So my idea is I want to see what an object's members or properties would return/change while I am debugging/tracing. There is Object Browser but it is only to show tree list of an object.

For example, let's say

var cacheDir = cotext.CacheDir;

But I want to change .CacheDir to .ExternalCacheDir while debugging to see what value would be returned to the variable.

var cacheDir = context.ExternalCacheDir;

Otherwise, I have to change it in editing mode and restart the whole debugging process. I think that we can do something like this in browser developer console or Jupyter notebook like CLI environment.

With C# Keyboard settings you press Ctrl+Alt+I - the immediate window. Or via the Command window type Immed.

In the Immediate Window you can do ad-hoc commands.

So in the debugger IDE you'd step over the line of code:

var cacheDir = cotext.CacheDir;

And now you want to tweak it just a once off, Ctrl+Alt+I

Then paste:

cacheDir = cotext.ExternalCacheDir;

And press enter. You can always revert back in the immediate window, eg:

cacheDir = cotext.CacheDir;

If you just want to see the value of a variable you can do a ? cacheDir to see the values. Give it a go :)

While you're debugging, you can use Watch windows to watch variables and expressions.

Open a Watch window by selecting Debug > Windows > Watch > Watch 1, 
or pressing Ctrl+Alt+W > 1.

In the Watch window, select an empty row, and type variable or Expression

Continue debugging by selecting Debug > Step Into or pressing F11 as needed to advance.
The variable values in the Watch window change as you iterate through the for loop.

There are many ways to see variables values in VS. You can use the Watch Window, You can hover a variable and see a Data Tip, you can use the Immediate Window. You can also check OzCode that provides a HUD that shows the variable values without the need to open any Window, and provide a nice way to choose the properties that you like to present, and provides a google like search for variable name and values. In the next version of OzCode (you can download a preview version of it) you can use OzCode Predict that also support VS Edit&Continue.
