PLCnext Technology integrates programming of different languages, and enables users to create real time components in C# using their familiar Microsoft® Visual Studio® as the integrated development environment. For More information please visit our Community.
The CSharpExamples repository is a collection of various examples for PLCnext Technology controllers. It is assumed that the reader has basic knowledge about C# programming in general and has read the User Manual and the PLCnext Technology Quick Start Guide. Each example explains one or more topics. Specific explanations can be found in the ExampleName.md file located next to the ExampleName.cs

Most of the examples in the PLCnext_CSharpExamples folder are ready to build and try with the PLCnext Toolchain C# Extension for Visual Studio. Follow the steps to get started:
- Make sure you have all the required installations.
- Start a new Visual Studio project (only step 1 is needed).
- Copy all files from the
PLCnext_CSharpExamplesfolder to your project folder. - In Visual Studio Solution Explorer enable "Show All Files" (see red square in the picture)
- Select all added files and add them to the project via right click "Include in Project".
- To be able to build, enable unsafe code in the Project --> Properties --> Build and select "Allow unsafe code"
Note: There will be some Warnings and Massages from the Code Analyzer which can be ignored or will be suppressed via the
GlobalSuppressions.csfile.
