Error is shown when creating Cesium App (or Lib) in Visual Studio

[pkazakov-dev]

Visual Studio version: 18.3.1

As a VS user I install Cesium templates using the steps from the README.md:

$ dotnet new install Cesium.Templates

Note that the templates are installed from Cesium.Templates folder of Cesium repo. More info is here: https://learn.microsoft.com/en-us/dotnet/core/install/templates?pivots=os-windows#folder

When I open Create New Project dialog in VS, I see the installed templates:

However, when I press "Create" button in Template Creation dialog I see the following error:

I believe this is a problem, and I don't have any logs to understand what's going wrong on the Visual Studio side.
Please provide more info or any suggestions how to diagnose it.

Hey, was it before or after you installed a template using the relative path?

[pkazakov-dev]

@ForNeVeR Firstly, a template using a relative path was installed.
Then this issue was observed.

It seems these pages about VS extensibility need investigation.

One possibility we are considering is implementing a plugin for Visual Studio.

I'd really prefer to avoid that if possible (because it introduces new distribution requirements, a whole other ecosystem to care for, its own compatibility requirements etc. etc.).

If it's unavoidable — then we'll have to go ahead and implement it.
