How to load razor class library at runtime (as Plugin) in Blazor wasm (or server) ?

Hamed Vaziri 136

Hi
Is there any way to load razor class library into my existing blazor wasm (or server) application without adding it as reference (load at runtime dynamically)?
I found this link for asp.net core mvc, but the structure of that have different with blazor app.
Thanks in advance ...

To handle all issues, manly dependent assemblies for the assembly being loaded, it can be complicated see: https://github.com/oqtane/oqtane.framework/discussions/1076#discussioncomment-324100

Thanks for reply.
After investigation of oqtane project, I've found the main action which load external assemblies is :
OqtaneServiceCollectionExtensions.LoadAssemblies and then register some services which exists on loaded assemblies.
If i was right, please let me know (& tell me more information about it).
Thanks in advance

Yes that is correct, however there is a lot more code involved. Oqtane works with Blazor WebAssembly and Blazor server so you have to keep that in mind when reading the code. I would suggest downloading the code, setting a breakpoint and step through the process.

It would be way too much to explain here. You may want to watch the videos where Shaun Walker explains it: https://www.youtube.com/results?search_query=Blazor+Oqtane
