Use with Blend and creating Sample Data from Classes

Jun 19, 2012 at 8:24 PM

Hi,

I was wondering if anyone has experienced problems generating sample data using Expression Blend?

I am utilizing the WAF and want to design my Views in Blend, however, I get an error when try and create sample data from a ViewModel class.

The error is a popup window containing "Value cannot be null. Parameter name:key".  Not particularly helpful.

Any clues?

Thanks,

 

Andy
