Failed to retrieve data for this request. (Microsoft.SqlServer.Management.Sdk.Sfc)

Problem: After a while using some tasks like detaching, putting offline, shrinking on SQL Server Management Studio, I couldn't attach a database and the following error appear:

"Failed to retrieve data for this request. (Microsoft.SqlServer.Management.Sdk.Sfc)
An exception occurred while executing a Transact-SQL statement or batch. (Microsoft.SqlServer.ConnectionInfo)"

Refreshing and reconnecting won't work but don't give up...

Solution: Simply Restart SQL Server Management Studio!
