the examplecode opens without errors

In the examplecode that shows up after the project-creation-process, using Sys = Cosmos.System , BeforeRun() , Run() is marked as an Error.

There are allso 8 Errors in the Errorlist:

Reproduction - How did you get this error to appear?

I installed the cosmos “User Kit” as explaned on the cosmoswebsite https://www.gocosmos.org/docs/install/ Then I started creating my project like this github site explains https://github.com/CosmosOS/Cosmos/wiki/Develop-Your-Own-Operating-System-in-C%23-or-VB.NET

When the project was displayed, there were these errors.

Version - Were you using the User Kit or Dev Kit? And what User Kit version or Dev Kit commit (Cosmos, IL2CPU, X#)?

I was using the CosmosUserKit-20190628-vs2019.

Yes, visual studio community 2019 is supported. Although gocosmos.com’s tutorial is outdated, the perquisites it lists for the userkit are still required for visual studio 2019. The most recent release to the userkit is the first to support only vs 2019, before that, they supported only vs 2017.

Hello; I’m bumping this issue since I have produced the same errors as the op’s first post from creating a new Cosmos project.

Out of curiosity, what prerequisites are needed for Cosmos to run on VS 2019 Community (if it is supported)? The installation guide on gocosmos.com seems to be outdated and only outlines installation for VS 2017.
