Question

Error:

{“The specified type was not recognized: name=’VitalsPlugin’,
namespace=”, at .”}

Code:

public class SimpleSerializer
{
    static void Main()
    {
        string xml = "<Plugin xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xsi:type=\"VitalsPlugin\" ID=\"eaded5f3-7019-47b9-8f9f-e7c1879774f4\"><CopyForwardChecked>true</CopyForwardChecked></Plugin>";
        StringReader reader = new StringReader(xml);
        var result = Deserialize(reader);
    }

    static Plugin Deserialize(TextReader xml)
    {
        XmlSerializer xsr = new XmlSerializer(typeof(Plugin), new Type[] {typeof(VitalsPlugin)});
        Plugin result = xsr.Deserialize(xml) as Plugin;

        return result;
    }
}

Other useful code:

[XmlInclude(typeof(VitalsPlugin))]
public class Plugin
{
}

public class VitalsPlugin
{
}

Answer 1

After much tinkering I ran across a definition of xsi:type. After reading the definition I realized that this type specifies a deriving class. I updated the code to

public class VitalsPlugin: Plugin
{
}

and it works.
