dynamic lazy loading in blazor

Question

In a Blazor wasm project I would like to dynamically load a second project without knowing the project at compile time (.Net5). Therefore the normal 'lazy loading' does not work for me. Are there libraries for such purposes? Or an example solution

Does this answer your question? [Can I load a .NET assembly at runtime and instantiate a type knowing only the name?](https://stackoverflow.com/questions/465488/can-i-load-a-net-assembly-at-runtime-and-instantiate-a-type-knowing-only-the-na) — gunr2171, Apr 01 '21 at 13:46
Hey, it seems like your "Seeking recommendations for books, tools, **software libraries**, and more" (emphasis mine), which is a close reason on Stack Overflow — MindSwipe, Apr 01 '21 at 13:47

I am also looking for this capability. The static compile time referance in .net 6 is not great.

Have a look at oqtane they were doing some work in lazy loading at runtime back in .net 3.1, unfortunatly it seems that they went more into a nuget direction instead of just dll's https://docs.oqtane.org/index.html https://github.com/oqtane/oqtane.framework/discussions/1076

A little late here but in NET 6 you can do it, I did a Manager where you can look at

https://github.com/elgransan/BlazorPluginComponents

Some example code

        var componentPackage = "RazorClassLibrary2";
        var component = "Component2";
        var stream = await Http.GetStreamAsync($"{MyNavigationManager.BaseUri}/{componentPackage}/{componentPackage}.dll");
        var assembly = AssemblyLoadContext.Default.LoadFromStream(stream);
        componentType = assembly.GetType(componentPackage + "." + component);
        await DOMinterop.IncludeLink(componentPackage, $"/{componentPackage}/{componentPackage}.styles.css");
