I want to create a new base-form which inherits from the standard Windows form. I want to add some properties to the new form. For example: a standard form has a property tag and I want my form to have multiple tag properties like tag1, tag2 etc.
The new class should be saved in a dll and new forms have to be instantiated from my new class.
Thanks in advance.

New form based on standard form

just change the inherits from System.Windows.Forms.Form to YourNamespace.YourFormTemplate, and it should work fine.
