Debugger: Some extension method evaluated in watch window would lead an error

[GraceDong]

Environment data

dotnet --info output:
VS Code version:
C# Extension version:

Steps to reproduce

1 Set a breakpoint at line of " _appSettings = options.Value; " in HomeController.cs
2 Press F5 to start debugging
3 Add a expression " "Hello".AsParallel()" in watch window
4 Press Enter

Expected behavior

The value should display with "This expression causes side effects and will not be evaluated"

Actual behavior

The value displays with '
error CS1061: 'string' does not contain a definition for 'AsParallel' and no extension method 'AsParallel' accepting a first argument of type 'string' could be found (are you missing a using directive or an assembly reference?)'

@GraceDong the problem here is almost certainly going to be that the EE cannot load the assembly with the AsParallel method in it. Can you have the program stop after an AsParellel in the program has successfully executed?

I apologize for my late reply. When I use 1.4.1 beta-7 C# extension, add the expression in watch window, the value displays with "not available". I can stop the program after an AsParellel in the program has executed and I think the EE cannot load the assembly with the AsParellel method in it.
