[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?

This is a issue in Beta2. Most probably we will fix in SSCE 3.5 RTM.

The Bug Id: 13211 tracks this issue.
