Using MSBuild.exe To Build A Simple Windows Phone 7 Project

I have a clean, Windows 7 x64 box setup to build and run Windows Phone 7 projects. I installed Windows Phone Developer Tools 7.0, January 2011 Update and Windows Phone Developer Tools Fix as per the MSDN App Hub page. My WP7 applications build fine in VisualStudio, yet when I try to use MSBuild.exe, even on the simplest Visual Studio project

c:\Windows\Microsfot.NET\Framework64\v4.0.30319\MSBuild.exe .\SimpleWP7.sln

I get the following errors (with added space between lines for readability)

... verbose.output ...

C:\Program Files (x86)\MSBuild\Microsoft\Silverlight for Phone\v4.0\Microsoft.Silverlight.Common.targets(185,9): error MSB4018: The "CompileXaml" task failed unexpectedly.\r [C:\Users\alasdair.mccall\vs_workspace\SimpleWP7\SimpleWP7\SimpleWP7.csproj]

What am I missing here? I have Silverlight 3 and 4 installed and I've installed everything as documented on the App Hub. Please let me know if there is any additional information required.

Cheers, Alasdair.

See second post: forums.create.msdn.com/forums/p/75679/460407.aspx#460407 Make sure you're using VS CMD prompt – keyboardP

I was using the wrong msbuild executable, I should have been using 

c:\Windows\Microsoft.NET\Framework\v4.0.30319\MSBuild.exe

I'm unsure why, on Windows 7 64bit I should've been using what appears to be msbuild for 32bit applications. Thanks to @keyboardP for directing me to Visual Studio command prompt which helped diagnose this.
