Porting VB6 Add-on to .NET Add-Ins

I am in process of converting an old VB6(ArcGIS 9.3) Add-on to .NET Add-Ins for ArcMap 10.6

the Add-on allows the user to Split or Merge road segments and adjusts their addresses accordingly.

The Old one contain:

1-  2 Forms:  Setup Form and the split Form.

2-  a Class Module that communicate between the forms and Error Handler Module.


Attaching  the class Module.

I have no idea on how to start this project,  I have no clear information of how to get the right solution

since I have snapping in the tool  and the way of the error handling.


My Question is Which approach should I follow,  Using Add-ins (is there any snapping limitation)  or use com.

for either way you advice:

1- what the steps I have to follow,  and how can I use the Error Handler.

2- what solution Template in VS 2017  should I use


Looking for any Help.   and  clsSplitroad code migration will be great help.


Thank you
