How to get a Type by string without specifying the assembly name, if it's among loaded asms

Okay, it's been forever since I had to do this in C#, but I need to get a Type by name without having to specify the assembly name, if it is among the currently loaded assemblies for the app domain. What's the best way to do this. Basically I want it to do what Type.GetType() does but a bit more permissive in that it searches all loaded assemblies instead of just the calling assembly when it comes to nonqualified names

Blazor WASM + prerender - handling forms on client & server

I'm trying out Blazor WASM + prerender and I noticed that form submission is handled by either server or WASM C#, depending on whether the latter is loaded (yet). Given that some logic must run on the server (e.g. DB access), what's the standard approach to "marshalling" the invocation to the server? I definitely prefer to have WASM handle the initial submission for interactive validation, status display, etc...

Specifying 4xx Details

I have a POST request that may cause a duplicate entry if it were to execute. As a response, I send back 409 Conflict to make clear what happened. However, I have some trouble adding some detail to explain what exactly happened.

IDisposable ownership semantics

This is primarily a question regarding whether or not C# has introduced any sort of syntactic sugar or support for a "nicer" way of expressing transfer of ownership. For the purposes of this question, nullable types is fully enabled and static analysis that will issue CA2000 as an error is also turned on. Consider a method that returns a type that implements IDisposable and needs to either return it, or ensure it gets Dispose'd if an exception occurs - Currently I'd write something like this:...
