Title: Unable to resolve ‘Microsoft.NETCore.App.Runtime.Mono.browser-wasm’ for ‘net8.0’ in Blazor project

Body:

Hello everyone,

I’m working on a Blazor project and I encountered an issue when trying to restore NuGet packages. Here is the error message I’m getting:

Severity    Code    Description    Project    File    Line    Suppression State
Error (active)    NU1100    Unable to resolve 'Microsoft.NETCore.App.Runtime.Mono.browser-wasm (= 8.0.6)' for 'net8.0'. PackageSourceMapping is enabled, the following source(s) were not considered: C:Program Filesdotnetlibrary-packs, Microsoft Visual Studio Offline Packages, nuget.org.    Imc    C:MyBlazorAppsIMCsrcImc.csproj    1

I’ve checked the following:

  • Package source settings in Visual Studio
  • Internet connection
  • Version compatibility

Here’s the relevant part of my .csproj file:

<Project Sdk="Microsoft.NET.Sdk.BlazorWebAssembly">

  <PropertyGroup>
    <TargetFramework>net8.0</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.NETCore.App.Runtime.Mono.browser-wasm" Version="8.0.6" />
  </ItemGroup>

</Project>

Does anyone know how to resolve this issue? Any help would be greatly appreciated.

Thanks in advance!

I checked my package sources in Visual Studio to ensure they include nuget.org, verified my internet connection, and confirmed the version compatibility of the package. I expected the package to be resolved and restored without any issues. However, the error persists and the package cannot be resolved.

    I managed to resolve the issue by removing the NuGet packages and then adding them again. Here are the steps I followed:

    1. Remove the problematic package:

      • Open the NuGet Package Manager in Visual Studio.
      • Locate the Microsoft.NETCore.App.Runtime.Mono.browser-wasm package.
      • Uninstall the package.

    2. Clear the NuGet cache:

      • Open the command prompt.
      • Run the following command to clear the NuGet cache: 
        nuget locals all -clear

    3. Re-add the package:

      • Go back to the NuGet Package Manager in Visual Studio.
      • Search for Microsoft.NETCore.App.Runtime.Mono.browser-wasm.
      • Install the package again.

    4. Restore the NuGet packages:

      • Right-click on the solution in Visual Studio.
      • Select Restore NuGet Packages.

    After following these steps, the package was successfully resolved and restored. I hope this helps anyone facing a similar issue!

    I used dotnet add package command to install this package but can’t install too. From looking at the README from nuget org,it notes:

    Internal implementation package not meant for direct consumption. Please do not reference directly.

    This doc notes FrameworkReference ,
    to reference ASP.NET Core, try to add the following element to your project file:

     <FrameworkReference Include="Microsoft.AspNetCore.App" />

    Hope it can help you.
