title: How to dynamically load properties from a file in MSBuild
body: <p>I'm scripting my build process, and I'd like to have a single MSBuild script that clones a repo, then includes properties in a file in that repo to drive the build. The only way I've found to include properties from another file is with the <code>Import</code> task, which can't reside inside a <code>Target</code>, so the file it's importing has to exist when MSBuild is initially invoked. Is there any way to run the <code>Import</code> after a target has run, or another way altogether to get properties out of a file in the middle of a build?</p>
