Powershell加载二进制模块

Question

I have few powershell script which I am trying to put into module. In the same module I also intend to load ac# dll for token generation. DLL uses System.Management.Automation.

#content of asr.psm1
Import-Module ".\tokengenerator\PowershellTokenGenerator.dll"
Get-ChildItem $psscriptroot\*.ps1 -Recurse | ForEach-Object { . $_.FullName }

The folder tokengenerator includes dll to generate OAuth2.0 token. How can I load powershell module and C# cmdlet under the same module. However, when I am trying to load the module I get the below error.

Import-Module D:\repo\src\aadsr\setup\asr.psm1

Import-Module : The specified module '.\tokengenerator\PowershellTokenGenerator.dll' was not loaded because no valid module file was found in any module directory. At D:\repo\src\aadsr\setup\asr.psm1:1 char:1
+ Import-Module ".\tokengenerator\PowershellTokenGenerator.dll"

Use:

Import-Module "$PSScriptRoot\tokengenerator\PowershellTokenGenerator.dll"

to ensure that the DLL is found relative to the script module's ( *.psm1 ) location, reflected in automatic variable $PSScriptRoot .

By contrast, if you use Import-Module ".\\..." , the DLL is looked for relative to the current location ( . ), whatever it may be.
