Introduction
Dotnet preview6 sdk comes with Blazor server side templates. You need to install templates only if you want to create hosted, client side or libraries.
To install templates you should to use dotnet new -i with the name of template and, optionally, the version.
Issue
When you added the templates you forgot to set the version of templates, you did:
dotnet new -i Microsoft.AspNetCore.Blazor.Templates # Bad. Don't copy-paste
Instead of:
dotnet new -i Microsoft.AspNetCore.Blazor.Templates::3.0.0-preview6.19307.2
For this reason, do you have the blazorserverside for twice: one for each version.
Solution
Good news, it is easy to fix.
Step 1: remove wrong templates:
dotnet new -u Microsoft.AspNetCore.Blazor.Templates
Step 2: install [optionally] new ones. Remember you don't need this templates to create just a server side blazor app.
dotnet new -i Microsoft.AspNetCore.Blazor.Templates::3.0.0-preview6.19307.2
Enjoy with your labs.
