blazor template can't build on cli

Question

Hello
dotnet new build blazor creates project.
When building with dotnet;

C:\Users\ramdem.nuget\packages\microsoft.aspnetcore.blazor.build\0.7.0\targets\RazorCompilation.targets(184,5): Error: rzc generate exited with code 1.

Project build fails
.
Also Nuget reports package "microsoft.aspnetcore.blazor.build"is deprecated.

is there a solution here?

I'm confused, Visual studio template uses netcoreapp3.1 and build and run okey. But dotnet cli uses netstandard2.0 it fails.

Hi, @ram dem ,

Blazor template have been renamed. You can read more about that change in the 'Blazor templates renamed and simplified' section in the Preview 8 Release Blog Post.

Try to update Blazor templates and create Blazor Server App or Blazor WebAssembly App.

1. Install latest Templates

   dotnet new --install Microsoft.DotNet.Web.ProjectTemplates.3.1::3.1.10  
   

dotnet new --install Microsoft.DotNet.Web.ProjectTemplates.3.1::3.1.10
