I have an Check-In-Policy extension for VS2017 (using TFS 2017) that checks if the pending check-in contains files matching a given regex.

In case matching files are contained in CheckedPendingChanges the Evaluate method returns the PolicyFailure to avoid checking in these files.

[Serializable]

public class FileWarningPolicy : PolicyBase

{

   // ...



   public override PolicyFailure Evaluate()

   {

        Regex regex = new Regex(Pattern, RegexOptions.Compiled | RegexOptions.IgnoreCase);

        if (PendingCheckin.Policies.EvaluationState != PolicyEvaluationState.Evaluated) return new PolicyFailure[0];                

        var matchingFiles = from change in PendingCheckin.PendingChanges.CheckedPendingChanges                                   

                            where change.IsEdit && regex.IsMatch(change.ServerItem)

                            select change;               



        return matchingFiles.Any()

               ? new  { new PolicyFailure("some error message", this)

               : new PolicyFailure[0];



    }

}

This works fine. But it would be far more comfortable if I were able to simply "uncheck" these files to exclude them from the current check-in but not abort the whole check-in.

Through the PendingCheckin.PendingChanges property I have access to the current Workspace which has a lot of methods to download, check-in, check-out, shelve etc. the repository items, but nothing to only uncheck/exclude them from the checked pending changes (only to add an exclude entry to .tfignore, which is not what I want).

Is there a way to achieve this?
