Is PresentationCore built with Debug configuration? #1766

Closed omariom closed 5 years ago

omariom commented 5 years ago

.NET Core Version: 3.0.0-preview8-28405-07, 3.0.0-preview6-27804-01
Windows version: 1903
Does the bug reproduce also in WPF for .NET Framework 4.8?: No
Is this bug related specifically to tooling in Visual Studio (e.g. XAML Designer, Code editing, etc...)? No

Problem description:

While looking at the jitted code of PresentationCore, found that the code was not optimized. Turned out the assembly has optimizations explicitly disabled.

Yep, we discovered this as part of an investigation into #1549. Long story short, we inject a module constructor into PresentationCore via IL(D)Asm and had incorrect settings leading to the wrong parameters being used for the DebuggableAttribute.

This was already fixed recently. Closing as a duplicate.
