Concatenating a variable and a string literal without a space in PowerShell
Another option and possibly the more canonical way is to use curly braces to delineate the name:
$MyVariable = "Some text"
Write-Host "${MyVariable}NOSPACES"
This is particular handy for paths e.g. ${ProjectDir}Bin\$Config\Images. However, if there is a \ after the variable name, that is enough for PowerShell to consider that not part of the variable name.
You need to wrap the variable in $()
For example, Write-Host "$($MyVariable)NOSPACES"
