with OmniSharp enabled.
To switch between C# Dev Kit and OmniSharp:
Platform specific setup
You may need to follow additional directions, depending on your development environment.
In order to run Skia+GTK heads, you will need to make sure to install the GTK3 runtime.
Tip
Once the GTK3 runtime is installed, you will need restart your IDE for the changes to take effect.
To install on CI using Azure Pipelines, use the following step:
steps:
- powershell: |

$destination = "gtk3-runtime.exe"
Invoke-WebRequest $source -OutFile $destination
Start-Process -FilePath "gtk3-runtime.exe" -Wait -PassThru -ArgumentList /S
Write-Host "##vso[task.setvariable variable=PATH;]${env:PATH};C:\Program Files\GTK3-Runtime Win64\bin";
