When an Application is using your component(DLL),You Should Change the Name of the Existing Method/Property/Class. If you change, existing application may not work properly.

And it is not that every time when you Modify&Compile your component you should re-compile your application(Which is impossible in real-time scenario).

All that you will have to do is Set the Version Compatibility Option Available in the Project-Component of the Component(DLL) to Binary Compatibility.

Now if you re-compile your COMPONENT you need not re-compile existing application. Reason When You select Binary Compatibility option CLASSID & GUID are Preserved. It does't generate a new ones.
