I've coded up an Ignite .Net service in C# which is running on Linux/NET Core 2.2. Now I'm trying to consume it in a .Net Framework web application.

    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);

    }

However, I am getting a strange exception when calling Ignition.Start:

    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.

I need to say that the exception message is absolutely correct: The type Domain.ElasticCachedReference is really not marked as [Serializable]. However, I am not using this type in any Ignite service and not storing it in Ignite cache. I am just trying to run Ignite in the same application where this class is defined and used, and after all, I am just starting Ignite and not yet calling any service or running a distributed closure.

I've reviewed the Ignite source code and suspect that the exception is thrown in a Net Framework method and is likely to be related to how a type is instantiated by Activator rather than to Ignite itself. However, I am wondering how I can do to prevent this exception from occurring? Thank you!

I'm using the following software on the machine where the client is running:
Windows 10 Pro,
Visual Studio 2017,
C# 7.1,
Net Framework 4.7.1 with ASP.NET,
Apache Ignite .Net 2.7
