説明

Version Used: Visual Studio 2019 v16.11.4.

Steps to Reproduce:

  1. Start debugging of any project.
  2. Enter any multi-statement line into the Immediate Window. For example, int i = 3; i = 1337;
  3. Press Enter.
  4. Enter the expression i and press Enter again, to examine the current value of the variable.

Expected Behavior: Immediate Window should execute every statement and tell me that i = 1337.

Actual Behavior:

int i = 3; i = 1337;
Expression has been evaluated and has no value
i
3

Notably, if I enter a slightly different statements:

i = 3; i = 1337;

then the expression compiler generates an error message:

error CS1073: Unexpected token ';'
