.net 6.x

dotnet workload uninstall maui
dotnet workload uninstall android
dotnet workload uninstall ios
dotnet workload uninstall maccatalyst

 

.net 2.x

step 1.发布网站 Build/publish Windows

dotnet publish
 Nop.Web succeeded (312.3s) → bin/Release/net9.0/publish/

 

dotnet publish -c  release
output
/src/Libraries/Nop.Core/bin/release/net9.0/Nop.Core.dll
dotnet publish -c Release 

src/Libraries/Nop.Core/bin/Release/net9.0/Nop.Core.dll

 

JITBENCH_ASPNET_MANIFEST (powershell) OR

dotnet publish -c Release -f netcoreapp2.1 --manifest %JITBENCH_ASPNET_MANIFEST% (cmd)  

dotnet publish -c Release  

Step 2: Run the app

cd E:\Nopcommerce\MslyAspNetGrandNode40\src\Nop.Web\bin\Release\netcoreapp2.0\publish

dotnet Nop.Web.dll 发布后定位到publish目录使用 dotnet xx.dll 执行应用。

dotnet run -c Release Dotnet run --urls="http://域名:端口号"  如果想设置多个域名，可以使用分号分隔。

  Step 3：change port 5000 to other  

2. 发布控制台程序为exe 文件 net core 2.0程序默认生成的是一个dll，需要通过dotnet命令来执行他。

dotnet ConsoleApp1.dll 生成带exe的命令则是：--runtime <rid>    

 dotnet build --runtime win-x64

copy D:\Temp\ConsoleApp1\ConsoleApp1\bin\Release\netcoreapp2.1\win-x64\publish下所有文件到另外机器 CMD run ConsoleApp1.exe    

 

 

dotnet publish -c Release -r win-x64 --self-contained

 

.Net 6.x     2021/11/12

dotnet run -c Release -f net48 -filter "**" --runtimes net48 net5.0 net6.0
