The binary module defines a provider that has a default PSDrive.\r\nWhen calling `Get-ChieldItem \u003cqualified path\u003e` it fails with \"Cannot find a provider with the name '...'\". This has changed since 6.0 when it used to work.\r\n\r\nI have created a sample repro module:\r\n\r\n[ReproProviderNameMismatch.zip](https://github.com/PowerShell/PowerShell/files/3261220/ReproProviderNameMismatch.zip)\r\n\r\nSummary:\r\n- The module must be nested to get this to reproduce\r\n- The provider must do something at initialization time that triggers a capture of the Provider.FullName (or something like that). In my case this is the PSDriveInfo constructor probably:\r\n```c#\r\n      protected override Collection\u003cPSDriveInfo\u003e InitializeDefaultDrives() {\r\n         var drive = new PSDriveInfo(\r\n            \"defaultSampleDrive\",\r\n            ProviderInfo,\r\n            \"/\",\r\n            \"Sample default drive\",\r\n            null);\r\n         var result = new Collection\u003cPSDriveInfo\u003e {drive};\r\n         return result;\r\n      }\r\n```\r\n\r\n**If the InitializeDefaultDrives in the sample is removed, then the issue would not be reproduced.**\r\n\r\n# Steps to reproduce\r\n1. Build the sample module with `dotnet build`\r\n2. Load the module from the build output and run the following:\r\n```powershell\r\nimport-module \"...ReproModule.psd1\"\r\n\r\nNew-PSDrive -Name \"prv1\" -Root \"/\" -PSProvider \"SamplePrv\"\r\n\r\n$item = get-item \"prv1:\\test.txt\"\r\n$item | fl *\r\n\r\nGet-ChildItem $item.PSPath\r\n```\r\n3. Observe the PSPath value\r\n\r\n# Expected behavior\r\nThe command to return the item like this:\r\n\r\n```none\r\nPSPath                          PSProvider            PSIsContainer Name\r\n------                          ----------            ------------- ----\r\nReproModule\\SamplePrv::test.txt ReproModule\\SamplePrv         False test.txt\r\n```\r\nProbably the PSPath value should be:\r\n```\r\nPSPath        : ReproModule\\SamplePrv::test.txt\r\n```\r\n\r\n# Actual behavior\r\nPSPath value is:\r\n```\r\nPSPath        : module\\SamplePrv::test.txt\r\n```\r\n\r\nThe command fails with:\r\n\r\n```none\r\nGet-ChildItem : Cannot find a provider with the name 'module\\SamplePrv'.\r\nAt line:1 char:1\r\n+ Get-ChildItem $item.PSPath\r\n+ ~~~~~~~~~~~~~~~~~~~~~~~~~~\r\n+ CategoryInfo          : ObjectNotFound: (module\\SamplePrv:String) [Get-ChildItem], ProviderNotFoundException\r\n+ FullyQualifiedErrorId : ProviderNotFound,Microsoft.PowerShell.Commands.GetChildItemCommand\r\n```\r\n\r\n# Environment data\r\n\r\n```none\r\nName                           Value\r\n----                           -----\r\nPSVersion                      6.2.1\r\nPSEdition                      Core\r\nGitCommitId                    6.2.1\r\nOS                             Microsoft Windows 10.0.17763\r\nPlatform                       Win32NT\r\nPSCompatibleVersions           {1.0, 2.0, 3.0, 4.0…}\r\nPSRemotingProtocolVersion      2.3\r\nSerializationVersion           1.1.0.1\r\nWSManStackVersion              3.0\r\n```\r\n","author":{"url":"https://github.com/atanasa","@type":"Person","name":"atanasa"},"datePublished":"2019-06-06T11:05:42.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":14},"url":"https://github.com/9840/PowerShell/issues/9840"}
