If I run the Custom Tool on the tt templates with a linked app.config (from another project), then I get this error:
Error 208 Running transformation: System.ArgumentException: Format of the initialization string does not conform to specification starting at index 0. at System.Data.Common.DbConnectionOptions.GetKeyValuePair(String connectionString, Int32 currentPosition, StringBuilder buffer, Boolean useOdbcRules , String& keyname, String& keyvalue)
If I copy the app.config in the project where I run the Custom Tool, it works fine.
Any idea how to solve this so I can work with a linked app.config?
