Simple tools for experimenting with network communications written primarily for Windows in .NET. To get the latest working build head to https://dl.bintray.com/tewarid/net-tools/.

To build all the tools, clone the repository, and initialize submodules

git clone https://github.com/tewarid/net-tools.git
cd net-tools
git submodule update --init --recursive

You can open the solution file NeTools.sln using Visual Studio 2017 and build.

To build from the command line, open Developer Command Prompt for VS 2017, change to the net-tools directory, and run

nuget restore NetTools.sln
msbuild NeTools.sln

You may have to download nuget from nuget.org.

A solution file is available for building some of the tools for Linux using Mono.

Use the msbuild version supplied by Mono to build

msbuild NetTools.Mono.sln

A solution file is available to build some of the tools for Windows using .NET Core

dotnet build NetTools.NetCore.sln

You can also use Visual Studio 2019 Preview to build.
