OPC-UA-OOI-webapp

Web application built using ASP.NET Core 3.0 with Blazor Server as an example usage of OPC-UA PubSub Standard

Application depends on open-source NuGet packages developed by Mariusz Postół on github.

Goals

• Implementing OPC-UA Part 14 PubSub protocol for m2m communication
• Designing application architecture based on dependency injection
• Handling and displaying asynchronous data from IoT machines
• Designing graphical interface which changes based on the type of the data received

Build steps

• Download and install ASP.Net Core 3.0.0
• Clone or download this repository
• Either:
  • Use dotnet CLI:
    • Navigate to ReferenceWebApplication project's directory (project, not solution)
    • Open command line and run dotnet run
    • Open a browser and navigate to https://localhost:5001 (unless this port was already taken)
  • Use Visual Studio 2019 (ASP.Net Core 3.0.0 won't work on earlier versions, reference):
    • Make sure you have installed necessary Visual Studio tools for developing ASP.Net Applications (You can use Visual Studio Installer to easily install those tools)
    • Open the ReferenceWebApplication solution
    • Choose IIS Express in the dropdown menu in the build toolbar
    • Build and run - this should open a browser with the right URL
