When I tried to upgrade a WinForm project integrating Microsoft OWC from Sept CTP to RTM recently, I faced an error that some assemblies are missing, like the "MSDATASRC 8.0.. blah blah".
I'm pretty sure I clean all CTP products properly and then install the RTM of VS2005. Therefore, I guess there are something wrong in the registration of the OWC component. I uninstall the component and then manually install it. It works. The component is visible in my toolbox and I'm able to drag & drop the control on my WinForm:
Therefore, I listed out my un/re-install/register procedures and informed my colleagues. Ouch... No luck, all of the errors appear in his machine... I have no idea but later, he can compile the project successuflly in VS2005 RTM by clicking 1 button! The magic is... the "Clean" button when right-clicking the project name in Solution Explorer.
I can't search any useful information about the use of this option on MSDN site... What's the actual use of this mysterious Clean option?
