Back coding in Visual Studio for awhile and today have slogged through two frustrating problems. Solutions are recorded to save me troubleshooting time in the future.

COM object that has been separated from its underlying RCW cannot be used. It turns out for me the answer was to uninstall the C# Source Code Analysis plugin. Found the answer on the msdn site .

Our setup is an IBM BladeCenter with a combination of HS21 and HS21XM blades connected to an IBM DS3400 Fiber Channel SAN. We purchase our blades without drives and boot from the SAN. This works great once in production but has proved tricky to get into production (if you are like us and only do this every once in a while).

That controller owner setting must sync up with which HBA controller you have defined as the boot device. On our DS3400 screen that setting is under Modify/Change Logical Drive Ownership/Preferred Path. Without that setting t...
