TFS 2017 - Retrieve Trigger information build definitions - tfs

Question

Im trying to retrieve the schedule of the vNext BuildDefinitions through my C# Application.
I can retrieve the BuildDefinition objects that i need.
List<BuildDefinitionReference> builddefs = buildClient.GetDefinitionsAsync().Result;
and
var buildDef = buildClient.GetFullDefinitionsAsync(project: project,
name: buildDefName).Result.ToArray();
But when looking at the BuildDefinition.Trigger information, this does not seem to contain what i need.
Simular to the XAML builds, i want to be able to read the BuildDefinition.Schedules, to see when each build is scheduled.
Who knows where this information is currently kept ?
Update:
Fixed the issue by converting the BuildTrigger to a ScheduleTrigger
if (buildDefinition.Triggers != null)
{
foreach (BuildTrigger trigger in buildDefinition.Triggers)
{
if (trigger is ScheduleTrigger)
{
ScheduleTrigger scheduleTrigger = trigger as ScheduleTrigger;
foreach (var schedule in scheduleTrigger.Schedules)
{
//Do magic
}
}
}
}

Answer 1

Update the Microsoft.TeamFoundationServer.ExtendedClient package to the latest version and the GetFullDefinitionsAsync method should return the schedules information, that are stored in Triggers property instead of Schedules property.

Answer 2

You could use Rest API to Get a build definition, a sample:
GET https://tfsserver:8080/tfs/DefaultCollection/Fabrikam-Fiber-Git/_apis/build/definitions/29?api-version=2.0
Then you will get a response as below which include trigger information:
"triggers": [
{
"schedules": [
{
"branchFilters": [
"+$/MyFirstProject/Test"
],
"timeZoneId": "UTC",
"startHours": 3,
"startMinutes": 0,
"daysToBuild": "all",
"scheduleJobId": "18316444-edbb-479d-950d-7714ba39d3d6",
"scheduleOnlyWithChanges": true
}
],
"triggerType": "schedule"
}
And the each member for your reference:
Members
branchFilters: string[].
daysToBuild: ScheduleDays. Days for a build (flags enum for days of the week)
scheduleJobId: string. The Job ID of the Scheduled job that will queue the scheduled build. Since a single trigger can have multiple
schedules and we want a single job to process a single schedule (since
each schedule has a list of branches to build), the schedule itself
needs to define the Job Id. This value will be filled in when a
definition is added or updated. The UI does not provide it or use it.
startHours: number. Local timezone hour to start
startMinutes: number. Local timezone minute to start
timeZoneId: string. Time zone of the build schedule (string representation of the time zone id)
Details please refer Schedule Rest API.
