Inside a WinForms project, I derived a class from [`TypeConverter`](http://msdn.microsoft.com/en-us/library/system.componentmodel.typeconverter) in order to provide a custom type editor for an item in the property grid.

Unfortunately, my override of [`GetStandardValuesExclusive`](http://msdn.microsoft.com/en-us/library/b825831z(v=vs.110).aspx) never got called, while other overrides got called correctly.

[The solution](https://social.msdn.microsoft.com/Forums/en-US/ed391fd5-5b4f-47d6-ba8a-b25df719b1b0/getstandardvaluesexclusive-doesnt-seem-to-work) was to not derive my own class from `TypeConverter` but instead from the [`StringConverter`](http://msdn.microsoft.com/en-us/library/system.componentmodel.stringconverter) class.

After this change, my override of `GetStandardValuesExclusive` was called correctly.
