Avoid duplicate Microsoft.CodeAnalysis DLLs #48840
Description
With the dotnet run app.cs feature, we now deploy Microsoft.CodeAnalysis.CSharp.dll next to dotnet.dll in the SDK. But that seems unnecessary since we have another copy of that in Roslyn/bincore. We could remove the DLLs in the root folder and make dotnet.dll load the ones from Roslyn/bincore. Perhaps through probing paths in deps.json.
