This very strange issue. When I press the start button to execute the SSIS project it shows "Package part debugging is not supported" and nothing else. I create a control flow with the data flow task and execute SQL task. I have a simple use case to count rows using variable and store package names and the number of rows in a table on the SQL server. When I open error list it shows
Error saving PackagePart1.dtsxp: Control flow package part need to contain exactly one executable.
