<!--
FEATURE_VALUETASK_SOURCES_MANUALRESET: ManualResetValueTaskSourceCore<T> is available.
The compatibility package provides this type on .NET Standard >= 2.0, but not on .NET Framework
or on .NET Standard < 2.0. On .NET Core >= 2.1 and .NET Standard >= 2.1, it is available natively.
This type is only available natively on .NET Core >= 2.1 and .NET Standard >= 2.1.
The System.Threading.Tasks.Extensions compatibility package does NOT provide this type
for .NET Standard 2.0 or .NET Framework targets — only IValueTaskSource<T> and related
types are included there.
