[API Proposal]: Assembly.LoadFrom(myassembly.cs)

[lakani]

Background and motivation

It would be nice to load Assembly from just a .cs file, this would easily allow new kind of add-ons to be developed,

Assembly.LoadFrom(myassembly.cs)

API Proposal

Assembly.LoadFrom(myassembly.cs)

API Usage

using System;
using System.Reflection;

// Assume you have an interface defined in a shared project
public interface IPlugin
{
void Run();
}

// In your main application code:
string assemblyPath = "C:\path\to\MyLibrary.dll";
string fullClassName = "MyNamespace.MyClass"; // Full name including namespace

try
{
// Load the assembly from the file path
Assembly assembly = Assembly.LoadFrom(assemblyPath);

// Get the Type information for the specific class
Type type = assembly.GetType(fullClassName);

if (type != null && typeof(IPlugin).IsAssignableFrom(type))
{
    // Create an instance of the class
    object instance = Activator.CreateInstance(type);

    // Cast it to the shared interface and use it
    IPlugin plugin = (IPlugin)instance;
    plugin.Run();
}
else
{
    Console.WriteLine($"Class {fullClassName} not found or does not implement IPlugin.");
}

}
catch (Exception ex)
{
Console.WriteLine($"Error loading assembly or creating instance: {ex.Message}");
}

This is not possible. C# compiler isn't a included in the published runtime. Additionally, the required references may not be available either.

This should be done via the C# compiler package Microsoft.CodeAnalysis.CSharp.Scripting. Closing.
