Errors using a Customized Build Template to generate a Build in TFS 2015

Hi everyone.

After a migration from TFS 2010 to TFS 2015, when I try to generate a Build using a customized build template, that was created in 2010, the following error occurs:

"TF215097: An error occurred while initializing a build for build definition \SWPR19-RISK-V1\Build-PRU-WEB-EVO: Exception Message: The type ‘InArgument(ce:DictionaryContainer)’ of property ‘ConfigValues’ could not be resolved. (type Exception)Exception Stack Trace: at Microsoft.TeamFoundation.Build.Hosting.BuildProcessCache.LoadFromXaml(String workflowXaml, TextExpressionImports textExpressionImports) at Microsoft.TeamFoundation.Build.Hosting.BuildControllerWorkflowManager.PrepareRequestForBuild(WorkflowManagerActivity activity, IBuildDetail build, WorkflowRequest request, IDictionary`2 dataContext) at Microsoft.TeamFoundation.Build.Hosting.BuildWorkflowManager.TryStartWorkflow(WorkflowRequest request, WorkflowManagerActivity activity, BuildWorkflowInstance& workflowInstance, Exception& error, Boolean& syncLockTaken)"

I have tried to export a customized Build Template (created in 2010) and then added it to 2015, but when trying to edit from VS 2015, the following error appears:

System.Xaml.XamlException: 'The type ‘InArgument(ce:DictionaryContainer)’ of property ‘ConfigValues’ could not be resolved.' Line number '70' and line position '37'.

When I try to add the customized Build Template, in order to use it to generate a Build I see the following error:
