Error CS1503 : Argument 2: cannot convert from 'Xml.Schema.Linq.SimpleTypeValidator' to 'System.ReadOnlySpan<char>'

[Foxite]

I have downloaded an RSS schema from here: https://github.com/musiKk/rss-schema/blob/master/src/main/xsd/rss-2.0.xsd

Running LinqToXsd gen -e rss-2.0.xsd produces this file: rss-2.0.xsd.cs

When I put this file into a .NET 10 project that references Xml.Schema.Linq.NetStandard2 1.0.1, there is a single error in the file:

public virtual version? version {
    get {
        XAttribute x = this.Attribute(versionXName);
        if ((x == null)) {
            return null;
        }
        return ((version)(Enum.Parse(typeof(version), XTypedServices.ParseValue(x, XmlSchemaType.GetBuiltInSimpleType(XmlTypeCode.String).Datatype, versionValidator.TypeDefinition))));

Rss.xsd.cs(83,59): Error CS1503 : Argument 2: cannot convert from 'Xml.Schema.Linq.SimpleTypeValidator' to 'System.ReadOnlySpan<char>'

Enum.Parse only takes string and ReadOnlySpan<char> as its second argument, but the XTypedServices.ParseValue call returns the type of its third argument, that being SimpleTypeValidator.

I don't really know what to change about the XTypedServices.ParseValue call to make this compile.

There is no code compilation error that I can see. I downloaded your rss-2.0.xsd.cs file and it compiles fine. I've tested it using <TargetFramework>netstandard2.0</TargetFramework> and also net10 as the target framework. What target are you using please? Please also share any consuming client code. As in, if you're using the generated code from another class/library/app code then share how you're setting or getting the version property.

This is the full CSPROJ file I used to test your rss-2.0.xsd.cs code:

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <TargetFramework>net10.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="XObjectsCore" Version="3.4.13" />
  </ItemGroup>

</Project>

I only received warnings in the build output, no errors:

Edit: I would appreciate a minimal reproducible example.

This is caused by referencing Xml.Schema.Linq.NetStandard2 instead of XObjectsCore. Using the correct package fixes it.

Just want to mention that I indicate the correct package to use in the repo readme file: https://github.com/mamift/LinqToXsdCore#get-started

And also here in the project readme for LinqToXsd: https://github.com/mamift/LinqToXsdCore/blob/master/LinqToXsd/README.md
