HtmlFileUploadControldll 'Microsoft.Extensions.PlatformAbstractions error in Infragistics.Web.Mvc.MiddleWare.UploadModuleMiddleware
posted

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.
