I just wanted to inform you that when I followed the upgrade instructions to go from RC2 to RC3 I ran into a couple of issues.

1) Initially there were a number of build errors after copying the new files over. This was caused by the fact that certain library files were only in the Website/bin folder, but they needed to be put in the top-level Lib folder. The affected files were:

• CommerceBuilder.BackOfCanada.dll
  
• CommerceBuilder.dll
  
• CommerceBuilder.ECB.dll
  
• CommerceBuilder.Licensing.dll
  
• CommerceBuilder.Web.dll

The reason they need to be in the Lib folder is that when you build the site, the bin folder files get cleaned out and rebuilt and/or copied from the Lib folder, so without copying the new DLLs to the Lib folder they were just being overwritten by the older RC2 versions.

2) Once I was able to get the build errors resolved, there were 2 runtime errors caused by missing fields in the ac_Widgets table (this is an upgraded database from AC Gold > AC9 RC1 > AC9 RC2 > AC9 RC3). The missing fields were 'CreatedDate' and 'LastModifiedDate'. I manually added them to the ac_Widgets table and the site loaded properly.
