*
* On mobile, the default provider is specified at compile time using a property
* in the .csproj file (which can be set from the IDE). When using the linker, all
* other providers will be linked-out, so you won't be able to choose a different
* provider at run-time.
*
* On desktop, the default provider can be specified with the MONO_TLS_PROVIDER
* environment variable. The following options are currently supported:
*
* "default" - let Mono pick the best one for you (recommended)
* "old" or "legacy" - Mono's old managed TLS implementation
* "appletls" (currently XamMac only, set via .csproj property)
* "btls" - the new boringssl based provider (coming soon).
*
* On all platforms (except mobile with linker), you can call
*
* MonoTlsProviderFactory.Initialize(string)
*
* to use a different provider.
