Answer 1

The answer is that %2 becomes "/p:property" and %3 becomes "value".

Make this work in your batch file by using BOTH %2 and %3 and insert an = sign between them:

msbuild.exe %1.msbuild /t:%2=%3 %4 %5 %6 %7 %8 %9

and do not use the quote chars on the command line call. Use:

build App Target /p:property=value

For additional args with = signs just keep pairing them up.

I had the same issue with a simple batch file to run youtube-dl where the URL I pass has an = sign in it. solved as :

@echo off
REM YTDL audio only
echo %1=%2
youtube-dl -f bestaudio --extract-audio --audio-format mp3 --audio-quality 0 %1=%2
