You can use MetadataGet API to get all versions associated with the model and then sort them by CreatedDateTime or
UpdatedDateTime depending how you define "the latest version" .
The code would be like :
var mdGetRequest = new MetadataGetRequest
SearchCriteria =
Models = new Collection<DC.Identifier>()
new DC.Identifier() {Name = "Account"}
ResultOptions = {Versions = DC.ResultType.Identifiers},
// Call MDS service
MetadataGetResponse mdGetResponse = MyServicesApiUtility.MdsService.MetadataGet(mdGetRequest);
if (mdGetResponse.OperationResult.Errors.Count == 0 && mdGetResponse.Metadata.Versions.Count != 0)
var versions = new List<DC.Version>(mdGetResponse.Metadata.Versions);
versions.Sort(
(ver1, ver2) => ver2.AuditInfo.CreatedDateTime.CompareTo(ver1.AuditInfo.CreatedDateTime));
return versions.First();
else
throw new Exception(string.Format("No version related to model {0}.", "Account"));
