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

Question

Trying to migrate from ASP.NET Core 3.1 to 5.0 using this guide provided by Microsoft.

Installed SDK 5.0.100-rc.1 with runtimes. Updated project as guide says and still getting following error:

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

Project file:

<Project Sdk="Microsoft.NET.Sdk.BlazorWebAssembly">
    <PropertyGroup>
        <TargetFramework>net5.0</TargetFramework>
        <UserSecretsId>*****</UserSecretsId>
    </PropertyGroup>
...

Cant find anything asociated with this error. I have no idea where to search for more info.

Thank you for any idea.

Answer 1

I finally made it work.

I did everything that guide said, except for the project file which I changed to this:

<Project Sdk="Microsoft.NET.Sdk.Web">

  <PropertyGroup>
    <TargetFramework>net5.0</TargetFramework>
    <UserSecretsId>*****</UserSecretsId>
    <UseBlazorWebAssembly>true</UseBlazorWebAssembly>
  </PropertyGroup>
...

But I have no idea if it is correct when official upgrade guide says to use:

<Project Sdk="Microsoft.NET.Sdk.BlazorWebAssembly">

instead of:

<Project Sdk="Microsoft.NET.Sdk.Web">
