[Bug]: Escape , and ;= doesn't work for global property when build with dotnet, but html encode %3C and %3B= works well

[JaynieBai]

Issue Description

1. Test escape ',' and "," and %3C in the powershell , cmd, bash and zsh. Found "," and ',' is not supported in the following 4 shells and cmd error is different from others.

2. Test ";=" and ';=' and %3B in 4 shells. Found when ";=" and ';=' global property, it reports error in 4 shells with the same error MSB1006: Property is not valid. But = and ; work well separately for global property

Powershell

With quotes: MSBUILD : error MSB1005: Specify a property and its value.

With double quotes: MSBUILD : error MSB1005: Specify a property and its value.

Html Codes. Works well

CMD

With quotes: MSBUILD : error MSB1006: Property is not valid.

With double quotes: MSBUILD : error MSB1005: Specify a property and its value.

@JaynieBai could you please check whether it is shell or msbuild parsing causing this error? For that, please check which parameters msbuild received. You can set $env:MSBUILDDEBUGONSTART=1, run the build, start debugging and look the parameters that msbuild received in the code.

When run with dotnet, the CommandLine is D:\WORK\msbuild\artifacts\bin\bootstrap\core\sdk\9.0.100-rc.1.24452.12\MSBuild.dll .\MyApp.csproj /p:F1=,

When run with msbuild.exe, the CommandLine is D:\WORK\msbuild\artifacts\bin\bootstrap\net472\MSBuild\Current\Bin\MSBuild.exe .\MyApp.csproj /p:F1=","

So for dotnet build, we have to execute dotnet D:\WORK\msbuild\artifacts\bin\bootstrap\core\sdk\9.0.100-rc.1.24452.12\MSBuild.dll .\MyApp.csproj /p:F1=\",\" with escape character "
