ok, I see this entry about a Mono.Sharp conflict in error list as warning when I try to compile an the android app of xamarin.forms project which uses old packages.config:

so it was not possible to use the mono nuget all time?

then it causes compile errors or even errors during installation

Warning has gone When I down grade version to Xamarin.HotReload 1.4.15

I need to build a repro, which may take some time. Your demo uses packagesreference include, which causes startup crash for me in Visual Studio 2017 because the reference assembly is used instead of real implementation.

You added the reference here , but in Xamarin.Forms.HotReload.Reloader.csproj you use <PackageReference Include="Mono.CSharp" Version="4.0.0.143" /> I think here is the mismatch.

So use Mono.CSharp NuGet in all places or the frameworkAssembly assemblyName=“Mono.CSharp” and remove the nuget package and let us test which version version best
