Description

Actual behavior

When using DECIMAL to decimal conversion from a stored DECIMAL inside a VARIANT or PROPVARIANT than Visual Studio Debugger can not show the converted decimal value.
I think this problem comes with optimization of conversion in issue #1512.

Expected behavior

The Debugger should show the correct decimal value.

Repro steps

  1. NativeMethods.txt content:
VARIANT
PROPVARIANT
VARENUM
DECIMAL
  1. NativeMethods.json content (if present):
  1. Any of your own code that should be shared?
    See project

ConsoleApp1.zip
Set a breakpoint at the end of Program.Main and have a look with the debugger to the variables result and correct.

Context
  • CsWin32 version: [0.3.264]
  • Win32Metadata version (if explicitly set by project):
  • Target Framework: [net8.0]
  • LangVersion (if explicitly set by project): [e.g. 9]

Research direction

Start with the attached ConsoleApp1.zip, NativeMethods.txt, and any NativeMethods.json, then run the repro and inspect result and correct at the breakpoint at the end of Program.Main. Read issue #1512 for the related conversion optimization and compare the debugger's displayed values. Done means the converted DECIMAL value inside VARIANT or PROPVARIANT displays correctly.
