Packages for the service fabric can contain multiple services. Their version numbers are documented in ApplicationPackageRoot/ApplicationManifest.xml of the package:
...
<ServiceManifestImport>
<ServiceManifestRef ServiceManifestName="VotingDataPkg" ServiceManifestVersion="1.0.29" />
</ServiceManifestImport>
<ServiceManifestImport>
<ServiceManifestRef ServiceManifestName="VotingWebPkg" ServiceManifestVersion="1.0.29" />
</ServiceManifestImport>
...
Question: Is it possible to read this version information from one of the .NET services in the package?
I want the web service in the package to read the version information from ApplicationManifest.xml and present it on his web page.
You can use the servicecontext which is supplied to you in "runasync" method and call context.CodePackageActivationContext and drill down to the package versions.
