.NET 5发布成单个exe文件,需要使用参数：

p:IncludeNativeLibrariesForSelfExtract=true

使用命令：

dotnet publish -c Release -o publish -p:PublishReadyToRun=true -p:PublishSingleFile=true -p:PublishTrimmed=true --self-contained true -p:IncludeNativeLibrariesForSelfExtract=true

或者.csproj文件中<PropertyGroup>实现：

<PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net5.0</TargetFramework>
    <PublishSingleFile>true</PublishSingleFile>
    <RuntimeIdentifier>win-x64</RuntimeIdentifier>
    <PlatformTarget>x64</PlatformTarget>
   <IncludeNativeLibrariesForSelfExtract>true</IncludeNativeLibrariesForSelfExtract>
</PropertyGroup>
