问题
A few years ago, I asked this question: TFS Custom Check-In Policy is not in the Add box and was able to get my custom check-in policy to work in Visual Studio 2012. I have finally upgraded to VS2015RC and am trying to use the same check-in policy. I have tried to add a reference at the following registry keys:
HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\14.0_Config\TeamFoundation\SourceControl\Checkin Policies
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\VisualStudio\14.0\TeamFoundation\SourceControl\Checkin Policies
but have had no luck. I also opened my check-in policy project in VS2015 and rebuilt it (attempting to target various different frameworks: 4, 4.5, 4.5.1, 4.5.2, 4.6) all with no luck.
I also changed my references of Microsoft.TeamFoundation.versionControl.Client to version 14.0.0.0
Does anyone know why I can't get this policy to show up in the Add Check-In Policy dialog?
回答1:
All that it needed was a night of rest.
This morning I woke up to the Check-In policy working as expected. My computer had restarted overnight which I assume corrected the issue.
I do want to note that while working on this issue yesterday, I tried closing Visual Studio 2015 every time that I changed the registry, etc, but that didn't seem to help. I also logged off/on once and that didn't fix it.
So final answer: computer restart seemed to fix the issue. Also, for future reference, my custom check-in policy is targeting .Net Framework 4.5.1
