I currently having an application running on a server and it is being host on IIS. The application is also connected to a dll file. I recently added a new method to call some methods from the dll file. But when I run the new method on the application, it returns a response of 200 without any response on the body.

I have tested other methods that are making calls to the dll file and they run perfectly fine. I have also checked the parameters on the method that I am making to the dll file. I have also reconfigured the IIS with my application.

But when I check the SQL profiler of the database I am connecting the application to, I got these:

• The new method is being executed by an ApplicationName of Core. Net SqlClient Data Provider
• The old methods (which are also making call to the dll) is being executed by the IIS

So what I would like to ask is that could this be a reason for the result of having a 200 response with no body, since this is the first time I am seeing that two same methods using the same connection strings but only one is being connected to the SQL?
If so, which would be a good solution to handle this?

Thank you very much, I have been researching about this for weeks and haven’t been able to figure it out.
I have my application running in .Net Core 6 and the dll is in Delphi
