Setting default in configurable add-in

Hi there,

How do you set defaults for properties of a configurable add-in? I tried setting them in the constructor of an AddressValidatorProvider like this:

public MyAddressValidatorProvider()
{
ApiUrl = "http://my.url";
}

But then the user defined values are no longer applied and I see my defaults again when editing the add-in. Is there a way to detect if the add-in is configured for the first time? Or can I handle this some other way?

Hi Imar,

Due to the way property values are set on ConfigurableAddIn objects, you need to specify default values on the property instead of in your constructor.

Great, thanks, that did the trick. In my case, I had to convert my automatic properties to properties with a backing field, and then assign a default value to the private field as I am using C# pre 6.0.

Thanks!

That's one of the few places where VB was actually ahead of C#. Definitely a great addition to C# 6.0 :)

Glad you got it working :)
