 # MiniShell
+A reverse shell for Windows systems that brings some convenience features.
+Among them are:
++ file transfer
++ automatic reconnection attempt on connection loss
++ easy duplication of established shells
++ easy choice between cmd and powershell command interpreter
++ features can be chosen at build time (can be stripped down to a minimal shell without extra features)
+
+
+# Build
++ using Visual Studio 2022
+
+## .NET executable
++ preferably leave target framework at net46 since this should work most Windows 10 and newer system out of the box
+
+### Build relese version
++ smaller than debug
++ debug output disabled (doesn't matter much for regula use)
+```
+MSBuild.exe .\MiniShell.sln /p:Configuration=Release
+```
+### Build debug version
+```
+MSBuild.exe .\MiniShell.sln /p:Configuration=Debug
+```
+
+## Native executable
++ should work on older Windows systems
++ uses the ahead-of-time compilation feature of .NET 7+ (https://learn.microsoft.com/en-us/dotnet/core/deploying/native-aot/?tabs=net7%2Cwindows)
++ binaries are much larger than .NET binaries, but should work on Windows systems without .NET runtime
+
+### Build release version
++ recommended since it saves about half in size
+```
+dotnet publish -r win-x64 -c Release -f net8 -p:PublishAot=true --self-contained
+```
+
+### Build debug version
+```
+dotnet publish -r win-x64 -c Debug -f net8 -p:PublishAot=true --self-contained
+```
