[dotNetRDF-Support] Is there a way to configure a Sparql endpoint using the in-memory with persistence?

[Mark S. <Ma...@Sk...>]

I've got your dotNetRDF Sparql/Update endpoints setup and working in IIS
but there is no persistence of the updates back to the source .ttl file.  I
see that there is a PersistentTripleStore class and tried configuring it in
the config.ttl but got a "cannot load object" error when experimenting with
the Sparql web interfaces.  I suspect that using SQL would resolve this but
prefer the in memory approach for our needs now?

Is there currently a way to configure a Sparql endpoints using in memory
store with persistence?
If not,would adding PersistentTripleStore to the ConfigurationLoader class
be the way to add this type  of support?

Thanks,
