I'm working on a massive project where manual renaming cannot be done.
Problem is that ADO.NET Visual Studio Default tool was renaming TablieFieldName:Name to TableFieldName_Name and your tool renames it to: TableFieldNameName.
Real-life example:

Again, manual renaming cannot be done. I guess your tool don't have this functionality to change this behavior, but are you thinking to implement it in near future?
