签名F＃程序集（强名称组件）

问题描述

我在CodeProject上发现这篇文章：

I found this article on CodeProject:http://www.codeproject.com/Articles/512956/NET-Shell-Extensions-Shell-Context-Menus

，并认为这将是很好的给它尝试，但在F＃。所以我想出了以下代码：

and thought it would be nice to give it a try, but in F#. So I came up with the following code:

open System
open System.IO
open System.Text
open System.Runtime.InteropServices
open System.Windows.Forms
open SharpShell
open SharpShell.Attributes
open SharpShell.SharpContextMenu

[<ComVisible(true)>]
[<COMServerAssociation(AssociationType.ClassOfExtension, ".txt")>]
type CountLinesExtension() =
    inherit SharpContextMenu.SharpContextMenu()

    let countLines =
        let builder = new StringBuilder()
        do
            base.SelectedItemPaths |> Seq.iter (fun x -> builder.AppendLine(sprintf "%s - %d Lines" (Path.GetFileName(x)) (File.ReadAllLines(x).Length)) |> ignore  )
            MessageBox.Show(builder.ToString()) |> ignore

    let createMenu =
        let menu = new ContextMenuStrip()
        let itemCountLines = new ToolStripMenuItem(Text = "Count Lines")
        do
            itemCountLines.Click.Add (fun _ -> countLines)
            menu.Items.Add(itemCountLines) |> ignore
        menu

    override this.CanShowMenu() = true
    override this.CreateMenu() = createMenu

但是，我注意到在VS2012中不支持签名一个F＃程序集（文章中的第4步）。我学会了，如果我想这样做，我需要手动创建一个键（在命令提示符中键入sn -k keyName.snk），然后在项目属性 - >生成 - >其他标志 --keyfile：keyName.snk）。

However, I noticed that there is no support for signing an F# assembly in VS2012 (step 4. in the article). I learnt that if I want to do so, I need to create a key manually (typing "sn -k keyName.snk" into the command prompt) and then add a flag in "Project Properties -> Build -> Other Flags" (--keyfile:keyName.snk).

我仍然无法成功运行此操作。此外，使用作者的应用程序（在调试Shell扩展部分）我得到一个错误，我的程序集不包含COM服务器。

I still didn't manage to successfully run this. Moreover, using the author's application (in "Debugging the Shell Extension" section) I get an error that my assembly doesn't contain a COM server.

做错事与签署组件。

推荐答案

一个签署F＃程序集的方法是通过 AssemblyFileKeyAttribute

One way to sign an F# assembly is via the AssemblyFileKeyAttribute attribute.

创建一个新模块：

module AssemblyProperties

open System
open System.Reflection;
open System.Runtime.InteropServices;

[<assembly:AssemblyKeyFileAttribute("MyKey.snk")>]

do()

其中MyKey.snk是相对于项目目录的密钥路径。

Where "MyKey.snk" is the path to your key relative to the project directory.

另一种方式，在这个错误报告中找到，是将 - 密钥文件：MyKey.snk 添加到 属性中的其他标志字段>创建标签。

Another way, as found in this bug report on Microsoft Connect, is to add --keyfile:MyKey.snk to the Other Flags field in the Properties --> Build tab.

使用任一方法;运行 sn -v myfsharpassembly.dll 将断言程序集在编译后有效。

Using either approach; running sn -v myfsharpassembly.dll will assert that the assembly is valid after compilation.
