Hi,

I took today the latest version 2.0.2 and while the UI profiling works like charm, thank you, but for some reason I could not find a way to set the DB profiling at all.

The thing is I am using Devart’s Oracle connector 6.8 and EF code first (EF is 4.3) with MVC 4.

When setting the MiniProfilerPackage.PreStart() I am clueless on what to do to give it the right DbConnection that i can get from Devart. If i do:

```
var conn = new OracleConnection(“connection string here”); var profiled = new ProfiledDbConnection(conn, MiniProfiler.Current);

MiniProfilerEF.Initialize();

```

I keep getting this error:

Unable to cast object of type ‘StackExchange.Profiling.Data.EFProfiledDbConnection’ to type ‘Devart.Data.Oracle.OracleConnection’.

Is there any possibility to make this combination work?

Thank you for this great tool.

are you using the MiniProfiler.EF nuget package? it includes all the magic needed to profile EF
