[Boshwa]

Type: Bug

Behaviour

Expected vs. Actual

Expected: To be able to use Iron Python 2.7 as my interpreter, which is usable in older versions of the extension.
Actual: Get error "An Invalid Python interpreter is selected, please try changing it to enable features such as IntelliSense, linting, and debugging. See output for more details regarding why the interpreter is invalid."

Steps to reproduce:

3. Run Python:Select Interpreter
4. Select C:\Program Files\IronPython 2.7\ipy.exe

We don't support python 2.7, the extension works with currently supported version listed on python.org. You can pin the extension to 2022.8.* to use 2.7.
