我是Blazor的新手，我想使用一个具有NLog 4.6.2作为依赖项的库。我不是在尝试使用NLog记录日志，而是试图利用该库。为了找出问题，我在.csproj文件中添加了NLog 4.6.2作为依赖项
<PackageReference Include="NLog" Version="4.6.2" />
构建应用程序时，出现以下错误：

有人可以为我指出正确的方向，以帮助我使其正常工作。我想要实现的一切就是NLog依赖项允许我构建和运行该应用程序...暂时不尝试登录。
答案 0 :(得分：2)
如果检查输出，则会发现此操作失败，因为NLog取决于System.Threading.Thread.CurrentPrincipal。
Blazor / Mono不支持线程（因此无论如何它都将抛出NotImplemented），但是Mono.Wasm也被严重修剪，因此您现在会收到此Linker错误。
我想利用具有NLog 4.6.2作为依赖项的库。
那是不幸的。明智的选择是，库不应具有如此强的依赖性。但这对您没有帮助。
我看到的唯一可行的解决方案是使用Blazor服务器端。或更改或替换该库。
