描述

I've just upgraded my project to .NET 7 and seen that it results in an error (when running):

```
Error setting value to option 'u, url': Check if Option or Value attribute values are set properly for the given type.
Error setting value to option 't, threads': Check if Option or Value attribute values are set properly for the given type.
etc..
```

https://github.com/KoalaBear84/OpenDirectoryDownloader/

If I build it with the following it fails (when running):
```
dotnet publish OpenDirectoryDownloader --configuration Release --framework net7.0 --runtime win-x64 -p:PublishTrimmed=true
```

If I remove the `-p:PublishTrimmed=true` it works. This tells me it could be because of the trimming that will trim something that is important for this library.

Also tried with `-p:TrimMode=Link` and `-p:TrimMode=CopyUsed`, but it doesn't make a difference, but found out that `-p:TrimMode=partial` (Only worked with a lowercase p here) does, as it restores the behaviour of .NET 6.

Maybe this can be resolved at the library side, but I don't have experience with that.

It would be nice if it can be solved, as more users will try/upgrade to .NET 7. Until then this issue will be helpful for everyone looking for a quick workaround.

研究方向

使用 .NET 7 和提供的 dotnet publish 命令重現該故障,然後將其與停用 trimming 以及 TrimMode=partial 的情況進行比較。閱讀連結的 trimming 指南,並檢查該程式庫如何處理會產生錯誤的選項。當啟用 trimming 的發佈能夠執行且不再出現設定選項時回報的錯誤,同時保留正常的命令列行為時,即視為完成。
