Change Description

When targeting the .NET Framework 4.5 in the workflow designer, and loading a re-hosted 3.5 workflow with the WorkflowDesigner.Load() method, a XamlDuplicateMemberException is thrown while saving the workflow.

• Quirked
• Build-time break

Recommended Action

This bug only manifests when targeting .NET Framework 4.5 in the workflow designer, so it can be worked around by setting the WorkflowDesigner.Context.Services.GetService<DesignerConfigurationService>().TargetFrameworkName to the 4.0 .NET Framework.

Alternatively, the issue may be avoided by using the WorkflowContext.Load(string) method to load the workflow, instead of WorkflowDesigner.Load().

Affected APIs

• M:System.Activities.Presentation.WorkflowDesigner.Load
