Hi All, The Dynamic resource is awesome feature that Pulumi providing, However it is not available in .NET yet. Is there any workaround or time line to bring this feature available in .NET?

no, we have no timeline for that. Function serialization is not easy to implement in dotnet https://github.com/pulumi/pulumi/issues/3638

Function serialization isn't easy but we're are considering using a library that I developed before joining Pulumi to try doing this. It would be very experimental to start with.
