    Cut by the bleeding edge: Has anyone managed to get U15 stood up on Linux?

    Running: Umbraco 15, .NET 9 and Ubuntu/Linux

    I continue to run into the following error on application start:

    Unhandled exception. System.TypeLoadException: Could not load type 'Microsoft.AspNetCore.Builder.IISServerOptions' from assembly 'Microsoft.AspNetCore.Server.IIS, Version=9.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'.

    It seems like the error is getting generated here (Github Source), but no changes were made to this class method between v14 and v15.

    My Ubuntu server has .NET 9 installed:

    % sudo apt install dotnet9

    And I've added UseKestrel to my Program.cs file.

    builder.WebHost.UseKestrel(options => options.AddServerHeader = false);

    Trying to decipher if this is an Umbraco issue, or a .NET 9 issue... I'm leaning toward .NET. Possibly some kind of minor version mismatch... but application has been running just fine locally on MacOS.
