The error "configuration system failed to initialize" occurred

Question

Hi
When I converted and built the solution file that was developed by Visual Studio .net 2003 using Visual Studio 2005, the application program was abnormal-ended at the following step:
m_TCPChannel = New System.Runtime.Remoting.Channels.Tcp.TcpChannel(tcp_properties, Nothing, Nothing)
The error message was "configration system failed to initialize".  The Exception.ToString said that the root <configuration> tag was not included in the configuration file. Therefore, I changed <configopt> tag to <configuration>
tag in the app.config file of the target project, and then executed again. Next time, the application program was abnormal-ended by the unrecognized section <xs:schema>. Therefore, I changed the app.config file to the simple one (only <configuration>
and </configuration> tags), and then executed again. The error didn't occur. I guess that it's caused by configuration settings. Please advise.
app.config file:
<?xml version="1.0" standalone="yes"?>
<configopt>
<xs:schema id="configopt" xmlns="" xmlns:xs="URLリンク" xmlns:msdata="urn:schemas-microsoft-com:xml-msdata">
<xs:element name="configopt" msdata:IsDataSet="true" msdata:Locale="en-AU">

Hi,
Thank you for your post.
I am afraid that the issue is out of support range of VS General Question forum which mainly discusses the usage of Visual Studio IDE such as
WPF & SL designer, Visual Studio Guidance Automation Toolkit, Developer Documentation and Help System
and Visual Studio Editor.
Since your issue occurred on the converted project from VS .net 2003 to VS2005, and VS2005 is out of
our mainstream support , I suggest that you should consult on some development forums to check whether they will to provide some suggestions or
submit a support ticket to below site,

Thank you for your understanding.
