c# - Blazor [WASM] System.TypeLoadException : Could not resolve type with token 0100001a

Question

我收到此错误:enter code here System.TypeLoadException: 无法从 typeref 解析带有标记 0100001a 的类型(程序集“System.Runtime，版本=4.2.2.0，Culture=neutral，PublicKeyToken=b03f5f7f11d50a3a”中的预期类“System.Threading.Tasks.Task”)

当我切换到:

<TargetFramework>netcoreapp3.1</TargetFramework> 

或者

<TargetFramework>netcoreapp5.0</TargetFramework>

来自 netstandard2.1

我的包裹是:

<PackageReference Include="Blazored.LocalStorage" Version="2.1.5" />
        <PackageReference Include="Blazorise" Version="0.9.0.2" />
        <PackageReference Include="Blazorise.Bulma" Version="0.9.0.2" />
        <PackageReference Include="Blazorise.Components" Version="0.9.0.2" />

        <PackageReference Include="System.Net.Http.Json" Version="5.0.0-preview.4.20251.6" />

        <PackageReference Include="Toolbelt.Blazor.I18nText" Version="9.0.1.1" />
        <PackageReference Include="Toolbelt.Blazor.SpeechRecognition" Version="0.0.4.6-alpha" />
        <PackageReference Include="Toolbelt.Blazor.SpeechSynthesis" Version="8.0.0" />

有什么想法可以解决这个问题吗？

附:我很惊讶它在像这里这样的样本中正常工作: https://channel9.msdn.com/Events/Build/2020/BOD104

我想，这个问题已经在这里得到了回答:

Blazor WebAssembly 3.1 Target Framework is missing

This is OK. This is the latest version of Blazor WebAssembly App: .NETStandard 2.1

A Blazor WebAssembly App, unlike Balzor Server App , runs under the Mono runtime. It is not .Net Core.
