      Description

      I'm unable to successfully execute any run commands using the new C Sharp driver. We previously used the C Sharp driver V1.1. Similar commands worked properly in that environment. In addition I'm also using the MongoDB Java driver V3.6.3. The exact same commands work properly via RunCommand.

      Here is the simplified VB source I'm using.
      Dim _oClient As MongoClient = Nothing
      Dim _oDatabase As MongoDatabase = Nothing
      Dim _oCommandResult As CommandResult = Nothing
      _oClient = New MongoClient("connstring")
      _oDatabase = _oClient.GetServer().GetDatabase(New MongoUrl("connstring").DatabaseName)
      Dim sCommand As String = "{aggregate:""restaurants"", pipeline:[{$group:{_id:""$borough"",borough:{$sum:1}}}]}"
      _oCommandResult = _oDatabase.RunCommand(sCommand)

      Here is the stacktrace that results. What is wrong? I get "no such command" messages no matter what syntax I try.

      Thanks in advance,

      Command {aggregate:"restaurants", pipeline:[{$group:{_id:"$borough",borough:{$sum:1}}}]} failed: no such command: '{aggregate:"restaurants", pipeline:[{$group:{_id:"$borough",borough:{$sum:1}}}]}', bad cmd: '{ {aggregate:"restaurants", pipeline:[{$group:{_id:"$borough",borough:{$sum:1}}}]}: 1 }'.
