Minor issue: when LLBLGen 1.0.2005.1 Final generates adapter scenario C# code for Visual Studio 2005, the "DatabaseSpecific" classes and app.config are all marked in the project file as having a custom tool of "LLBLGen Pro". This causes warnings during the build. (I'm using VS2005 RTM).
Removing the "Custom Tool" property from the files resolves the issue, but must be done after every code generation.
