.VSIXMANIFEST File Extension

There is only one file type that uses the .VSIXMANIFEST extension:

VSIX Manifest

VSIX Manifest

File created by Microsoft Visual Studio, a SDK for the Windows system; contains metadata about the .VSIX file it resides in.

The Extension Manager in Visual Studio uses the data contained in the VSIXMANIFEST file to install the VSIX file on your machine.

The VSIXMANIFEST data appears in the following format:

<?xml version="1.0" encoding="utf-8"?>
<PackageManifest Version="1.0">
  <Metadata>...</Metadata>
  <InstallationTargets>...</InstallationTargets>
  <Dependencies>... </Dependencies>
  <Assets>... </Assets>
</PackageManifest>

NOTE: When using project templates in Visual Studio, the manifest is named source.extension.vsixmanifest but then appears as extension.vsixmanifest when built and residing in the VSIX file.
