Which LINQPad am I running?

Question

According to the LINQPad website, there are several different builds

• The vanilla build ('download now' on the homepage)
• X64 build
• AnyCPU build http://www.linqpad.net/Beta.aspx

How can I tell which I am running? The Help / About screen has a version number, but doesn't talk about platform.

Answer 1

The X64 build and the AnyCPU build are one and the same thing. I'll update the web site to make that clearer.

The Help | About screen will display (AnyCPU) after the version number if you're running that version.

Answer 2

This may be an option as well.

There's a VS utility call CorFlags that can force an AnyCPU assembly to explicitly be 32bit on a 64 bit host.

I have added to environment variables (computer properties/advanced settings) to my host for easy conversion:

%linq32% = corflags k:\Downloads\LINQPad.exe /32BIT+ /Force&&k:\Downloads\LINQPad.exe
%linq64% = corflags k:\Downloads\LINQPad.exe /32BIT- /Force&&k:\Downloads\LINQPad.exe
------line difference is here----------------------^

When you run this from the VS command prompt, the path to CorFlags has been added to the app's environment table (%path%). If you don't want to run from the VS command prompt, you'll need to fully qualify the path to CorFlags...and will likely need other paths added to %path%

The && in the above is a command separator for cmd.exe. CorFlags.exe runs first, then LINQPad.exe runs next.

So, i just run the VS command prompt and type %linq32% when i need it to run as 32bit and %linq64% when i need 64bit.

Helpful for loading your own assemblies that might be cross-bitness.

(note, while this comment may not be directly related, the search term "linqpad 32bit" show this post as #3 in google so i put here for others)
