I'm having a problem with 'SpecialPermissions' its underlined in red (last line of code)

Error 1 'Microsoft.SharePoint.Workflow.SPWorkflowTaskProperties' does not contain a definition for 'SpecialPermissions' and no extension method 'SpecialPermissions' accepting a first argument of type 'Microsoft.SharePoint.Workflow.SPWorkflowTaskProperties' could be found (are you missing a using directive or an assembly reference?)

using System.Collections.Specialized;

private void FC_RemovePendingTask_MethodInvoking(object sender, EventArgs e)
    FC_RemovePendingTask_TaskId1 = Guid.NewGuid();
    FC_RemovePendingTask_TaskProperties1.Title = "Remove Timer";

    FC_RemovePendingTask_TaskProperties1.DueDate = DateTime.Today;

    FC_RemovePendingTask_TaskProperties1.AssignedTo = "S_Financial";

    HybridDictionary permsCollection = new HybridDictionary();

    permsCollection.Add(FC_RemovePendingTask_TaskProperties1.AssignedTo, SPRoleType.Administrator);   

    FC_RemovePendingTask_TaskProperties1.SpecialPermissions = permsCollection;

Raj, no need to use <pre> tag in the code formatting. Using the {} button will format it properly and apply color coding. – Robert Kaucher Mar 16 '14 at 1:43

It's CreateTask itself that has SpecialPermissions not SPWorkflowTaskProperties so you should set in to the CreateTask activity using the taskproperties

I've tried setting it in the tasp properties now. Clicking on special permissions a dialog box pops up but there are no members to select from? How can i add members ? Thanks – Raj Chahal Jun 24 '12 at 8:32
As far as I know you can'd do it in the UI. But in your code you just reference createTask1.SpecialPermissions (Where createTask1 is the name of your activity) instead of FC_RemovePendingTask_TaskProperties1.SpecialPermissions – Per Jakobsen Jun 24 '12 at 8:40
