[Bug?]Exception Thrown In SSCE 3.5 Beta2 But Not In 3.5 Beta1.

Hi,
I replace the reference assembly System.Data.SqlServerCe with version 3.5 beta2 in Microsoft.Practices.EnterpriseLibrary.Data.SqlCe. When I used the Data.SqlCe block in application, an exception ("Cannot access a disposed object named SqlCeConnection") threw. This didn't occur in SSCE 3.5 beta1 and early versions.
Finally I found the difference between beta1 and beta2.
In the SqlCeConnection class, there is a RemoveWeakReference method. this is code snippet of beta1:





internal void RemoveWeakReference(object value)
{
if (this.weakReferenceCache != null)
{
this.weakReferenceCache.Remove(value);
}
}
and this is for beta2:




internal void RemoveWeakReference(object value)
{
if (this.weakReferenceCache == null)
{
throw new ObjectDisposedException("SqlCeConnection");
}
this.weakReferenceCache.Remove(value);
}




So, if we dispose a connection before a command, such as:
SqlCeConnection cn;SqlCeCommand cmd;... cn.Dispose();cmd.Dispose(); // Error, an exception will be threw. Is it a bug of Beta2?
