✅ Error when including a project reference in a Blazor WASM project

I'm getting an error There was no runtime pack for Microsoft.AspNetCore.App available for the specified RuntimeIdentifier 'browser-wasm'. only when including a ProjectReference to another project in my solution in a Blazor WASM project. Both projects are targeting net7.0. Do I have to do something special to get the project reference to work properly with WASM or something?

Did you miss an installer workload maybe? Complete guess...

installer workload? The entire csproj is this

Things you select in the installer

What installer?

Studio

Visual Studio? Well, I'm primarily using Rider, but I'm getting that error even when using dotnet build

It looks like a missing runtime

ThinkerOP•2y ago

Hmm, odd since it works when I don't have the project reference I have the Microsoft.AspNetCore.App 7.0.2 runtime installed, although perhaps I do need the WASM runtime?

Asp project might just not be compatible with blazor runtime. There are some stack overflow threads on it. Didn't try to hard to understand 😅

ThinkerOP•2y ago

Well... I added <UseBlazorWebAssembly>true</UseBlazorWebAssembly> and changed the SDK to Microsoft.NET.Sdk.Web instead of Microsoft.NET.Sdk.BlazorWebAssembly now it builds ¯\_(ツ)_/¯ Except now the website just gets stuck at loading with a warning that it failed to load _framework/blazor.webassembly.js So the issue is probably that the other project is not compatible with Blazor WASM, right? How would I make it compatible?

yes Problem solved, issue was that the project has a reference to Microsoft.AspNetCore.App which caused it to not work.
