Write a (good) code convention for c#

As a relative new trainee in my company, I've been asked to write a code convention since the project is 6 years old and nothing have been done.

Here's the points I came up with:

1. VARIABLE DECLARATION
   
   
   
   
   • Position
   
   
   • Initialization
   
   
   • Naming
   
   
   • Types
   
   
   
   


2. THE CONDITION BLOCK
   
   
   
   • If
   
   
   • If/Else/Else If
   
   
   
   


3. LOOPS
   
   
   
   
   • The For family
   
   
   • The ”standard” for loop
   
   
   • The ForEach loop
   
   
   • The ForEach with LINQ
   
   
   • The While and Do/While
   
   
   
   


4. THE CLASSES
   
   
   
   • Naming
   
   
   • Declaring members
   
   
   • Auto Property
   
   
   • Read-Only
   
   
   • Naming
   
   
   • Functions and Methods
   
   
   • Naming
   
   
   • Arguments
   
   
   
   


5. GOOD PRACTICES
   
   
   
   
   • && and ||
   
   
   • Boolean logic
   
   
   • New operator
   
   
   • Comments
   
   
   • Try/Catch
   
   
   
   

It's not necessary that I details the points, but does the structure/content seems relevant?
