.Net Core Module Install

access_time Updated Mar 27, 2023


  • .NET Core 2.1 or later.
  • Verify you have installed the Signal Sciences agent for your platform (e.g., Linux or Windows). See Agent Installation instructions.


  1. Download the latest SigSci HTTP middleware using one these methods:

  2. Add the SigSci HTTP middleware to your project. Replace <packagePath> with the path to SignalSciences.HttpMiddleware.<version>.nupkg and <sourcePath> with the folder-based package source to which the package will be added:

    nuget add <packagePath> -Source <sourcePath> -Expand
    dotnet add package SignalSciences.HttpMiddleware -s <sourcePath>
  3. Add the following sections to your application’s appsettings.json file:

        "SigsciOptions": {
            "AgentEndPoint": ""
  4. Configure the HTTP request pipeline with Configure:

    Configure(IApplicationBuilder app, IHostingEnvironment env) {
        var sigsciOptions = Configuration.GetSection("SigsciOptions").Get<SigSciOptions>();
  5. Restart the web site service.

Note: Ensure the AgentEndPoint value is set to the same IP and port configured with the Signal Sciences agent’s rpc-address value. See the Windows agent installation documentation for additional information about Windows agent configuration options.
