    Download the installer, ComponentOneControlPanel.exe from MESCIUS's website. Follow the steps through the installation wizard to install the ASP.NET DLLs and templates for Web API Edition, its dependency DLLs, stylesheets and scripts.

    Web API services are provided as Visual Studio template, which is available after installation of Web API Edition. Once you create Web API service application using the ComponentOne template on Visual Studio, the template adds the references C1.Web.API.dll, C1.C1Excel.dll, and other related assemblies to your service project.

    Note: It is advisable that you either log off or restart your Windows 10 machine once you have installed the Web API Edition, and then create the service application, so that the required Environment Variables are set. However, if you install the Web API Edition in Windows 10 followed by creating the service application, the required Environment Variables are not set.


    Samples for the product are installed in the ComponentOne samples folder by default.

    Documents\ComponentOne Samples\Web Api

    Note: In case you get any missing assembly errors while running the sample, you need to add the required references from MESCIUS NuGet source.

    To Add Web API Libraries from NuGet
