SqlTrackingQuery.GetWorkflows 未获取正确的工作流程

Question

我正在使用 ASP.NET 3.5 和 WF 3.5。

我的代码不断地给我一个 FileNotFoundException。即使我创建了两个工作流实例。它不断尝试获取第一个工作流程（并告诉我程序集不存在），而不是第二个工作流程。这是我的代码：

Dim connectionString As String = ConfigurationManager.ConnectionStrings("LocalWFConnection").ConnectionString

    Dim trackingQuery As SqlTrackingQuery = New SqlTrackingQuery(connectionString)
    Dim options As SqlTrackingQueryOptions = New SqlTrackingQueryOptions()

    Dim workflws As IList(Of SqlTrackingWorkflowInstance)
    Try
        workflws = trackingQuery.GetWorkflows(options)

    Catch ex As SqlException

        workflowError = String.Format("A SQL exception occurred.  Details:<br />{0}", ex.Message)
        Return workflowData

    Catch ex As IO.FileNotFoundException

        workflowError = String.Format("File loading exception occurred. Details:<br />{0}", ex.Message)
        Return workflowData
    End Try

Dim trackingQuery As SqlTrackingQuery = New SqlTrackingQuery(connectionString)
Dim options As SqlTrackingQueryOptions = New SqlTrackingQueryOptions()
options.WorkflowType = GetType(Workflow1) ' where Workflow1 is the name of your Workflow
