Command console C# app task

To understand this micro project first create this 1 line file named 2settings.txt:
ThisIs1stKey:Abc;SecondKey:DEF;
Note, the string 'ThisIs1stKey' is a key and 'Abc' is its value.
Note, the string 'SecondKey' is a key and 'DEF' is its value.
This is a simple example of a 1 line file I created using Notepad.
...
I'd like a command console app provided in C# and named PrintValue.cs
App must handle this 2 argument usage syntax: PrintValue.exe file key
ex: If usage is 'PrintValue.exe 2settings.txt ThisIs1stKey' print: Abc
Terminate after printing value. Some error handling also appreciated.
Examples of errors could be "File not found." or "Key not found."
...

Above are project specs. Whoever would do this should first check with
me to confirm we're both able to build a simple C# app same way I build.
Let's check if we use same or close Visual Studio version. I have VS2019.
Thanks in advance for your interest. I will check back in few hours.
