[srxqds]

Description

 Type dictConcrete = typeof(Dictionary<int, int>);
Type[] concreteNestedTypes = dictConcrete.GetNestedTypes(BindingFlags.Public | BindingFlags.NonPublic);

foreach (var type in concreteNestedTypes)
{
    Console.WriteLine($"nestedType {type}");
}

the code show print different between coreclr and mono:

coreclr:

nestedType System.Collections.Generic.Dictionary`2+Entry[System.Int32,System.Int32]
nestedType System.Collections.Generic.Dictionary`2+Enumerator[System.Int32,System.Int32]
nestedType System.Collections.Generic.Dictionary`2+KeyCollection[System.Int32,System.Int32]
nestedType System.Collections.Generic.Dictionary`2+ValueCollection[System.Int32,System.Int32]
nestedType System.Collections.Generic.Dictionary`2+KeyCollection+Enumerator[System.Int32,System.Int32]
nestedType System.Collections.Generic.Dictionary`2+ValueCollection+Enumerator[System.Int32,System.Int32]

mono:

nestedType System.Collections.Generic.Dictionary`2+Entry
nestedType System.Collections.Generic.Dictionary`2+Enumerator
nestedType System.Collections.Generic.Dictionary`2+KeyCollection
nestedType System.Collections.Generic.Dictionary`2+ValueCollection
...
