title: msbuild, defining Conditional Compilation Symbols
body: <p>I'm possibly just blind, but is there a command line to specify conditional compilation symbols in MSBUILD?</p>
  
  <p>I currently have this Line in my buildscript:</p>
  
  <pre><code>SET MSBUILD=C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\MSBuild.exe
  SET CONFIG=Debug
  %MSBUILD% /p:Configuration=%CONFIG% /p:OutputPath=..\..\output source\MyProject\MyProject.csproj
  </code></pre>
  
  <p>And I'd like to add a condition. In Visual Studio, i can just go into Project Properties => Build => Conditional compilation symbols, but I have not seen that option for msbuild?</p>
  
  <p>Bonus Karma if you know if I can completely override all symbols already specified in the .csproj files to make sure that only the conditionals from my Buildscript go in.</p>
