Fixes #110147
This change addresses a regression introduced in
Microsoft.Extensions.Configuration.Binder
version 9.0.0. The issue occurs when binding a configuration withErrorOnUnknownConfiguration
set totrue
, where anInvalidOperationException
should be thrown. The regression specifically affects scenarios involving collections, where binding collection values to invalid configuration values does not behave as expected.The original change caused the regression is #97777
The change is ensuring back to the .NET 8.0 behavior, but we should look at fixing the source generator in general with
ErrorOnUnknownConfiguration
.
