Hosting ASP.NET Core self-contain web application on Raspberry Pi

Sep 3 2024 4:46 AM

Hi All,

I have an issue with hosting a self-contained ASP.NET Core web application on Raspberry Pi. When I try to run the application I get this error:

Unhandled exception. System.TypeLoadException: Could not load type 'Microsoft.AspNetCore.Mvc.ApplicationParts.ConsolidatedAssemblyApplicationPartFactory' from assembly 'Microsoft.AspNetCore.Mvc.Razor, Version=8.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'.
   at System.Reflection.RuntimeAssembly.GetTypeCore(String, ReadOnlySpan`1, Boolean, Boolean)
   at System.Reflection.TypeNameParser.GetType(String, ReadOnlySpan`1, String)
   at System.Reflection.TypeNameParser.NamespaceTypeName.ResolveType(TypeNameParser&, String)
   at System.Reflection.TypeNameParser.Parse()
   at System.Reflection.TypeNameParser.GetType(String, Func`2, Func`4, Assembly, Boolean , Boolean , Boolean )

   at Microsoft.Extensions.DependencyInjection.MvcServiceCollectionExtensions.AddRazorPages(IServiceCollection)
   at Program.<Main>$(String[]) in C:\Users\mihas\source\repos\HelloWorld\Program.cs:line 4
Aborted

In my application on line 4 there is a code:

// Add services to the container.
builder.Services.AddRazorPages();

I don't understand. If the application is self-contained it should work regardless of the runtime being installed or not on the device which is going to run the application. Does someone know what I'm missing?
