Install VisualStudio (Windows only) or the VS Code development environment and setup a C# project.
You can test the development setup by creating a new folder and open a terminal in that folder with the console commands:
dotnet new console
dotnet restore
dotnet build
dotnet run
code .
In the C# project, install the SharpGfx.OpenGL.OpenTK nuget package into your project via the package manager.
Alternatively you can use the cosole command:
dotnet add package SharpGfx.OpenGL.OpenTK
Rebuild your project.
SharpGfx Test Program
The following code demonstrates a complete hello triangle program producing a plain triange that can be viewed in 3D. This code serves as function test. Also, you get an idea how it looks like.// It is sufficient to reference package SharpGfx.OpenTK, the other needed packages will be included automatically
