debuggung source map load issues with visual studio 2017 - visual-studio

So I have been working on an angular 1.x app using visual studio and Typescript when I noticed I was getting this error
SourceMap http://localhost:3131/Components/bbApp.js.map read failed: Unexpected character encountered while parsing value: <. Path '', line 0, position 0..'iexplore.exe' (Script): Loaded 'Sourcemap (http://localhost:3131/Components/account/account.js)'.
Trying to google that error or many versions of it hasn't produced anything useful. My question is how do you debug something like this and figure out what is causing it to complain when it loads?

Visual Studio 2019 Extension That Shows Errors inside the Code Editor

I've had to rebuild my machine lately and lost all the Visual Studio extensions I had installed.
I did have one that displayed error messages inside the code block, but for the life of me I cannot find it on the marketplace.
It does very similar things to this extension:
https://marketplace.visualstudio.com/items?itemName=AlexanderGayko.ShowInlineErrors
But the trouble with the extension above, is it writes the error over existing code, which makes it difficult to read.
Okay I've found it myself it's at the following URL

"UWPHost.pdb not loaded" - Debugging Xamarin UWP app

I have a Xamarin app for which I have been debugging the UWP app on my computer for testing.
I've been having difficulties debugging. I keep getting a 'No Symbols Loaded' error which goes onto say one of the following errors:
UWPHost.pdb not loaded
or
wkernelbase.pdb not loaded
Typically, restarting or rebuilding Visual Studio will sometimes resolve the issue temporarily. As a result of this, development has been an incredibly painful process.
Any idea how this sort of problem can be avoided?
Additionally, if it's not the PDB errors I get this instead:
Unable to activate Windows Store app ... 'The app didn't start'
These errors can happen with absolutely zero changes.
I'm new to Xamarin so I could be missing something blindingly obvious here.
Something I already tried was checking the 'Microsoft Symbol Servers' option via Visual Studio options.
I'm using Visual Studio 2019.
UPDATE:
I changed the following Visual Studio option:
Tools -> Options -> Debugging -> General -> Enable .NET Framework source stepping
This allowed me to see the following error:
Unhandled exception at 0x7747C762 (KernelBase.dll) in Framework.UWP.exe: 0xE0434352 (parameters: 0x8007000B, 0x00000000, 0x00000000, 0x00000000, 0x03B40000). occurred

Assembly in Visual Studio 2012 - Red syntax error

I'm using Visual Studio 2012 and I've just created a platform for ASM using Irvine Tutorial at http://kipirvine.com/asm/gettingStartedVS2012/index.htm
Everything works just fine, In order to create a new project I just open an existing project of Irvine Examples and add my own assembly file (otherwise in case I create my own project I get error regarding missing EXE file).
The more complicated issue is the syntax of the Visual Studio. I'm getting a red underline under comments as you can see in the attached image.
These errors don't prevent compiling or running of the ASM program but it is really annoying to view tbe code or writing the code with these strong red syntax errors in front of the eyes.
Do you know this issue? How can I fix it? Why does it happen? Is it realted to the intellisense?
See attached image :
Thank you

how to stop the showing error message in visual studio for jscript in visual studio 2010

i am using IE 8 for testing the javascript i write for my web-application. i use something who are not unknown for IE 8 so they give me error each time
"Microsoft JScript runtime error: Object doesn't support this property or method".
are their any way to stop this error showing in visual studio when i debug the javascript.
when i refresh the page they give me error in visual studio. well i not want to see anything like showing error in visual studio.
so how i can disable the showing error for javascript in visual studio even i need to work with javascript breakpoint and trackpoint.
Unless I missed something, there's only three things I can think of:
Fix the bug
Debug in IE with the javascript debugger, instead of Visual Studio
Fix the bug
I recommend 1 or 3 ;)
