Hi. We run 2012 enterprise. I have to collect more details but thought I'd post what I suspect is a disconnect between conn strings we're sending to our webservice proxy client call from ssis c# script component and ssis's ability to config same to an ssis conn manager.
We send a conn string with this format to our webservice proxy client as a method argument...
data source=x;initial catalog=y;integrated security=True;MultipleActiveResultSets=True;App=EntityFramework
...but seem to be forced into using the following format if we're to have any success marking a conn's connection string an expression that is mapped from a variable (where conn mgr is used in other ssis data sourcing components)...
Data Source=x;Initial Catalog=y;Provider=SQLNCLI11.1;Integrated Security=SSPI;multipleactiveresultsets=True;app=EntityFramework
...and conversely our proxy client fails if we send the conn string that works for data sourcing expression based conn mgrs.
