How do I edit LINQPad.UserQuery.exe.config?

unarist

I want to edit LINQPad.UserQuery.exe.config because configuration/runtime/NetFx40_LegacySecurityPolicy element is not worked in LINQPad.config.

Actually, I can edit both C:\Program Files (x86)\LINQPad4\LINQPad.exe.config and AppData\Local\LINQPad\ProcessServer5X86\LINQPad.UserQuery.exe.Config but later one is overwritten at LINQPad launching.

What is the correct way to edit LINQPad.UserQuery.exe.config?

Create a file called LINQPad.config in the directory where LINQPad.exe exists.

LINQPad will then pick that up and use it for your queries.

NetFx40_LegacySecurityPolicy configuration doesn't seem to work in LINQPad.config unlike other configurations. The configuration is used for avoiding CAS Policy compatibility issue.

For example, below code causes NotSupportedException in .NET 4 without setting it.

// Add reference for System.Security.dll and import namespace System.Security.
new HostSecurityManager().DomainPolicy

And my results are:
- in LINQPad.config: NG
- in LINQPad.UserQuery.exe.config: OK
- in LINQPad.exe.config: OK (with disabling "Run each query in its own process")

Understood.

I'll fix this in the next beta, so that LINQPad.exe.config works whether or not you enable "Run each query in its own process".
