Getting started with Blazor

Blazor – Microsoft’s new web technology. I read a lot about the new possibilities and decided to get started with Blazor. My first step was visiting https://docs.microsoft.com/de-de/aspnet/core/blazor/get-started?view=aspnetcore-3.0&tabs=visual-studio to get all information about how to install Blazor and how to programm my first code example. I downloaded the latest version of the .net Core SDK v3.0.0-preview9 from https://dotnet.microsoft.com/download/dotnet-core/3.0 and installed the Blazor templates by command shell.

dotnet new -i Microsoft.AspNetCore.Blazor.Templates::3.0.0-preview9.19424.4
Now I wanted to create a new project and select Blazor as template. But there were no .net core 3 templates in the selection only core 2.1 and 2.2 project templates. Afterwords I tried many things to get it working but nothing helped.
Solution: I should have read the instructions in a better and more sensible way. I missed an important detail: The latest .net Core 3 preview version only works with the latest Visual Studio preview version.

My installed version of Visual Studio was Community Edition 16.2.5. No chance to run the latest SDK version. I had to deinstall SDK 3 preview 9 and installed v3.0.0-preview6 because this SDK version supports Visual Studio 2019 v16.2.
Coming back to Visual Studio and creating a new project I could choose from .net Core 3 templates as expected.
