dotnet build parameters (-p) don't work when joined by semicolon (;) in dotnet 6.0.400

Describe the bug

Using multiple MSBuild parameters joined by a semicolon in a dotnet build command don’t work anymore in dotnet 6.0.400.

To Reproduce

Executing the following command doesn’t work anymore:

dotnet build -p:propertyA=valueA;propertyB=valueB

But changing it to this does:

dotnet build -p:propertyA=valueA -p:propertyB=valueB

In my case, the command:

dotnet build -p:Version=1.1.1.1;AdditionalConstants=Beta

resulted in the following error:

Error NETSDK1018: Invalid NuGet version string: '1.1.1.1;AdditionalConstants=Beta'.

Exceptions (if any)

N/A

Further technical details

• Using dotnet version 6.0.400 (previously worked in version 6.0.302)
• Command being executed as part of an Azure DevOps build pipeline

[X-Celcius]

I would like to emphasize that this causes build failures from one day to another in Azure Pipelines because of the way the DotNetCoreCLI task runs the dotnet command. In our case we run dotnet using arguments like these:

- task: DotNetCoreCLI@2
  inputs:
    command: pack
    configuration: $(buildConfiguration)
    packagesToPack: '**/*.csproj'
    buildProperties: 'InformationalVersion=Foo'

And it fails because under the hood dotnet will be run using this argument:

dotnet pack [...] /p:Configuration=Release;InformationalVersion=Foo

Which since 6.0.400 will lead to the build configuration actually being Release;InformationalVersion=Foo instead of Release.

As you can see we don’t specify semicolons or commas anywhere and we don’t have a way to specify multiple -p options on the command line. I can see that this may need to be fixed in Azure Pipelines instead but I suspect this combination to lead to build failures all over the place.

can confirm this too. as a workaround i found out that comma (“,”) works as a separator, but semicolon (“;”) does not.

For us this breaks the “pack” task (and a few others) in Azure Devops Pipelines, as they use semicolon as a seperator (and we can’t change that)
