Hi,

I have two custom rules as below:

1. Ensure all private field use underscore as prefix.
2. Ensure UI control use corresponding prefix, for example txt for textbox, cbo for combobox, chk for checkbox and etc.
   

I was having test as below with "Exclude *.designer files" OFF:

1. I dropped some UI controls on form and run CIR to analysis.
2. CIR complaint my UI controls declaration in *.designer file not using underscore as prefix (since UI controls are declared as private by default)

I don't really want my UI control name to use under prefix. Instead, I want them to follow prefix as mentioned in 2nd custom rule.

Shall we have "Exclude *.designer files" OFF" tight to rule level instead of only global?
As you can see the above scenario, I want rule 1 to apply to all code file except *.designer.

On the other hand, I want rule 2 to apply to *.designer file as well.

 Please advice. Thank you

There are currently few ways of doing this (although neither is perfect):

• Create multiple profiles and switch between them
  
  
• Add [System.Diagnostics.CodeAnalysis.SuppressMessage("SubMain.CodeItRight.Rules.Naming", "NA00016:UseOrAvoidCertainPrefixes")] attribute in fron of each of the control declarations in the form - this will tell CIR to ignore the rule that that forces the underscores to controls.
  
  
• Custom Rule. I'm attaching excample that will add underscores to private fields that are not controls and "txt" TextBox controls. The example is just plain hardcoded but should give you idea.
