PowerShell Script to Create Visual Studio Project Template Extension Zip Issue

Question 1

I’m trying to write a PowerShell script to write a Visual Studio extension which will simply add a project template. Here is a trimmed down version of the script to demonstrate the problem:

# Add the assemblies

Add-Type -Assembly System.IO.Compression.FileSystem

# Create temporary directories for the zip archives

[System.IO.Directory]::CreateDirectory("Extension")
[System.IO.Directory]::CreateDirectory("Template")

# Build up the contents of the template file

$templateContent = "<?xml version=`"1.0`" encoding=`"utf-8`"?>`r`n"
$templateContent += "<VSTemplate Version=`"3.0.0`" Type=`"Project`" xmlns=`"http://schemas.microsoft.com/developer/vstemplate/2005`" xmlns:sdk=`"http://schemas.microsoft.com/developer/vstemplate-sdkextension/2010`">`r`n"

$templateContent += "    <TemplateContent>`r`n"
$templateContent += "        <Project File=`"MyExtension.csproj`" ReplaceParameters=`"true`"></Project>`r`n"
$templateContent += "    </TemplateContent>`r`n"
$templateContent += "</VSTemplate>"

# Save the template file

$templateContent | Out-File ([System.IO.Path]::Combine("Template", "MyExtension.vstemplate")) -Encoding "UTF8" -NoNewline

# Delete the temporary directories
[System.IO.Directory]::Delete(“Extension”, $true)
[System.IO.Directory]::Delete(“Template”, $true)

When I run the script it successfully produces a MyExtension.vsix file. When I execute that file it installs the extension but if I now open Visual Studio 2015 and create a new project the project template (C# -> Web) doesn’t exist.

However if you do the following steps then it works fine (make sure you have uninstalled the old extension first):

Rename the MyExtension.vsix file to MyExtension.zip and then extract to a directory
Go into that directory and select all the files, right click and select Send to Compressed Folder
Rename the generated zip file to MyExtension.vsix
Execute this file to install the extension

It’s taken me hours to even notice this scenario fixes the issue. However this is a hack and in the long run it’s going to become quite tedious. I was wondering if anyone knew how my PowerShell script can be changed to fix this.

Thanks

Question 2

For some reason, [System.IO.Compression.ZipFile]::CreateFromDirectory will not create a zip/vsix file that works correctly,
even though it will show as installed. The template does not show in the new project UI.

Use 7zip instead to create zip files.

While I tried to investigate this issue, I did not like that the code was not using fully qualified paths, and the strings were hard to look at. I refactored your code a bit.

Based on my testing, this now works as expected.
