At runtime a lot of DLL's are being fetched... #2

Hi Santiago,

your repo worked like a charm, but my own implementation did not. It's quite a complicated and large old MVC application, where a small part is replaced by a wasm component.
As far as I can see everything is done like your example, but on running the mvc app I get loads of Internal Server errors in the Developer Tool's Network tab. They are all errors concerning fetches of dll's. I checked your examples and your example doesn't fetch any dll's (as it shouldn't indeed).
Do you have any idea why my app is fetching all those dll's?
Thanks in advance!

Hi, all those dll must be downloaded from the server for sure, because blazor wasm runs on the client and it need its.

Did you add on your web.config this rules:

Or can you show me the real error (it says error 500 server error)

Hi, thanks for your quick reply. I did add those web.config rules, I checked it again … The error in the Network tab of Chrome: The errors in the Console output in VS2022: Uncaught TypeError TypeError: Failed to fetch at loadResourceWithoutCaching (D:\Source\Repos\GOconnectIT\Click-App\KlicApp\KlicApp.Web\_framework\blazor.webassembly.js:1:52251) at loadResourceWithCaching (D:\Source\Repos\GOconnectIT\Click-App\KlicApp\KlicApp.Web\_framework\blazor.webassembly.js:1:51982)
