CS0102 error while running ASP.NET application
<p>I get this error in the App_directory C# code file,</p>

<p><code>CS0102: The type ClassName already contains a definition for 'mappingSource'</code></p>

<p>It points to line, </p>

<p><code>private static System.Data.Linq.Mapping.MappingSource mappingSource = new AttributeMappingSource();</code></p>

<p>What is the likely mistake? Using vs 2008 and .net 3.5</p>
