In my last
post, I described a rather tedious and error prone method for configuring One To One client certificate mappings in IIS 7.5, so with a little bit of
help I created a small WPF application that should ensure the smooth configuration of one to one client certificate mappings.
There is no validation as this is simply a developer tool and I'm too lazy to add it, you can have a look at this
post for an example of textbox validation in WPF.
