Interactive session errors on references to system assemblies in C# script #24
Description
What steps will reproduce the problem?
Create an empty LINQPad query file named Empty.linq then compile and run it as follows from a Windows Command Prompt (assuming current directory is same as where the query file is saved):
lpless -t csx Empty.linq && Empty
The script should run without errors and emit a blank line. The compiled Empty.csx will look as follows:
#r "System.dll"
#r "Microsoft.CSharp.dll"
#r "System.Core.dll"
#r "System.Data.dll"
#r "System.Data.Entity.dll"
#r "System.Transactions.dll"
#r "System.Xml.dll"
#r "System.Xml.Linq.dll"
#r "System.Data.Linq.dll"
#r "System.Drawing.dll"
#r "System.Data.DataSetExtensions.dll"

System.Console.WriteLine(
);Run a C# Interactive 2.0 (csi.exe) session and copy the content of the compiled Empty.csx above and paste it into the session.
What is the expected output? What do you see instead?
Expected the session to have the same behavior as running the script via the batch (Empty.cmd). Instead, the session emits errors for references to all system assemblies except System.dll:
