BTDF deploy on local machine in Visual Studio by using “Tools”, “Deployment Framework for BizTalk”, “Deploy BizTalk Solution” failed with the following error in XmlPreprocess.exe

/s:: Argument expects a parameter

What caused the error for me was that I in the SettingsFileGenerator.xml spreadsheet, I had renamed all the “Settings File Names” for each environment.  I switched the “Local Development” back to Exported_LocalSettings.xml and this got around the issue.

Perhaps there is a setting in the .btdfproj file that allows you to specify (override) the local settings name, but I couldn’t find it today.
