[jherby2k]

Analyzer package

Microsoft.CodeAnalysis.FxCopAnalyzers

Package Version

v2.9.0

Diagnostic ID

CA2000

Repro steps

1. Try to dispose a bunch of disposable objects from a concurrent queue:

while (Handles.TryDequeue(out var handle))
                handle.Dispose();

-or-

1. Try to dispose a handle obtained via an out parameter using the IDisposable pattern

readonly CustomNativeHandle _handle;

internal TestConstructor()
{
    NativeMethods.GetHandle(out _handle);
}

public void Dispose()
{
    _handle.Dispose();
}

Expected behavior

No warning - both of these dispose of handles correctly, AFAICT. No warnings under last stable release.

Actual behavior

CA2000 warning
