powershell dll method not found

I have a PowerShell script where I want to set a Value in some method. I use a dll, and I now these methods exists in this dll file.

But for some reason, I still get a method not found exception.

I updated the dll and printed the filename, in my script, so I am sure that my script using the right dll. I checked the dll and the method exist.

In the same file, I have another method that I use, en this works perfectly.

I thought maybe I had a writing error but didn't found one.

$messagingDllPath = Join-Path -Path $PSScriptRoot -ChildPath 'dll/OneHIP.Messaging.dll' | Resolve-Path
Add-Type -Path $messagingDllPath # Add assembly

[OneHIP.Messaging.Configuration.ApplicationSettingsProvider]::SetValue("ClientId","idValue")

[OneHIP.Messaging.Configuration.ApplicationSettingsProvider]::SetValue("ClientSecret","secret")

<member name="M:OneHIP.Messaging.Configuration.ApplicationSettingsProvider.SetValue(System.String,System.String)">
            <inheritdoc/>
</member>

Does somebody have an idea what the problem is here?

Check if the method is known to PowerShell by using Get-Member:

$ObjectInstance | Get-Member

Add the -Static switch to see the static methods:

$ObjectInstance | Get-Member -Static

This latter option also works with types directly:

[TypeName] | Get-Member -Static

You are using PowerShell's static method calling convention (i.e. using the :: operator). If it isn't static (which you've since confirmed), you'll need to create an instance of your type first (with New-Object), then call with the instance method syntax (i.e. with the . operator).

The method was not Static.

By creating a new instance, I was able to call the SetValue method.

Thanks to @boxdog
