IDE0004 false positive when casting int litral to nint and trying to assign to IntPtr

[Tan90909090]

Version Used:
Microsoft Visual Studio Community 2022 (64-bit) - Current
Version 17.3.6

Steps to Reproduce:

1. Set <LangVersion>10.0</LangVersion> in csproj.
2. Write a following code:

System.IntPtr x = (nint)1;

Expected Behavior:
There is no IDE0004.

Actual Behavior:
There is an IDE0004 Cast is redundant on (nint).
If I remove the cast then I get an error: CS0266 Cannot implicitly convert type 'int' to 'System.IntPtr'. An explicit conversion exists (are you missing a cast?)

Note: The cast may be really redundant when using C# 11 because there is a new feature "numeric IntPtr".

This was changed. This is now always legal (even on langversion10). So it's by design that we offer to remove even then.
