The idea of business users being happy with re-hosted workflow designer tools should fail. For the time being it seems that intellisence and code highlightning for VB expressions are not available for re-hosted scenarios. This feature is available only for
Visual Studio 2010. I don't think companies will invest time, efforts and money inventing VB intellisense from the scratch, as well as trying to provide own syntax features, language bindings, etc. As for me the entire re-hosting idea is absolutely worthless
without this key feature. I would believe a C# gurus entering expressions without code completion, but will never belive business users typing VB in a plain textbox.
