I am learning how to build a Blazor app from this tutorial. The required tools are given as follows.
Because downloading and installing VS 2017 take much time, I just installed the SDK. I also downloaded the language service (
.vsix file) but don't know how to install it.
The following steps succeeded.
md test cd test dotnet new -i Microsoft.AspNetCore.Blazor.Templates dotnet new blazor -o ba1 cd ba1
But the following
produces an error as follows:
CSC : error CS1617: Invalid option '7.3' for /langversion. Use '/langversion:?' to list supported values. [C:\Users\amd\test\ba1\ba1.csproj]
It seems I need to install the language service, but how can it be done without VS 2017?
For answering the comment why I did not install VS 2017 and assume (I did not assume actually) it optional, see the excerpt taken from the tutorial.
