.NET 6预览版4:Microsoft没有运行时包。AspNetCore。应用程序可用于指定的运行时标识符“browser wasm”

我正在使用。网 6.0.100-preview.4.21255.9 ,ASP。NET Core Blazor WebAssembly 6.0.100-预览。4.21255.9 .我试图通过以下方式覆盖默认标识UI:添加对NuGet package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 )但添加此NuGet包时出错(另一个NuGet包还可以)

主要错误信息:

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

当我点击查看细节错误时,它指向

<ResolveRuntimePackAssets FrameworkReferences="@(FrameworkReference)"
                          ResolvedRuntimePacks="@(ResolvedRuntimePack)"
                          UnavailableRuntimePacks="@(UnavailableRuntimePack)"
