app.UseMiddleware(typeof(Catch),
    System.Net.HttpStatusCode.InternalServerError,
    new WithContentType("text/xml"),
    new XmlDigest(
        new BoBo.Formatting.XML.RecursiveDump(
            new XmlDump()
        )
    )
);

Generated XML

<Exception>
  <Message>wow</Message>
  <Dump>
    <Frame>
      <File>C:\projects\BoBo\BoBo.ASPNETCore.TestEndpoints\Controllers\SampleController.cs</File>
      <Method>Get</Method>
      <LineNumber>14</LineNumber>
    </Frame>
    <Frame>
      <File>C:\projects\BoBo\BoBo.ASPNETCore\Middleware\Catch.cs</File>
      <Method>MoveNext</Method>
      <LineNumber>31</LineNumber>

    new JsonDigest(
        new BoBo.Formatting.JSON.RecursiveDump(
            new JsonDump()
        )
    )
);
