Runtime: DataContractJsonSerializer failing in Microsoft.NetCore.UniversalWindowsPlatform 5.2.2

[kpanwar]

Our library is failing to deserialize blob of data when using Microsoft.NetCore.UniversalWindowsPlatform 5.2.2 in Visual Studio 2015. The deserialization works as expected for 5.1.0 and 5.0.0.

Thanks for opening the issue, @kpanwar. Can you please share a repro app with us? Thanks!

@shmao - I sent you the app link

Thanks for sharing the repro app, Kanishk. I was able to repro the issue on my box. It’s caused by a bug in the de-serialization code. The bug caused that types which are marked with [DataContract] but have non-public default constructor cannot be de-serialized.

We will fix the bug. In the meantime, if you want to use Microsoft.NetCore.UniversalWindowsPlatform 5.2.2 and hit the issue, a workaround is to use the previous release of the serialization packages by adding the following dependencies in project.json,

    "System.Runtime.Serialization.Json": "4.0.1",
    "System.Runtime.Serialization.Primitives": "4.1.0",
    "System.Runtime.Serialization.Xml": "4.1.0",
    "System.Private.DataContractSerialization": "4.1.0"
