XmlSerializatio n and reflection error

[kruskal]

Hi,

do you know why this:

[System.CodeDom. Compiler.Genera tedCodeAttribut e("xsd", "2.0.50727. 42")]
[System.Serializ ableAttribute()]
[System.Diagnost ics.DebuggerSte pThroughAttribu te()]
[System.Componen tModel.Designer CategoryAttribu te("code")]
[System.Xml.Seri alization.XmlTy peAttribute(Ano nymousType = true)]
[System.Xml.Seri alization.XmlRo otAttribute(Nam espace = "", IsNullable
= false)]
public class XmlCostam { ... }

works fine, but this:

[System.CodeDom. Compiler.Genera tedCodeAttribut e("xsd", "2.0.50727. 42")]
[System.Serializ ableAttribute()]
[System.Diagnost ics.DebuggerSte pThroughAttribu te()]
[System.Componen tModel.Designer CategoryAttribu te("code")]
[System.Xml.Seri alization.XmlTy peAttribute(Ano nymousType = true)]
[System.Xml.Seri alization.XmlRo otAttribute(Nam espace = "", IsNullable
= false)]
public class XmlCostam : TabControl { ... }

gives an exception:

System.InvalidO perationExcepti on was unhandled
Message="Wystą pił błąd w czasie wykonywania odbicia typu
'Notebook.XmlCo stam'." (I think in english it means sth like: "there was
an error while processing reflection of type 'Notebook.XmlCo stam'")
