After I installed SP4 I've been receiving the following error when trying to use the SDK:

The designer could not be shown for this file because none of the classes within it can be designed. The designer inspected the following classes in the file: FirstFormForm --- The base class 'Interprise.Presentation.Base.BaseForm' could not be loaded. Ensure the assembly has been referenced and that all projects have been built. Hide

at System.ComponentModel.Design.Serialization.CodeDomDesignerLoader.EnsureDocument(IDesignerSerializationManager manager) at System.ComponentModel.Design.Serialization.CodeDomDesignerLoader.PerformLoad(IDesignerSerializationManager manager) at Microsoft.VisualStudio.Design.Serialization.CodeDom.VSCodeDomDesignerLoader.PerformLoad(IDesignerSerializationManager serializationManager) at System.ComponentModel.Design.Serialization.BasicDesignerLoader.BeginLoad(IDesignerLoaderHost host)

Ramil,

Thanks for the update - I'll look for some sort of notice as to the availability of an updated SDK and may, in the mean time, 'downgrade' my local installation to SP3ΐ].

I'll write this off to inexperience but it might be useful to include something in the release notes that are distributed along with a release that warns about compatibility issues.
