Blazor WebAssembly Template Bug #1766

hillin created 3 years ago

ABP Framework version: v4.4.0
UI type: Blazor WebAssembly
DB provider: EF Core
Tiered (MVC) or Identity Server Separated (Angular): no

New projects created with abp suite Blazor WebAssembly template does not compile:

C:\Program Files\dotnet\sdk\5.0.302\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.Sdk.FrameworkReferenceResolution.targets(415,5): error NETSDK1112: The runtime pack for Microsoft.NETCore.App.Runtime.browser-wasm was not downloaded. Try running a NuGet restore with the RuntimeIdentifier 'browser-wasm'.

Chaning the blazor project file as follows can make it compile.

<Project Sdk="Microsoft.NET.Sdk.Web">
  <PropertyGroup>
    <TargetFramework>net5.0</TargetFramework>
    <UseBlazorWebAssembly>true</UseBlazorWebAssembly>
  </PropertyGroup>
</Project>

WIth the problem above fixed, the app can run now, but the blazor website does not work because the file /_framework/blazor.boot.json cannot be found (404). It seems this file was not generated at all at build time.

The problem is caused by the mismatch between the version of the Microsoft.AspNetCore.Components.WebAssembly and Microsoft.AspNetCore.Components.WebAssembly.DevServer packages referenced by the blazor project, and the version of the .NET SDK. In the ABP template, these packages are referenced with a wildcard version (5.0.*), so the latest matching version (5.0.9) was restored; but I didn't have .NET SDK 5.0.9 installed (my latest was 5.0.3). Installing .NET SDK 5.0.9 has fixed the problem.
