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.
The language service is for intellisense in Visual Studio. So if you are not using Visual Studio there is no need to install it. There is no blazor intellisense support for VSCode right now or something.
See here for the 7.3 error.
