是否可以在 .net core 2.2 中发布单个 EXE 文件

Question

基于 .net core 2.2 构建的项目。想要发布单个 EXE 文件。无法发布为单个 EXE 文件。

我在包控制台中尝试了以下命令

dotnet publish -r win-x64 -c Release /p:PublishSingleFile=true

    Restore completed in 995.93 ms for C:\Demo\New   
    folder\BHHS\Importer\Importer.csproj.
    You are using a preview version of .NET Core. See: https://aka.ms/dotnet-core-preview
     Importer -> C:\Demo\New folder\BHHS\Importer\bin\Release\netcoreapp2.2\win-x64\Importer.dll

没有。这仅适用于 .NET Core 3.0 及更高版本。在此处查看详细信息 - https://devblogs.microsoft.com/dotnet/announcing-net-core-3-0-preview-5/
