Hello World! program with comments fails

Description (optional)

This section should contain an expanded description
of the bug, if the title is not sufficient.

Reproduction Steps

Run this code

[ This program prints "Hello World!" and a newline to the screen, its
  length is 106 active command characters. [It is not the shortest.]

  This loop is an "initial comment loop", a simple way of adding a comment
  to a BF program such that you don't have to worry about any command
  characters. Any ".", ",", "+", "-", "<" and ">" characters are simply
  ignored, the "[" and "]" characters just have to be balanced. This
  loop and the commands it contains are ignored because the current cell
  defaults to a value of 0; the 0 value causes this loop to be skipped.
]
++++++++               Set Cell #0 to 8
[
    >++++               Add 4 to Cell #1; this will always set Cell #1 to 4
    [                   as the cell will be cleared by the loop
        >++             Add 2 to Cell #2
        >+++            Add 3 to Cell #3
        >+++            Add 3 to Cell #4
        >+              Add 1 to Cell #5
        <<<<-           Decrement the loop counter in Cell #1
    ]                   Loop until Cell #1 is zero; number of iterations is 4
    >+                  Add 1 to Cell #2
    >+                  Add 1 to Cell #3
    >-                  Subtract 1 from Cell #4
    >>+                 Add 1 to Cell #6
    [<]                 Move back to the first zero cell you find; this will
                        be Cell #1 which was cleared by the previous loop
    <-                  Decrement the loop Counter in Cell #0
]                       Loop until Cell #0 is zero; number of iterations is 8

The result of this is:
Cell no :   0   1   2   3   4   5   6
Contents:   0   0  72 104  88  32   8
Pointer :   ^

>>.                     Cell #2 has value 72 which is 'H'
>---.                   Subtract 3 from Cell #3 to get 101 which is 'e'
+++++++..+++.           Likewise for 'llo' from Cell #3
>>.                     Cell #5 is 32 for the space
<-.                     Subtract 1 from Cell #4 for 87 to give a 'W'
<.                      Cell #3 was set to 'o' from the end of 'Hello'
+++.------.--------.    Cell #3 for 'rl' and 'd'
>>+.                    Add 1 to Cell #5 gives us an exclamation point
>++.                    And finally a newline from Cell #6

Expected Behavior

Prints hello world

Actual Behavior

[RUNTIME ERROR] Undefined function call

Repro steps for .NET Native startup crashes

Hey @alwu-msft, thank you for the help!

As I mentioned in my VS issue, I had two crashes related with .NET Native.
The related GitHub issue is this one: microsoft/microsoft-ui-xaml#2545.

Now, the crash in Release is actually vanished somehow and I can't reproduce it anymore not even by checking out to a past commit. The only thing I can think of is that I've updated my PC from 19041.264 to 19041.329, not sure how that might be related though.

I also tried checking out to one of the repro branches I had made for @LanceMcCarthy and I can't repro the Release crash there anymore either, so it does seem to be related to maybe the latest Windows 10 update, or some other thing external to my code and NuGet packages in use 🤔

That said, I can still reproduce the crash in Debug with .NET Native though:

• Clone the repo and switch to repro/sdk-cras-release (the issue appears on master too, this branch is just easier to test though as I've removed a lot of non UI-specific code and projects)
• Open the solution
• Right click on Brainf_ckSharp.Uwp > properties > Build
• Select the Debug x64 config and tick "Enable .NET Native toolchain"
• Set that project as startup project
• Run the project

I'm getting a startup crash when doing so, see screen here:

Let me know if there's anything I can do to help on my end too, and thanks again! 😄

Double Check Microsoft.UI.Xaml Replaces Windows.UI.Xaml

When right-clicking on the Textbox, the application crashes. The following output is available in the Windows Event Viewer

Sergio has shared a screenshot (from DevCenter?) that further implicates the issue is in Windows.UI.Xaml in the crash

I'm surprised that Windows.UI.Xaml is being used instead of Microsoft.UI.Xaml, but I'm not well versed in how the WinUI sets the types under the covers. This could well be the expected output for a crash on a WinUI ContentPresenter.

Possible duplicated file

Is this just a leftover file after a casing change or desired?

warning: the following paths have collided (e.g. case-sensitive paths
on a case-insensitive filesystem) and only one from the same
