Creating Module

Hi,
I'm a newbie with Sitefinity.
Now I'm trying to clone the Product Sample with Sitefinity 4.
I've got this Exception when I drag the widget into a page :
[TargetInvocationException: Property accessor 'ControlDefinition' on object 'ProductCatalogSample.Web.UI.Public.ProductDetailsView' threw the following exception:'Object does not match target type.']
What's wrong here ?
Thank You
Toky

Hello Toky,

Can you give me the stack trace so I can see where the error is occurring.  Also can you tell me how did you bind your control. If you include the source of your control so we can have a look at it locally would be nice.

I juste copy the sample project Products, then, I've referenced the ProductCatalogSample.dll
Is there any tutorial or a sample Helloworld-like project I should read ?

Thanks again,
Toky

Hello Toky,

The problem may be coming from the registration of the control into the system. Please consider reviewing the following article which is related to your module.
