Descrizione
Description
Throw helpers introduced in https://github.com/dotnet/wpf/pull/8408 caused a behavioral regression thus some double properties no longer accept NaN as a value.
The original condition in net framework and up to net8 was value < 0, the new condition is double.IsNegative(value). The latter now causes an ArgumentOutOfRangeException. See https://github.com/dotnet/runtime/issues/92834#issuecomment-1741525749 on why these are not the same.
Reproduction Steps
// Get an existing visual
TextBox tb = ...
// Prepare some other text using the same parameters
FormattedText ft = new(...);
ft.LineHeight = tb.LineHeight;
Expected behavior
Property value is accepted
Actual behavior
ArgumentOutOfRangeException is thrown
Regression?
Yes. Works in .NET Framework and up to .NET 8
Known Workarounds
In the example above it's simple to fix as NaN is eventually treated as 0 (converted to int.MinValue here then ignored here) though this does not seem intentional.
Other properties may be more difficult to work around
