How to have multiple dotnet commands in cdk.json?

[Aracron]

I was trying to follow the sample below. The app parameter has multiple dotnet commands with a semicolon delimeter. Essentially, it is building the Lambda code and publishing to a "dist" folder before it builds the main stack project. When I try this, I get an MSBuild error (MSB1005). It looks like it is just throwing the second command in as a parameter, and it is complaining that I did not have a proper property and value combination. I am on VS 2022 with MSBuild 17.4. Any ideas on what is wrong? I have verified that the individual dotnet commands work when invoked separately.
