Windows Azure TableServiceContext UndoChanges

When trying to save an object using an illegal character (e.g. '/') in the RowKey an exception is thrown when calling

_tableServiceContext.AddObject(tableName, myEntity);

I get an System.Data.Services.Client.DataServiceRequestException with the info "out of range", which is easily prevented (by preventing or checking for illegal characters).

My question now is, how do I recover from this status? After such an error all succeeding AddObject calls fail, presumably because the "corrupt object" still belong to the context.

Therefore I'm looking for a "UndoChanges" possibility.

Any hints are appreciated, thanks.

P.S.: I'm looking for a better way than to throw away the context or to delete the object from the context...

The best way is probably to detach the entity from the context. If that's not an option for some reason, you could retry the save with SaveChangesOption.ContinueOnErrors set. eg,

_tableServiceContext.SaveChangesWithRetries(SaveChangesOptions.ContinueOnError);

This basically applies all the updates one at a time, instead of in batches. Note it will ignore all errors that occur, not just the one from the illegal entity.
