问题:

I uses LinqPad for running code snippets.

I need to run some code that targets 3.5 for which there is separate legacy build.

My question is how to run linqpad side by side?

回答1:

LINQPad 2.x and LINQPad 4.x are totally independent and happily run side-by-side. This is true whether you're using the the installed version or the standalone executable. Regarding updates, these are also independent: LINQPad 2.x stores updates in %programdata%\updates whereas LINQPad 4.x stores updates in %programdata%\updates40.

What exactly happens when you run LINQPad 2.x? What version does it say is running in Help | About?

I take it you have .NET Framework 3.5 installed on the machine?

回答2:

If you are having trouble running both versions side by side try downloading the portable versions of the application.

Edit
It appears there is no portable version of LINQPad 2 available for download. You can try installing the v2 and then download a portable version of v4.
