Question

Exception:

Could not load file or assembly 'WPFVisifire.Charts, Version=4.1.0.0, Culture=neutral, PublicKeyToken=99d724542e4db593' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

We are working with our stock exchange charting application using Visifire. We have two app versions. Online Silverlight version and desktop WPF version. I already created Silverlight application and its working well. Same code I copied in WPF application but WPF chart application throws exception.

I’m very new to dot net development. Please help.
