我在 Orangepi 板上安装了 SDK（基于 ARM）

tayfur@OrangePi:~$ dotnet --info
.NET Core SDK (reflecting any global.json):
 Version:   3.1.301
 Commit:    7feb845744

Runtime Environment:
 OS Name:     ubuntu
 OS Version:  16.04
 OS Platform: Linux
 RID:         ubuntu.16.04-arm
 Base Path:   /home/orangepi/dotnet/sdk/3.1.301/

Host (useful for support):
  Version: 3.1.5
  Commit:  65cd789777

.NET Core SDKs installed:
  3.1.301 [/home/orangepi/dotnet/sdk]

.NET Core runtimes installed:
  Microsoft.AspNetCore.App 3.1.5 [/home/orangepi/dotnet/shared/Microsoft.AspNetCore.App]
  Microsoft.NETCore.App 3.1.5 [/home/orangepi/dotnet/shared/Microsoft.NETCore.App]

To install additional .NET Core runtimes or SDKs:
  https://aka.ms/dotnet-download

在我使用 vs2019 开发应用程序之后

Windows 窗体应用程序 (.NET Core)

我添加了表格和 bttuon 来打个招呼。

我用“dotnet test1.dll”在电脑上测试了它的工作正常

但它不适用于 orangepiboard（ARM ubuntu 16.4）

错误：

tayfur@OrangePi:~/netcore$ ls
test1.deps.json  test1.exe  test1.runtimeconfig.dev.json
test1.dll        test1.pdb  test1.runtimeconfig.json

tayfur@OrangePi:~/netcore$ dotnet test1.dll

It was not possible to find any compatible framework version
The framework 'Microsoft.WindowsDesktop.App', version '3.1.0' was not found.
  - No frameworks were found.

You can resolve the problem by installing the specified framework and/or SDK.

The specified framework can be found at:
  - https://aka.ms/dotnet-core-applaunch?framework=Microsoft.WindowsDesktop.App&framework_version=3.1.0&arch=arm&rid=ubuntu.16.04-arm
tayfur@OrangePi:~/netcore$

我该如何解决。基本上，我想在 vs2019 上编写一个表单应用程序，并在 orangepi 板上运行。
