Well after receiving Visual Studio 2008 yesterday. I proceeded to get my update done and see how the final product compared to the last Beta of the product I had used.
Prior to me receiving my copy of Visual Studio 2008 I had read Scott Guthrie's Blog post on "Steps to Uninstall VS 2008 Beta2 before installing the VS 2008 Final Release". This had given me a head start or preparing to do the upgrade.
Although even with this knowledge I did forget to uninstall one of the components from the Beta 2 build. I was impressed when the install caught this and let me know about it prior to allowing me to install the RTM version. I had forgotten to uninstall the MSDN Library.
After installing I ran visual studio and have not had any issues with the product so far as any bugs have been found, but I have ran across an issue with developing modules for DotNetNuke which I will be addressing in another blog post later today or tomorrow.
