to an instance" which means that when you are creating any kind of object at that time the object is null but after that when you are trying to use that object then it will show such error because that object contains null. So what you can do is put a breakpoint and check where you are getting the issues.If you get any issues then you need to resolve it. Thanks
