I have created a Permission Attribute and used it in my methods written in

  • 0

I have created a Permission Attribute and used it in my methods written in my BLL. It works fine and debug well if i need to. But when i used the same attribute in my WCF layer it simply stops working. Not giving any error but permissions has not been checked and no debugging. Code is just ignoring the attribute.

To make things simple i use this approach

My WCF methods calls another methods defined in the same class as the WCF methods and that child method calls the BLL and this child method has the Permission Attribute on it.

But no use. Kindly guide.

    PostSharp is part of the build process. I suspect the library which contains your WCF services don’t run the PostSharp post-compilation process which interweaves the attribute code with your own. If it doesn’t your breakpoints…etc. for the PostSharp code will not work.

    Usually the post-compilation process is done by a background application that resides in the system tray on your development PC. It can be disabled however. I don’t know how you are compiling the WCF service libraries.

    You can manually add PostSharp to your project:

    To quote the PostSharp documentation:

    1. Open the project file (csproj, vbproj, …) using a text editor. If your project is loaded in Visual Studio, open the Solution Explorer, right-click on the project name, click on Unload project, then right-click again on the same project and click on Edit.

    2. Locate the elements near to the end of the file. For instance, a C# 2.0 project should end with an element similar to this:

      <Import Project=”$(MSBuildBinPath)\Microsoft.CSharp.targets” />

    3. Before the import line, insert the following text:

      <PropertyGroup><DontImportPostSharp>True</DontImportPostSharp></PropertyGroup>

    4. After the C# / VB import line, insert the following text:

      <Import Project=”….\Third Party\PostSharp 2.0\PostSharp.targets” />

    5. Save the file and reload the project.

    6. Compile.

    If you are are calling methods from your BLL assemblies please check if the PostSharp post-compilation process is also run correctly.
