Request for the permission of type 'System.Security.Permissions.SecurityPermission, mscorlib RRS feed

  • Question

  • In my web application i am trying to load the rdlc file by giving a dataset

    RDLC file is been place in my bin folder itself

    I am getting an error below

    The Value expression for the query parameter ‘@ProcessDate’ contains an error: Request for the permission of type 'System.Security.Permissions.SecurityPermission, mscorlib, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed

    @ProcessDate is the first parameter in hte RDLC file.

    I am able to solve the issue by placing security permission like below


    PermissionSet permissions = new PermissionSet(PermissionState



    new SecurityPermission(PermissionState



    new SecurityPermission(SecurityPermissionFlag




    I want to know why this 4 lines above is required, anyway i am loading the RDLC file from my bin folder

    and also it does not have any custom dll refernce.

    Why security permission is rquired to be set?
