Hi Guys,

The contour developer docs haven't been updated since Per first wrote them in 2010.

http://umbraco.com/pro-downloads/contour/ContourDeveloperDocs.pdf

We wrote some extensions for contour 1.0.9.1 back when we first bought it. We're now upgrading to umbraco 6 and contour 3.0.7 and are having issues with a provider exception relating to one of our extensions:

[ProviderException: No provider with id 'cf98c85b-3105-467e-aeb4-bbb443442cd7' found]

   Umbraco.Forms.Core.Common.ProviderCollection`1.GetProvider(Guid id) +213

 public class TextfieldWithPreValue : Textfield

 {

  public TextfieldWithPreValue()

  {

   Id = new Guid("CF98C85B-3105-467E-AEB4-BBB443442CD7");

   Name = "Textfield with prevalue";

   Description = "Renders a html input fieldKey with a default value";

  }

is there anything we need to do differently to ensure our extensions are registered post our umbraco and contour upgrades?

Cheers,

Tom
