Hello Guys, I have a project with Asp.Net Framwork MVC version 4.6. 

My project work very well for me but when I deployed it into IIS server by using docker cicd to auto deploy code to IIS server. many time before deploy always worked for me but today I deploy and get an exception: No parameterless constructor defined for this object.

Exception Details: System.MissingMethodException: No parameterless constructor defined for this object.

Source Error:
