解决使用异步方法时报错 does not contain a definition for 'DynamicInvokeAsync 的问题

重现问题方法：

    public async Task<TestTable> GetTestTableRecordBytestTableCode(string testTableCode)
    {
        var TestTableRecord = await _sysCacheService.AdGetAsync<TestTable>(testTableCode, async () => {
            var TestTableRecords = await _TestTableService.GetTestTableRecordListBytestTableCode(testTableCode);
            // ..... 其他一些处理 ........

            return TestTableRecords.FirstOrDefault();
        }, new TimeSpan(0,30,0)); //按照30分钟的缓存期

        return TestTableRecord;
    }
