Description
All WPF apps will spend now spend considerable time on startup verifying legacy accessibility switches setting. First it uses reflection to gather
UseNetFx47CompatibleAccessibilityFeatures/UseNetFx471CompatibleAccessibilityFeatures/UseNetFx472CompatibleAccessibilityFeatures, then it orders and creates an array to go through its values, which is just a major overkill and this early it results in a big JITTing overhead besides other things.As I personally don't think those properties are gonna grow in the direction where we would need such an over-engineered solution, I've decided to simplify it. This will improve the start-up time of all WPF apps.
Customer Impact
Improved start-up time, decreased start-up allocations.
Regression
No.
Testing
Local build.
Risk
Low, this removes an over-engineered solution for a simple logic evaluation.
