How to set the ValueConversion attribut for a IMultiValueConverter

Question

I changed my converter from IValueConverter to IMultiValueConverter : Previously I converted int to string :

[ValueConversion(typeof(int), typeof(string))]

But now I convert an int and a double to a string.

How should I specify my ValueConversion attribut now ? I have two input and one output now.

Answer 1

I dont think you can use ValueConversionAttribute with an implementation of IMultiValueConverter

I think ValueConversionAttribute is primarily used for design-time support and MultiBindings dont seem to make much sense in this context
