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

问题

I'm getting this error: enter code hereSystem.TypeLoadException: Could not resolve type with token 0100001a from typeref (expected class 'System.Threading.Tasks.Task' in assembly 'System.Runtime, Version=4.2.2.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a')

When I switch to:

<TargetFramework>netcoreapp3.1</TargetFramework>

<TargetFramework>netcoreapp5.0</TargetFramework>

from netstandard2.1

My packages are:

<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="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.SpeechSynthesis" Version="8.0.0" />

Any ideas to resolve this problem?

I think, this question has been answered here:

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.
