PreEmptive Dotfuscator在Xamarin上不起作用

Question

我正在使用PreEmptive混淆程序(Dotfuscator)来混淆一个Xamarin应用程序。我的问题是，混淆器不会混淆我的项目dll。当我在模糊处理后打开dll时，我仍然看到可读的信息。当我单击build/rebuild按钮时，模糊处理工具会自动打开-这证明我正确地链接/配置了它。

可能的问题是什么？请看下面的截图：

Answer 1

安装Dotfuscator Community Edition后(在本例中为C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\Common7\IDE\Extensions\PreEmptiveSolutions\DotfuscatorCE )，dotfuscator.exe是图形用户界面，dotfuscatorCLI.exe是命令行界面。(专业版的名称和路径有所不同。)

根据你编辑的问题和对评论的回应，你似乎以某种方式用dotfuscator.exe的副本取代了dotfuscatorCLI.exe。当Visual Studio build集成调用dotfuscatorCLI.exe时，它期望运行的是命令行，而不是图形用户界面。

请卸载，然后重新安装Dotfuscator Community Edition：

关闭Visual Studio2017的所有实例。Dotfuscator.

• Click

• 从开始菜单中，打开Visual Studio Installer.

• Under "Visual Studio

• 2017"，选择修改(它可能在More drop-down).

• Select

Scroll选项卡下。

• 向下滚动到代码工具部分并取消选中PreEmptive保护-

Modify复选框。卸载完成后，打开“Modify again.

• Select各个组件”选项卡。向下滚动到“代码工具”部分，然后选中“Dotfuscator.

• Click Protection -

Modify”复选框。安装完成后，打开命令提示符。

• run：cd "C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\Common7\IDE\Extensions\PreEmptiveSolutions\DotfuscatorCE"

• Run：dotfuscator.exe.

• Verify PreEmptive user interface (图形用户界面)显示到命令提示符并运行：dotfuscatorCLI.exe.

• Verify

• PreEmptive

• in

• ，并且图形用户界面不能打开。

然后，假设您已经注册了Community Edition，您应该能够在Visual Studio中运行集成了Dotfuscator的Xamarin构建，并且当您这样做时，图形用户界面应该不会打开。

Answer 2

听起来您可能将集成配置为使用GUI可执行文件，而不是CLI (构建)可执行文件。如果您每次构建Xamarin应用程序时都看到Dotfuscator GUI出现，这可能就是问题所在。

根据您使用的是Dotfuscator Community Edition还是Dotfuscator Professional，可执行文件的名称可能不同。对于CE，请使用dotfuscatorCLI.exe。对于专业版，使用dotfuscator.exe。
