Compiler Error CS0641
'attribute' : attribute is only valid on classes derived from System.Attribute
An attribute was used that can only be used on a class that derives from System.Attribute.
The following sample generates CS0641:
// CS0641.cs
using System;
[AttributeUsage(AttributeTargets.All)]
public class NonAttrClass // CS0641
// try the following line instead
// public class NonAttrClass : Attribute
{
}
class MyClass
{
public static void Main()
{
}
}
