Solution reload after close

Currently, once the application has "grabbed" the solution, there is no release when solution is closed. Attempts to keep using the application once a solution has closed will not enable the solution to reopen.
Possibly need some release method.

No files, tests, or entry points are identified in the issue. Start by tracing how the application grabs a solution and what happens when that solution closes; determine where release handling belongs. Done means the application can continue being used and can reopen a solution after the previous one closes.
