Specifying project name in msdeploy - msbuild

Question

I've got two web projects in one solution, and I'd like to deploy them both using msbuild and WebDeploy (this happens through a CI server).
Currently, I'm running a command line:
C:\ProjectFolder>msbuild <solution>.sln
/p:Configuration=<Release>
/p:OutputPath=bin
/p:DeployOnBuild=True
/p:DeployTarget=MSDeployPublish
/p:MsDeployServiceUrl=https://<ServerUrl:port>/msdeploy.axd
/p:username=<user>
/p:password=<password>
/p:AllowUntrustedCertificate=True
/p:DeployIisAppPath=<SiteName>
/p:MSDeployPublishMethod=WMSVC
This deploys one project, as expected. But how can I deploy the other as well? There's nowhere in this command line where I specified a project name - why did it choose one project to deploy over the other?
Ideally, I'd be able to deploy two project with the same command, something like
...
/p:Project=Project1
/p:DeployIisAppPath=<SiteName>/Project1
/p:Project=Project2
/p:DeployIisAppPath=<SiteName>/Project2
But I doubt that's possible. Alternatively, I just want to know how to specify a project name in the command line.

Answer 1

I think it would be better to divide the single call to three:
- Build sln;
- Deploy site1;
- Deploy site2;
msbuild.exe <solution>.sln
/p:Configuration=<Release>
/p:OutputPath=bin
msbuild.exe project1dir\proj1.csproj
/p:Configuration=<Release>
/p:OutputPath=<Path to common bin>
/p:DeployOnBuild=True
/p:DeployTarget=MSDeployPublish
/p:MsDeployServiceUrl=https://<ServerUrl:port>/msdeploy.axd
/p:username=<user>
/p:password=<password>
/p:AllowUntrustedCertificate=True
/p:DeployIisAppPath=<SiteName>/Project1
/p:MSDeployPublishMethod=WMSVC
msbuild.exe project1dir\proj2.csproj
/p:Configuration=<Release>
/p:OutputPath=<Path to common bin>
/p:DeployOnBuild=True
/p:DeployTarget=MSDeployPublish
/p:MsDeployServiceUrl=https://<ServerUrl:port>/msdeploy.axd
/p:username=<user>
/p:password=<password>
/p:AllowUntrustedCertificate=True
/p:DeployIisAppPath=<SiteName>/Project2
/p:MSDeployPublishMethod=WMSVC

If you run the command line from the projects' root folder(s), and don't specify a file to build, msbuild should automatically select the project in that folder.
This will require two separate command line calls, tho.
You can then build on this by building a batch file that cd's to each of the folders in turn and runs msbuild separately, or equally build your own proj file for msbuild that triggers each build.
Sorry I can't craft an example at the moment tho-on a phone!
