MVC MSBuild

1. Publish: Can't find the valid AspnetMergePath,,What you need is aspnet_merge.exe, tool that is distributed as part of Windows SDK. It's intended to precompile sites, so you can either turn that precompilation off, or install proper version of Windows SDK. 

2. Here how I worked it around at my system. Edit the Microsoft.Web.Publishing.AspNetConfigurationMerge.targets file and add the following line. Please make sure that the Microsoft SDK path is the same on your PC, if not then change it: <TargetFrameworkSDKToolsDirectory>C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bin\</TargetFrameworkSDKToolsDirectory>

3. msbuild *.sln /p:DeployOnBuild=true;PublishProfile=profile.pubxml
