+# Dotnet Core examples
+
+The following examples showcase how to use OrTools. The project solution has examples for both C# and F#.
+
+We recommend that all projects you create target `netcoreapp2.0` as this allows you to compile for various frameworks and keep up-to-date with the latest frameworks.
+
+Wherever you have ortools installed, be sure to reference the `Google.OrTools.dll` from the project file. You will also need to reference the library folder housing native libraries. 
+
+### Linux
+To reference a particular folder on linux, you can either: explicitly set the **LD_LIBRARY_PATH**; or create a new configuration file with the path of the library folder in `/etc/ld.so.conf.d/` and then run `sudo ldconfig`. The former will set the path on a system level so that you don't have to use the environment.
+
+### MacOS
+To reference a particular folder on linux, you can explicitly set the **DYLD_LIBRARY_PATH**
+
+## CSharp/FSharp project examples
+
+By default all the examples are compiled in a console application with the startup object being the **Classname.Main** so that when compiled the entrypoint will be known.
+
+## NetFx/FSharp compiler examples
+
+Should you have another **netfx** you can compile individual file examples. Please see readme in the individual folders for the target language.

+# Examples of using or-tools in C#
+
+This file describes how to use the or-tools .NET binary archive in C# 
+
+## Execution
+
+Running the examples will involve compiling them, then running them. You can run the following command for your target operating system.
+
+For example you can compile and run `csflow.cs`. This assumes you have the archive library in a folder called `bin`.
+
+
+### Windows (32 bit)
+```
+csc /target:exe /out:bin\csflow.exe /platform:x86 /lib:bin /r:Google.OrTools.dll examples\csharp\csflow.cs 
+bin\csflow.exe
+```
+
+### Windows (64 bit)
+```
+csc /target:exe /out:bin/csflow.exe /platform:x64 /lib:bin /r:Google.OrTools.dll  examples\csharp\csflow.cs
+bin\csflow.exe
+```
+
+### Linux (framework 4.6+ via mono must be installed)
+```
+mcs /target:exe /out:bin/csflow.exe /platform:anycpu /lib:bin /r:Google.OrTools.dll examples/csharp/csflow.cs
+mono bin/csflow.exe
+```
+
+### Mac OS X (framework 4.6+ via mono must be installed)
+```
+mcs /target:exe /out:bin/csflow.exe /platform:anycpu /lib:bin /r:Google.OrTools.dll examples/csharp/csflow.cs
+DYLD_FALLBACK_LIBRARY_PATH=lib mono64 bin/csflow.exe
+```
