Quick test on how to dip into C/C++ from C# using your own shared C++ libraries

# Building
|
|
Building and testing is quite quick and only involves several steps. Before proceeding, it should be noted that this quick test targets Linux. This makes a difference because in Linux C++ shared libraries have a *.so file extension compared to Windows having a *.dll file extension. The ``Program.cs`` file is looking for a shared library with an extension ending is *.so. As is this test will not work on Windows without some modifications.

### Required
|
|
* Linux
|
|
* .NET Core 3.1
|
|
* GCC >= 7 or clang >= 7

## Building C++ library
|
|
1. Change into the C++ Libs directory and create a build directory
|
|
```Bash
|
|
cd Libs; mkdir build
|
|
```
|
|
2. Build the C++ library
|
|
```Bash
|
|
cd build; cmake -DCMAKE_BUILD_TYPE=DEBUG ..; make
|
|
```
|
|
3. Copy the library to the root of the project
|
|
```Bash
|
|
cp libTestExample.so ../../
|
|
```
|
|
|
|
## Building .NET console software
|
|
1. Ensure that you are in the root of the project. Then build the software
|
|
```Bash
|
|
dotnet build
|
|
```
|
|
2. Copy the C++ library to where the executable is build
|
|
```Bash
|
|
cp libTestExample.so bin/Debug/netcoreapp3.1/
|
|
```
|
|
3. Run the software
|
|
```Bash
|
|
dotnet run
|
|
```
|
|
4. The .NET code is calling a function from the C++ library that was built. The result is the sum of two integers
