.NET 6 预览版 4：Microsoft.AspNetCore.App 没有可用于指定 RuntimeIdentifier 'browser-wasm' 的运行时包

Question

我正在使用 .NET 6.0.100-preview.4.21255.9，ASP.NET Core Blazor WebAssembly 6.0.100-preview.4.21255.9。我尝试通过这种方式覆盖默认标识 UI：添加对 NuGet 包的引用]Microsoft.AspNetCore.Identity.UI](https://www.nuget.org/packages/Microsoft.AspNetCore.Identity.UI/6.0.0-preview.4.21253.5?_src=template) 但是添加此 NuGet 包时发生错误（另一个 NuGet 包没问题）

Severity    Code    Description Project File    Line    Suppression State
Error   NETSDK1082  There was no runtime pack for Microsoft.AspNetCore.App available for the specified RuntimeIdentifier 'browser-wasm'.    acc.Client  C:\Program Files\dotnet\sdk.0.100-preview.4.21255.9\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.Sdk.FrameworkReferenceResolution.targets 391 
Error   NETSDK1082  There was no runtime pack for Microsoft.AspNetCore.App available for the specified RuntimeIdentifier 'browser-wasm'.    acc.Client  C:\Program Files\dotnet\sdk.0.100-preview.4.21255.9\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.Sdk.FrameworkReferenceResolution.targets 391

主要错误信息：

There was no runtime pack for Microsoft.AspNetCore.App available for the specified RuntimeIdentifier 'browser-wasm'

当我点击查看详细错误时，它指向

<ResolveRuntimePackAssets FrameworkReferences="@(FrameworkReference)"
                          ResolvedRuntimePacks="@(ResolvedRuntimePack)"
                          UnavailableRuntimePacks="@(UnavailableRuntimePack)"
                          SatelliteResourceLanguages="$(SatelliteResourceLanguages)"
                          DesignTimeBuild="$(DesignTimeBuild)">
  <Output TaskParameter="RuntimePackAssets" ItemName="RuntimePackAsset" />
</ResolveRuntimePackAssets>

（文件 C:\Program Files\dotnet\sdk.0.100-preview.4.21255.9\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.Sdk.DefaultItems.targets 。摘自 https://gist.github.com/donhuvy/d98d59e8af9947e37e6d4fe85004e444#file-microsoft-net-sdk-frameworkreferenceresolution-targets-L391-L397 ）

如何添加NuGet包UI成功？
