我已将我的 blazor 客户端项目项目从 preview7 更新到 preview 8，使用 Visual Studio 2019 运行。
我已按照此处详述的说明进行操作；
.NET Core 3.0 Preview 8 中的 ASP.NET Core 和 Blazor 更新
但是，当我构建解决方案时，会出现以下错误；

Blazor 客户端项目引用的唯一其他项目是引用.Net Standard 2.1.
我在 Blazor 客户端项目的依赖项 -> 分析器中列出了以下内容。
最后我.csproj的是
<Project Sdk="Microsoft.NET.Sdk.Web">
<PropertyGroup>
<TargetFramework>netcoreapp3.0</TargetFramework>
<OutputType>Exe</OutputType>
<LangVersion>7.3</LangVersion>
<RazorLangVersion>3.0</RazorLangVersion>
</PropertyGroup>
<PropertyGroup Condition="'$(Configuration)|$(Platform)'=='Debug|AnyCPU'">
<OutputPath></OutputPath>
</PropertyGroup>
<ItemGroup>
<PackageReference Include="Blazored.LocalStorage" Version="2.0.12" />
<PackageReference Include="Microsoft.AspNetCore.Blazor" Version="3.0.0-preview8.19405.7" />
<PackageReference Include="Microsoft.AspNetCore.Blazor.Build" Version="3.0.0-preview8.19405.7" PrivateAssets="all" />
<PackageReference Include="Microsoft.AspNetCore.Blazor.HttpClient" Version="3.0.0-preview8.19405.7" />
<PackageReference Include="Newtonsoft.Json" Version="12.0.3-beta1" />
</ItemGroup>
<ItemGroup>
<ProjectReference Include="..\OakfieldLeasing.Blazor.Shared\OakfieldLeasing.Blazor.Shared.csproj" />
</ItemGroup>
<ItemGroup>
<Folder Include="wwwroot\images\" />
</ItemGroup>
</Project>
我也尝试过Newtonsoft.Json用Microsoft.AspNetCore.NewtonsoftJsonNuget 包替换，但这似乎没有什么区别。
请问有人知道是什么原因造成的吗？
