Missing assets.js when starting any web project

[codeus-de]

I've just started trying Evergine and really do like the your approach your taking!

One problem immediately arises when I try to run a web project. This is true for "file / new / project" as well as for the included demo projects like DigitalTwin.

All index.html files reference an assets.js file. I can't find this file anywhere and the browser can't either (always getting 404 not found). I assume that because this file is missing the web projects can't be started (stuck at loading screen).

Can you please tell me what to do to get a web app (preferrably Blazor WebAssembly) running?

Hello @codeus-de,

We've detected that one Visual Studio specific version break the web compilation. Try to update Visual Studio to the latest version

I seem to be experiencing this issue on the latest version of Visual Studio. I also can't seem to get it to work when publishing from the command line. The assets.js file never appears in wwwroot, whether in the build or the publish.

@codeus-de were you able to solve your issue?

My mistake! I had another build error that I didn't notice as it was during the emscripten build step.

It looks like it might be an issue with Bullet physics. I removed <PackageReference Include="Evergine.Bullet" Version="2023.3.1.2" /> from my .csproj and everything started working.

Hello, I just installed Evergine and tried to create a web project, however I came across the same problem described above: assets.js is never created, browser cannot find it (404). Removing <PackageReference Include="Evergine.Bullet" Version="2023.9.28.511" /> did not help

I have latest Visual Studio 2022, I tried running from the terminal

Hi @Kanawanagasaki, I think that you miss to install the wasm-tools-net6 workload? In a command line, execute: dotnet workload install wasm-tools-net6

Here you can find more information: https://docs.evergine.com/2023.9.28/manual/platforms/web/index.html

Some times ago, you only need to install the wasm-tools workload, but since recently NET7 broke the backward compatibility in wasm tools, it split the workload for a NET6 specific.

Best regards
