如何返回指定.NET程序集的公共类和过时类的列表？

问：

该函数应返回公共但过时的类列表

public static IEnumerable<string> GetPublicObsoleteClasses(string assemblyName)
        {
            return Assembly.ReflectionOnlyLoad(assemblyName).GetTypes()
                .Where(x => x.IsClass &&
                            x.IsPublic &&
                            Attribute.GetCustomAttributes(x)
                                .Any(y => y is ObsoleteAttribute))
                .Select(x => x.Name);
        }

但是，它显示此平台不支持 ReflectionOnly 加载。

此方法有一个单元测试，不允许更改它

[Test ]
         
        public void GetPublicObsoleteClassesShouldReturnRightList()
        {
            var expected = "CaseInsensitiveHashCodeProvider, ContractHelper, ExecutionEngineException, "+
                           "FirstMatchCodeGroup, IDispatchImplAttribute, PermissionRequestEvidence, "+
                           "SecurityTreatAsSafeAttribute, SetWin32ContextInIDispatchAttribute, "+
                           "UnionCodeGroup, UnmanagedMarshal";

            var obsoleteMembers = CommonTasks.GetPublicObsoleteClasses("mscorlib, Version=4.0.0.0").OrderBy(x=>x);
            var actual = string.Join(", ", obsoleteMembers);
            Assert.AreEqual(expected, actual);
        }
