I’ve created a DotVVM Core 2.0 project using Visual Studio and I have activated a trial version of Business Pack that I have added into that project from the private feed. I have registered the Business Pack in DotvvmStartup.cs in ConfigureServices. I don’t see bp controls in IntelliSense and when I try to run web app with the bp controls I get an error that tagprefix was not registered.

I use latest version of Visual Studio 2017 Community and latest versions of DotVVM and Business Pack. Thanks for any advice.

Perhaps you won't call method DotvvmStartup.ConfigureServices. It is cause by "bug" in VS2017 extension template (v2.0.118.0 and below) and dotnet CLI template (dotvvm.templates.2.0.3).

Please check Startup.ConfigureServices.

  public void ConfigureServices(IServiceCollection services)
  {
      ...
      services.AddDotVVM(); //this line is incorrect
  }

You should replace services.AddDotVVM() with services.AddDotVVM<DotvvmStartup>(); https://github.com/riganti/dotvvm/blob/master/src/DotVVM.Framework.Hosting.AspNetCore/ServiceCollectionExtensions.cs#L17

This create instance of DotvvmStartup and call method DotvvmStartup.ConfigureServices.
DotvvmStartup object is created 2 times (services.AddDotVVM<DotvvmStartup>() and app.UseDotVVM<DotvvmStartup>(env.ContentRootPath)).
