title: MSBUILD : error MSB1008: Only one project can be specified in teamcity
body: <p>I am trying to run MSBuild with TeamCity. </p>
  
  <p>I have a batch file and I pass into it parameters and the build works. When I try to run through TeamCity I get the error below</p>

  </code></pre>
  
  <p>In TeamCity my command line parameters field looks like
  <code>Configuration=Debug;DeployPath=E:\websites\umbraco\mysite;Environment=Dev;</code></p>
  
  <p>I did search on StackOverflow and people having similar issues mention ensuring no spaces in commandline parameters also my sln and proj files / pages do not have spaces.</p>
  
  <p>As I said when I run a batch file with those parameters it all works, however, TeamCity fails.</p>
