Error System.BadImageFormatException service fabric

Question

Problem

I am building service fabric application. When I create a Project and run it its working fine. but when I inject a service in the Api controller it gives me this error I tried to resolved it but not succeeded yet.

Error

System.BadImageFormatException Could not load file or assembly 'dotnet-aspnet-codegenerator-design' or one of its dependencies. An attempt was made to load a program with an incorrect format.

I add the service

protected override IEnumerable<ServiceInstanceListener> CreateServiceInstanceListeners()
        {
            return new ServiceInstanceListener[]
            {
                new ServiceInstanceListener(serviceContext =>
                    new KestrelCommunicationListener(serviceContext, "ServiceEndpoint", (url, listener) =>
                    {
                        ServiceEventSource.Current.ServiceMessage(serviceContext, $"Starting Kestrel on {url}");

                        return new WebHostBuilder()
                                    .UseKestrel()
                                    .ConfigureServices(
                                        services => services
                                            .AddSingleton<StatelessServiceContext>(serviceContext)
                                            .AddScoped(typeof(ISendMessage), typeof(SendMessage))
                                            )
                                    .UseContentRoot(Directory.GetCurrentDirectory())
                                    .UseStartup<Startup>()
                                    .UseServiceFabricIntegration(listener, ServiceFabricIntegrationOptions.None)
                                    .UseUrls(url)
                                    .Build();
                    }))
            };
        }

Answer 1

It is likely that your service or any of their dependencies is targeting a x86 platform.

To fix that, you have to force your service running on x64 and/or replace any x86 dependencies for x64.

If your are running dotnet-core, make sure the x64 tools are installed as well.

You might also try removing the reference to Microsoft.VisualStudio.Web.CodeGeneration.Design from your project as mentioned here

Answer 2

This was an issue we faced sometime ago, It comes when you try to add asp.net core controller. For some reason visual studio adds the reference to "Microsoft.VisualStudio.Web.CodeGeneration.Design".

My sugegstion would be to remove the reference and also not add controller using the Project->Add->Controller.

Just add a basic code file and copy the content from an earlier controller.

Answer 3

Add more binaries for the package, and do AnyCPU for the platform target.

<PackageId>Microsoft.VisualStudio.Web.CodeGeneration.Design</PackageId>
 <RuntimeIdentifier Condition=" '$(TargetFramework)' != 'netcoreapp2.0' ">win7-x86</RuntimeIdentifier>
 <RuntimeIdentifier Condition=" '$(TargetFramework)' != 'netcoreapp2.0' ">win7-x64</RuntimeIdentifier>
