Click Open Project in CMake-gui - this will open Visual Studio.

Build solution in visual studio

If you want to install the library in the system:

Open a Command Prompt in the libiio folder and copy all the .dll files in C:\Windows\System32 .
Open a Command Prompt in the build folder and copy libm2k.dll in C:\Windows\System32 .
In the build folder run pip install wheel and python setup.py bdist_wheel in order to build and install the Python Bindings.

C# bindings

The C# bindings are built by default. In order to disable them, set ENABLE_CSHARP=OFF in the CMake configuration.
In order to use the C# bindings, you need to copy the following dlls in your build folder: libm2k-sharp.dll and libm2k-sharp-cxx-wrap.dll . These can be found in C:\Program Files\Common Files\libm2k if you installed libm2k using the system installer. Otherwise, you can download the latest archive from appveyor: Appveyor artifacts and get the dlls from there.
Add libm2k-sharp.dll as a reference in your project.
Check the examples from the source code.
