Question

我已经用C＃编写了一个Ignite .Net服务，该服务在Linux / NET Core 2.2上运行。现在，我试图在.Net Framework Web应用程序中使用它。

    Ignition.ClientMode = true;

    var igniteCfg = new IgniteConfiguration()
    {
        IgniteHome = System.Web.HttpContext.Current.Server.MapPath(@"~\bin\")
    }; 

    using (var ignite = Ignition.Start(igniteCfg))
    {
        var services = ignite.GetServices();
        IQuoteGeneratorContract proxy = services.GetServiceProxy<IQuoteGeneratorContract>("QuoteService");
        quotes = proxy.GenerateQuotes(quoteRequestMapped);
    }

但是，我在调用Ignition.Start时遇到了一个奇怪的异常：

    Type 'Domain.ElasticCachedReference`1[[Domain.Partner, Utility.Click.Domain, Version=3.10.56.40, Culture=neutral, PublicKeyToken=null]]' in Assembly 'Utility.Click.Domain, Version=3.10.56.40, Culture=neutral, PublicKeyToken=null' is not marked as serializable.

我必须说异常消息是绝对正确的：Domain.ElasticCachedReference类型实际上未标记为[Serializable]。但是，我没有在任何Ignite服务中使用这种类型，也没有将其存储在Ignite缓存中。我只是想在定义和使用此类的同一应用程序中运行Ignite，毕竟，我只是启动Ignite而不是调用任何服务或运行分布式闭包。

我已经查看了Ignite源代码，并怀疑该异常是在Net Framework方法中引发的，并且可能与Activator实例化类型的方式有关，而不是与Ignite本身有关。但是，我想知道如何防止这种异常的发生？谢谢！

我正在运行客户端的计算机上使用以下软件： Windows 10专业版， Visual Studio 2017， C＃7.1，带有ASP.NET的Net Framework 4.7.1， Apache Ignite .Net 2.7

在Net Framework 4.7.1上启动Apache Ignite 2.7时发生序列化异常
