We released WebUI Studio.NET 2008 R1 last March, which contains all products included in WebUI Studio.NET 2007 R2, plus 2 new components (WebAqua and WebScheduler). Customers who have purchased WebUI Studio.NET 2007 R2 can obtain the latest build included in WebUI Studio.NET 2008 R1 using Update Manager or My Components in TDN2.
The following error will likely to occur after you apply the new build:
[MissingFieldException]: Field not found:’ISNet.WebUI.ProductInfo.Is2008Product’.
To fix this issue, simply update the WebUI.NET Framework to the latest build (build 559 or higher), which can be obtained from Update Manager or My Components in TDN2. Don’t forget to copy the new assemblies to your project’s bin folder. And last but not least, clear the .NET Temporary Files cache to ensure you have used the latest build version.
