Error: the type or namespace name does not exist in the namespace using visual studio 2017

When compiling an error will occur that a name space does not exist. An example error like the message below:
The type or namespace name 'Microsoft.Office.Interop.Outlook' does not exist in the namespace 'Microsoft'(are you missing an assembly reference?)
The system is trying to find a reference for a specific namespace or dll.
One solution for this is to add the reference to the missing namespace.
Find the “solution explorer” window like the image below:

After opening the “solution explorer” window, right click the name of the project just below the solution explorer. Beside the C# icon.
A new window will open like the image below. Click “Add”, then click “Reference”.

After clicking “Reference”, the “Reference Manager” window will open.
Click “COM” option, then use the filter option to go directly to the desired namespace or reference. Since the error is a Microsoft namespace, type “Microsoft” and “Microsoft” namespace will be filtered from the list. See image below…

PowerShell Insert Multiple Lines or text to another file dynamically

Copying and pasting text to another file is a common thing to do, copy and paste done. Boom!
In PowerShell scripting copying and pasting text from one file to another dynamically isn’t as easy as it is done in a spreadsheet or document. Dynamically while the code is running  and doing things in the background without human intervention.
As the odds say, if there’s a will there’s a way. And making things efficient and easy is a good way in life.
If ever a scenario occurs that you need to copy text or lines in a file from one file to another, without breaking the code execution. Script below works just fine. Just insert the code where it is needed.

PowerShell code snippet:
$reader=[System.IO.File]::OpenText("D:\test-read-paste\main1.txt") #get-content can also be used
$lineNumberx=3 #adjust this number where you need to start inserting the text
#Loop line by line and process while($null-ne ($line=$reader.ReadLine())) {

PowerShell repeat spaces or characters

Example code of repeatingspaces within a string:
$xrepeat = ' ' * 11 $string_with_spaces = “ Hello World of Spaces!!!”
Write-output $xrepeat $string_with_spaces
Output image:

To indent or tab a string:
$Tab = [char]9 Write-Output "$Tab Hello Tab Indention!!!"
Output image:

To add other HTML character in PowerShell string:
$Euro_symbol = [char]8364 Write-Output "$Euro_symbol Hello Euro Symbol in PowerShell!!!"
Output image:
