Error when I try to run a web app that is based on .NET 3.1

I have a web app that is based on .NET 3.1. I attempted to use Mono, but it returned an error that reads:

Can't find custom attr constructor image: /usr/home/ninjagpt/e5/XXXXXX.dll mtoken: 0x0a00000a due to: Could not load file or assembly 'Microsoft.AspNetCore.Mvc.Core, Version=3.1.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60' or one of its dependencies.
Could not load signature of XXXXXX.Program:CreateHostBuilder due to: Could not load file or assembly 'Microsoft.Extensions.Hosting.Abstractions, Version=3.1.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60' or one of its dependencies.

Afterward, I found a version of .NET Core 3.1.103 for FreeBSD available at this link, and I downloaded it. However, when I tried to use it to run my app, it returned the following error:

Failed to create CoreCLR, HRESULT: 0x8007000E

I also tried executing the following command:

cpuset -l 0 ~/dotnet/dotnet ~/XX/XXXXXX.dll

But it returned another error:

Unhandled exception. System.IO.IOException: Too many open files

Could you please help me figure out how to run this on Serv00? I appreciate your assistance. Thank you.

ninjagpt Dotnet 3 is ancient and wasn't supported officially. Now you can use builds based on official port like the user here: https://forum.serv00.com/d/326-access-to-the-path-etcsslcerts-is-denied-using-dotnet-8

cloverdev It's not true - you can run your own applications, C# is nothing special and now you can use global installation of Mono (if your app is built for versions supported by Mono) or you can use your own dotnet packages/compilation. Soon will be possible to use a global installation of dotnet (still some bugs cause problems with installation).

It's really hard to make a list of everything that we support, sometimes you need to check it by yourself 😉

cloverdev

We are not allowed to install anything that requires super-user permissions.
This post also states that C# isn't installed.

cloverdev Actually, I managed to download Go 1.22 from this link, and it worked when I used its absolute path to run the go build command. I'm thinking, perhaps we could request for the installation of these packages?
