New projects created with abp suite Blazor WebAssembly template does not compile:
NETSDK1082 Microsoft.AspNetCore.App 没有运行时包可用于指定的 RuntimeIdentifier“browser-wasm”。 NJIS.IMP.Platform.Blazor.Host.Client C:\Program Files\dotnet\sdk\8.0.303\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.Sdk.FrameworkReferenceResolution.targets.
Chaning the blazor project file as follows can make it compile.
