Test case - works on .NET, crashes on Mono

IsolatedStorageFile.CreateDirectory does not accept paths that are rooted ('/foo/bar/baz') due to the way it splits the path along the directory separator char:

https://github.com/mono/mono/blob/1a843974f3951a4fffdd9120c8bcd649738d8189/mcs/class/corlib/System.IO.IsolatedStorage/IsolatedStorageFile.cs#L582

On .NET this is not a problem, the two paths are treated as the same:

/foo/bar/baz
foo/bar/baz

Attached is a test case and a possible (untested) patch.

If there are any test cases, they should be updated to test rooted paths.
Comment 2 Sebastien Pouliot 2012-05-22 14:42:18 UTC
Fixed at split-time and also when deleting directories.
