We are w开发者_JAVA百科orking 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.

Are you using Windows7 OS?

I suggest you to follow the steps below.

1. Remove reference of WPFVisifire.Charts.dll and WPFToolkit.dll (if used) from your project.
2. Clean your project.
3. Close the application.
4. Right click no WPFVisifire.Charts.dll and WPFToolkit.dll(if used) then click on properties.
5. Go to General Tab.
6. Click on Unblock button.
7. Now open your project in Visual Studio.
8. Add new reference to unblocked WPFVisifire.Charts.dll and WPFToolkit.dll(if used).
9. Compile your project and run.
