To build a specific target of a specific project in a solution
At the command line, type MSBuild.exe <SolutionName>.sln, where <SolutionName> corresponds to the file name of the solution that contains the target that you want to execute.
Specify the target after the /t switch in the format ProjectName:TargetName.
The following example executes the Rebuild target of the NotInSolutionFolder project, and then executes the Clean target of the InSolutionFolder project, which is located in the NewFolder solution folder.
