I'm currently working on a internal style guide for new colleagues and got stuck while comparing the capitalization content.
So I read the article and discussions here. And there is one aspect I couldn't find or just have missed.

Whats about the function parameter types like:

• String/string
• Integer/integer
• Switch/switch
• PSCustomObject/pscustomobject?

Should these be written in PascalCase oder is there difference between basic types and objects/classes? - In the code snippets of the Code-Layout-and-Formatting article they are in lowercase. So If i get this right, they should be in PascalCase because they match to the rule for .Net Class types, since pwsh types are basically .net Objects?

💡 Example:

function Invoke-FooBar { [CmdletBinding()] #[OutputType([String])] param ( [Parameter(Mandatory = $true)] [String]$MyParam ) begin { } process { } end { } }
