Closed Unassigned: Exception in System.Data.Entity.Core.Common.DbProviderServices.ExpandDataDirectory(String path) [2965]

i have a clickonce deployed WPF application where we have marked our SQL Local database as a data component. At times when the clickonce is upgraded our database is kind of inaccessible from the application and all DB operations fail.

Following log is seen in the log file:
Database Initialization Failed : __Expansion of |DataDirectory| failed while processing the connection string. Ensure that |DataDirectory| is set to a valid fully-qualified path__.
System.ArgumentException: Expansion of |DataDirectory| failed while processing the connection string. Ensure that |DataDirectory| is set to a valid fully-qualified path.

at System.Data.Entity.Migrations.DbMigrator.EnsureDatabaseExists(Action mustSucceedToKeepDatabase)
at System.Data.Entity.Migrations.DbMigrator.Update(String targetMigration)

When i went to the code piece(in bold above) I can see a if block like this:
// Verify root folder path is a real path without unexpected "..\"
if (rootFolderPath.Contains(".."))
{
throw new ArgumentException(Strings.ExpandingDataDirectoryFailed);
}


When we watched the location of the data folder, it was something like this:
__C:\Users\<USERNAME>\AppData\Local\Apps\2.0\Data\98O56D2Q.EM1\R4LXLEL4.85M\tech..tion_0000000000000000_0003.0001_80c92a08f8b673c0\Data__


So it results that our path at __"tech..tion_0000000000000000_0003.0001_80c92a08f8b673c0"__ do contains __(..)__.

But based on the if block check this actually does not satisfies the condition because it is not at the start of the folder location.

As per my suggestion the if block should be like:
// Verify root folder path is a real path without unexpected "..\"
if (rootFolderPath.StartsWith("..\", StringComparison.Ordinal))
{
throw new ArgumentException(Strings.ExpandingDataDirectoryFailed);
}


Please suggest what should I do as the install folder path is not under control. The name and path is decided by the clickonce deployment strategy. Waiting for your reply.
