PowerShell fails to call .NET method that that has an optional IntPtr parameter whose default value is Int32 0 #19429
Description
Prerequisites
- Write a descriptive title.
- Make sure you are able to repro it on the latest released version
- Search the existing issues.
- Refer to the FAQ.
- Refer to Differences between Windows PowerShell 5.1 and PowerShell.
Steps to reproduce
# !! BROKEN:
# * `default(IntPtr)` (or `default`) are converted to System.Int32(!) 0 on compilation (the same happens in regular .NET SDK probject)
# * C# code can call such a method just fine, but PowerShell complains.
# * Workaround: use `new IntPtr()` as the default value.
(Add-Type -PassThru -Name Foo1 -MemberDefinition @'
public static void Bar(IntPtr p = default(IntPtr)) { }
'@)::Bar()Expected behavior
The method calls should succeed (it produces no output).
Actual behavior
The method call fails with the error below.

Is the issue in 7.3?
[-]Add-Type unexpectedly converts a `default(IntPtr)` default parameter value into `System.Int32`[/-][+]PowerShell fails to call .NET method that that has an optional IntPtr parameter whose default value is Int32 0 [/+]mklement0 commentedon Mar 30, 2023
Ilya (@iSazonov), the issue was framed incorrectly - please see the updated title and initial post.
It is a problem with method invocation, irrespective of whether the code was compiled with
Add-Typeor via a .NET SDK project.The problem also exists in 7.3.3, but not in 7.2.10, and also not in Windows PowerShell.

The Engine WG discussed this and agree it's a bug that should be fixed.
