Linqpad6 : exception when dumping to DataGrid

sgmoore · August 2019

A simple query like

Area.Dump(true);

will throw an exception

Could not load file or assembly 'System.Reflection.Emit.Lightweight, Version=4.1.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. The system cannot find the file specified.

Area.Dump(false); works ok, but I get the same error if I click on the right arrow and select 'View in grid'

(new { a= 1, b =2}).Dump(true); also works

but the following doesn't

void Main()
{
    List<Record> records = new List<UserQuery.Record>();
    records.Add(new Record());  
    records.Dump(true); 
}

public class Record
{
    public int Id ;
     public string Code ;
}

Can you run this query please and post the results:

Util.Framework.GetReferenceAssemblies().Dump();
Util.Framework.GetRuntimeAssemblies().Dump();

You'll still on netcore3 preview 6. Could you try updating to preview 7?

That fixes it.

Thanks.
