'Use base type where possible' creates duplicate interface constraint

Created: 23 Aug 06 16:01   Updated: 14 Apr 08 14:15
Component/s: Refactorings - Use Base Type Where Possible
Fix Version/s: Aroha
Security Level: Everybody (All jira users)

Original Estimate: Unknown Remaining Estimate: Unknown Time Spent: Unknown

Build: 258


 Description  « Hide 
using System;
internal class Generic<T> : ICloneable where T : Generic<T>, ICloneable
{
	public object Clone()
	{
		return MemberwiseClone();
	}
	
	public static Generic<T> Clone(Generic<T> obj)
	{
		return (Generic<T>) obj.Clone();
	}
}

Apply 'use base type' for Generic<T>. Select base type ICloneable.
Exception will occur and wrong code is generated:

using System;
internal class Generic<T> : ICloneable where T : ICloneable, ICloneable
{
	public object Clone()
	{
		return MemberwiseClone();
	}
	
	public static ICloneable Clone(ICloneable obj)
	{
		return (Generic<T>) obj.Clone();
	}
}
