Config transformations and “TransformXml task failed” error message
- by Troy Hunt
I’ve just enabled config transformations on a .NET 3.5 project in VS2010 RC after watching Scott Hanselman’s video on web deployment. Unfortunately every time I go to publish I now get the following error:
The "TransformXml" task failed
unexpectedly.
System.UriFormatException: Invalid
URI: The URI is empty. at
System.Uri.CreateThis(String uri,
Boolean dontEscape, UriKind uriKind)

taskExecutionHost, TaskLoggingContext

ItemBucket bucket, TaskExecutionMode

If I take a brand new VS2010 web application which already has the config transformations by default I don’t have a problem so I suspect my issue is project related. Has anyone come across this before or have any ideas on a fix?
