Does my ASP.NET application stop executing if I overwrite the DLLs?

Question

Assume that my ASP.NET application is making 4 separate database calls. If after the 2nd call, I overwrite the DLLs in BIN folder, does it stop the application from continui

Answer 1

The assemblies are loaded into the app domain, and app domain watches the directory, if you replace the assemblies it will recycle the app and reload the assemblies. So yes your 3rd/4th calls would fail.
