Roslyn Code Refactoring, which provides sync to async method conversion with propagation across method call-chain and inheritance chain. Also supports reverse async to sync conversion
You need to point Omnisharp to folder, containing AsyncPropagationRefactoring.dll using omnisharp.json.
For example, if AsyncPropagationRefactoring is installed like this: nuget install AsyncPropagationRefactoring -o c:\refactorings, then config section of omnisharp.json should look like this:
{
"RoslynExtensionsOptions": {
"locationPaths": [
"C:\\refactorings\\AsyncPropagationRefactoring.0.2.0\\lib\\netstandard2.0"
]
}
}omnisharp.json can be placed at the root of your solution, or globally into %USERPROFILE%/.omnisharp/.
After reloading OmniSharp you can use refactoring on methods through ctrl+. context menu.
Visual Studio have support for loading refactorings from assemblies, added to project.
This way, AsyncPropagationRefactoring nuget package can be installed into project and become available through ctrl+. context menu for this project.
