Hi,
To integrate infragistics fileupload control to the DotnetCore web application
we registered the required middleware in the project statrtup.cs file as below:
app.UseUploadModuleMiddleware();
But when application deployed into the IIS sever, we are getting the below errors when the application is started:
Application startup exception: System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.Extensions.PlatformAbstractions, Version=1.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'. The system cannot find the file specified.
File name: 'Microsoft.Extensions.PlatformAbstractions, Version=1.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60 at Infragistics.Web.Mvc.MiddleWare.UploadModuleMiddleware..ctor(RequestDelegate next, IOptions`1 appSettings)
Application server having the dotnet core version 2.1.403.
Please advice how to fix this issue.
Hello adil,
You can check the following help topics about Configuring the igUpload Middleware for file upload handling and Adding Controls to an MVC Project.
It will help if you can provide a small, isolated sample application that demonstrates the behavior you are seeing. Please specify which version of the product you are using as well.

Thank for Response.
Here i am attaching isolated sample.
we are using Infragistics.Web.AspNetCore 6.18.1.59.
We are using VisularStudio Dotnet Core 2.1.201
Please let me know incase of any other information required.
Kindly help regarding this issue. This blocking our application deployment into server.
Since Sample application is exceeding the attachment limit here i am Copying the Application Startup.cs code
Thanks
using Infragistics.Web.Mvc;using Microsoft.AspNetCore.Builder;using Microsoft.AspNetCore.Hosting;using Microsoft.Extensions.DependencyInjection;namespace InfraSample{ public class Startup { // This method gets called by the runtime. Use this method to add services to the container. // For more information on how to configure your application, visit go.microsoft.com/.../ public void ConfigureServices(IServiceCollection services) { services.AddMvc(); }
// This method gets called by the runtime. Use this method to configure the HTTP request pipeline. public void Configure(IApplicationBuilder app, IHostingEnvironment env) { if (env.IsDevelopment()) { app.UseDeveloperExceptionPage(); }
app.UseUploadModuleMiddleware(); app.UseUploadHandlerMiddleware();
app.UseMvc(routes => { routes.MapRoute( name: "default", template: "{controller=Home}/{action=Index}/{id?}"); });
//app.Run(async (context) => //{ // await context.Response.WriteAsync("Hello World!"); //}); } }}
I have created a test application using Infragistics.Web.AspNetCore 6.18.1.59 and added the code you sent but I did not reproduce the errors that occur at your side.
I have attached the sample project I used to test this. Please test this project on your PC; whether or not it works correctly may help indicate the nature of this problem.
Or, if this sample project is not an accurate demonstration of what you're trying to do, please feel free to modify it and send it back, or send a small sample project of your own if you have one.
Delete the bin and obj folders before compressing the project.
Please let me know if I can provide any further assistance.
