Answer: This is a very general .NET interview question.
Normally properly planned companies have a checklist of what kind of naming convention to follow. In .NET interview its very difficult to speak about the whole checklist as we have limited time.
The expectation of the interviewer is that you should speak about pascal,camel and hungarian naming conventions and where did you use what.So below goes a short answer.
Our organization had a naming convention document which was supposed to be followed by all projects in the organization. As per the document we where using three types of naming conventions across the project :- Pascal , Camel and Hungarian.
All class names , function names , method names , namespace names where using pascal convention. i.e the first letter capital with every first word capital.ex CustomerCode
All variables , input/output variable , local variables , class level variable , global variables where using Camel notation. i.e. the first letter small and then the first letter of the subsequent words capital.ex count , customerData
For the UI obejct we where using hungarian notation. In this the prefix defines the datatypes i.e. txtCode , cmbCountries.
For database we used Hungarian notation where the prefix defines the data base object types. i.e. tblCustomer , uspSelectCustomer,fngetValue,trgInsert.
