Is managed DLL binary compatible?

This is in continuation of the error discussed in my earlier blog .

While working with this error I accidently clicked on my main application without rebuilding and it worked although I had done changes to my referenced DLL.

Does it mean compiled DLL are binary compatible?

Lets see how it works,

Below image show my code
 
  • Referenced DLL (you can see I’ve commented the overloaded API ) 

  • My test application code  

Now I build my exe and read the generated IL code in C# using reflector
Below are the images:

  • When overloaded API is commented 

  

  • When overloaded API is uncommented and my application is rebuilt. 

   

These images reveal that compiler intelligently creates the syntax (in IL) according to the best available function.

Pretty interesting stuff!!
