This section describes how to set up a .NET Framework native client development environment using C# and CMake.

Prerequisites

This walkthrough assumes that certain components are in place:

The Geode Native Client libraries. Install the Native Client as described in Getting Started with the Native Library. Follow the ease-of-use recommendations by installing the Native Client in C:\Program Files\nativeclient.
The CMake tool suite. Download and install CMake, following the instructions on cmake.org.
Geode: Install and configure Geode. See the Geode User’s Guide for instructions and system requirements.
Visual Studio 2015 or higher and .NET Framework 4.5.2.

To develop a Native Client application using .NET Framework and CMake:

Create a project directory structure
Populate the project directories with C# source code
Configure the CMake build environment
Run CMake to configure your application
Build and run your application using Visual Studio

Setting up Directories and Sources

Create a project directory structure. In this example, the project is called MyProject. The directory structure provides a place for your application source files and a cmake modules directory for project-specific CMake files:
```
MyProject\
  cmake\
    FindGeodeNative.cmake
  CMakeLists.txt
  Program.cs
```
Change directory to MyProject and create your application sources. In this example, we have one source file, Program.cs.

Configuring CMake

Copy the FindGeodeNative.cmake script from one of the Native Client examples to the cmake subdirectory.
Create CMakeLists.txt. Copy the file from an example, if you like, as a starting point. The CMakeLists.txt file should contain the following CMake instructions:

CMake minimum version
```
cmake_minimum_required(VERSION 3.10)
```
Your project name and language
```
project(MyProject LANGUAGES CSharp)
```
Path to the CMake modules directory where the FindGeodeNative.cmake script is located and an instruction telling CMake to use it:
```
set(CMAKE_MODULE_PATH ${PROJECT_SOURCE_DIR}/cmake)
find_package(GeodeNative REQUIRED COMPONENTS dotnet)
```

The compilation target and the source(s) to be compiled

add_executable(MyProject Program.cs)

target_link_libraries(MyProject
  PUBLIC
    GeodeNative::dotnet)

set_target_properties(MyProject PROPERTIES
    VS_DOTNET_TARGET_FRAMEWORK_VERSION "v4.5.2"
    VS_DOTNET_REFERENCES "System;{GemFireNative_DOTNET_LIBRARY})

Combined, the above elements comprise the following CMakeLists.txt:

# CMakeLists.txt for .NET Framework Native Client App
cmake_minimum_required(VERSION 3.10)

project(MyProject LANGUAGES CSharp)

set(CMAKE_MODULE_PATH ${PROJECT_SOURCE_DIR}/cmake)

find_package(GeodeNative REQUIRED COMPONENTS dotnet)

add_executable(MyProject Program.cs)

target_link_libraries(MyProject
  PUBLIC
    GeodeNative::dotnet)

set_target_properties(MyProject PROPERTIES
    VS_DOTNET_TARGET_FRAMEWORK_VERSION "v4.5.2"
    VS_DOTNET_REFERENCES "System;${GemFireNative_DOTNET_LIBRARY}")

Configuring the App

Create a build directory and set it as your current directory:
```
$ mkdir build
$ cd build
```
Run CMake to configure the build:
```
$ cmake ..
```

This creates a Visual Studio solution for your .NET Framework application. For example, MyProject.sln.

Building and Running the App

Open the solution file in Visual Studio and build the project.
