Android Hybrid Template throws exception

ran

dotnet new -i Microsoft.MobileBlazorBindings.Templates::0.5.50-preview
dotnet new blazorhybrid -o FirstBlazorHybridApp

and then ran the android project and got this

I’m pretty sure it has got to do with the fact that somehow on some platforms a newer version of System.Memory is pulled in from nuget instead of from the framework (it should pickup the framework version. I.E. the mono or .net core versions, never the nuget). The nuget version does not contain the new Span<T> and Memory<T> types that System.Text.Json needs.

We add a package reference to each android project through the props files inside the nuget with the right version and IncludeAssets=“none” to fix this. This works for visual studio and cmdline builds.

However I get a feeling that with other IDEs than visual studio 2019 for windows this does not work, which would mean that an application configuration file with the right binding redirects would need to be generated (or be made by you).

What sometimes also works is removing the reference to System.Memory inside the project file if it uses old style references with hint paths.
