Import-Csv Should apply PSTypeNames uppon import when Type Information is present in the CSV #5134
Description
The seemingly only useful way to use the Type Information currently added by default during Export-Csv would be to reapply the PSTypeNames to the PSCustomObjects. Currently, These Type names are currently prepended with CSV:. This means that exporting a simple PSObject to CSV and then re-importing would require 2 format definitions or add/set the PSTypeNames for the imported objects.
Steps to reproduce
[PSCustomObject]@{
PSTypeName = 'My.Custom.Object'
Column1 = 'values1'
} | Export-Csv C:\temp\csv.csv
$import = Import-Csv C:\temp\csv.csv
$import.PSObject.TypeNamesExpected behavior
My.Custom.Object
Actual behavior
CSV:My.Custom.Object
