AspNetCore 1.4.0

New Features

• Fully tested on .NET 10
• Return status code 400 (Bad Request) on parameter errors such as null when null is not allowed (#551, #546)
• Added support for XML serialization as an alternative to binary serialization format (#546)

  • Server can now intelligently handle both binary and XML content types

    var builder = WebApplication.CreateBuilder(args);
    builder.Services.AddOpenRiaServices(o => { } )
        .AddXmlSerialization();

Bugfixes

• #553 - Buffer management bug for responses - small probability but HIGH SEVERITY bug
• #552 - Incorrect decoding of string parameters

EntityFrameworkCore 4.0

• Add .NET 10 target framework compiled against EF Core 10 (#549)
  • NOTE: EF Core 10 contains BREAKING CHANGES, ensure all other assemblies are compiled against EntityFrameworkCore 10

Core libraries (5.7.0)

Major Features

• DateOnly and TimeOnly (#539, #540)

  DateOnly and TimeOnly are now fully supported primitive type, but REQUIRES .NET 10 runtime for serialisation.

• XML Support

  Added a new class OpenRiaServices.Client.DomainClients.XmlHttpDomainClientFactory that can be used to enable text-based XML communication with the server.

  Sample usage:

  DomainContext.DomainClientFactory = new XmlHttpDomainClientFactory(baseUri, httpClientFactory);

Server

• EntityAssociationAttribute should now be used instead of AssociationAttribute (which is obsolete on .NET)
  • While there is code for backwards compatibility, please update all code to use the new attribute since backwards compatibility may be removed in the future

Client

• Improves clients NotFound errors (will now use OperationErrorStatus.NotFound)
• Fix handling of empty string, when returned from invoke method (POST), it was incorrectly converted to null on client

• Replace ReaderWriterLockSlim with ConcurrentDictionary for improved perf in DataContractSurrogateGenerator (#529)
• Updated some dependencies
• Update CI pipelines - running VS 2026 and compiling using C#14
• Running many tests on .NET 10
