netstandard 问题。 mono-6.6.0-ubuntu-18

Question

VS Windows 2022 17.1。

我有一个在 Android、iOS、macOS 和 UWP 上运行的 xamarin 应用程序。

现在我按照this描述添加了一个GTK项目

我想创建一个独立的捆绑包。为此，我跑步

mkbundle TimeDateCalculator.gtk.exe --simple -o timedatecalculator --cross mono-6.6.0-ubuntu-18

在窗户上或

mkbundle -o timedatecalculator --simple TimeDateCalculator.gtk.exe --config /etc/mono/config --machine-config /etc/mono/4.5/machine.config

在 wslg 中。

结果是这样的：

ERROR: Unable to load assembly `netstandard' referenced by `/mnt/d/Users/eigil/projects/xamarinProjs/TimeDateCalculator/TimeDateCalculator/TimeDateCalculator.gtk/bin/Release/TimeDateCalculatorDll.dll'

尝试解决我添加的问题

 <Reference Include="netstandard, Version=2.0.0.0, Culture=neutral, processorArchitecture=MSIL">
  <Private>True</Private>
</Reference>

到 .gtk.csproj 文件。

现在

mkbundle TimeDateCalculator.gtk.exe --simple -o timedatecalculator --cross mono-6.6.0-ubuntu-18

给出

Generated timedatecalculator

！

但是当我在 wslg (ubuntu 21.10) 中运行捆绑应用程序时，结果是：

    Unhandled Exception:
System.IO.FileNotFoundException: Could not load file or assembly 'netstandard, Version=2.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51' or one of its dependencies.
File name: 'netstandard, Version=2.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51'
[ERROR] FATAL UNHANDLED EXCEPTION: System.IO.FileNotFoundException: Could not load file or assembly 'netstandard, Version=2.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51' or one of its dependencies.
File name: 'netstandard, Version=2.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51'

我该如何解决这个问题？我尝试将 gtk 项目目标框架从

.NET Framework 4.8

更改为

.NET Framework 4.7

但后来我得到了这个

Answer 1

我知道这是一个super老问题，但我遇到了同样的问题并找到了解决方案，即手动将“netstandard”的外观库添加到 mkbundle 命令中：

mkbundle ..... myApp.exe "$LibPath45/Facades/netstandard.dll"

在我的例子中 LibPath45 是 /usr/local/lib/mono/4.5
