Extension to install \ deploy MSI as a build step in VSTS Release.

1. Allows to specify directory with MSI files

2. Allows to specify file mask to match (*.msi by default) if not all files from the directory should be installed

3. Allows to pass environment Variables as MSI properties. Variables are defined by Regex.
   Use cases:

• redefine TARGETDIR to install to an arbitrary folder
• pass property containing DB Connection String to be injected into Web.config during MSI installation

4. In case of installation failure:

• verbose log is attached to the Release, to see it click "Download all logs as zip"
• it will try to analyse log to find out the root cause and show it in the task output (this might not work on non-English versions of Windows)

Add step:

Configure step (note Regex in Advanced section):

Add env var to pass to MSI:

• Visual Studio Team Services - tested
• Team Foundation Server - not tested

• Escape double quotes (") in values of environment variables passed to MSI
