Though the only
known solution is re-build these custom WSP’s using best practices, its important
to develop a detailed report on each custom assemblies on GAC and provide a
report to fix these issues. So idea is to build a powershell script to
1) Export all
the WSP solutions
2) Extract the
WSP’s
3) Run SPDispose
check on each DLL
4) Identify the
assembly is in “Debug” or release mode
5) Export the
report to CSV
