Failed to Convert XMLReader to Mono Code

[ppun51]

Steps to Reproduce

1. Create sample project
2. reference the System.XML
3. Add Deserialization method using XMLReader
4. use Embeddinator to convert the project to the library.

   Expected Behavior

   Generate library without error.

   Actual Behavior

   error is occurred "Failed to convert XMLReader to MonoCode

   Environment

public void Deserialize(XmlReader reader) { // get the values this.A = float.Parse(reader.GetAttribute(RGB_A)); this.R = float.Parse(reader.GetAttribute(RGB_R)); this.G = float.Parse(reader.GetAttribute(RGB_G)); this.B = float.Parse(reader.GetAttribute(RGB_B));

        // read the element
        reader.Read();
        reader.ReadEndElement();
    }

[rolfbjarne]

Thank you for your feedback!

For us to investigate this further, could you please provide the full build log, a test project to reproduce and all your version information.

The easiest way to get exact version information:

• On Visual Studio for Mac: "Visual Studio" menu, "About Visual Studio" item, "Show Details" button.
• On Visual Studio for Windows: "Help menu", "About Microsoft Visual Studio" item.

Then copy/paste the version information (you can use the "Copy Information" button).

We look forward to hearing from you!
