Install SharpShell by searching for 'SharpShell' in the NuGet package manager, or using the Package Manager Console:

PM > Install-Package SharpShell

The latest official packages are listed below:

All documentation is being moved to docs.

Some of the most useful guides are:

• Deploying SharpShell Servers

The following extensions are supported by SharpShell.

Shell Context Menus allow the context menus used in Windows Explorer to be customised.

Step by Step Tutorial on the CodeProject.

Shell Icon Handlers are DLLs that are registered in the system to customise the appearance of icons.

Step by Step Tutorial on the CodeProject.

Shell Info Tip Handlers are DLLs that are registered in the system to customise tooltips for items in the shell.

Step by Step Tutorial on the CodeProject.

Shell Drop Handlers are DLLs that are registered in the system to extend the drag and drop functionality in the Shell.

Step by Step Tutorial on the CodeProject.

Shell PreviewHandlers are dlls that can be registered in the system to allow you to create visually rich previews for items that are displayed directly in Windows Explorer.

Step by Step Tutorial on the CodeProject.

Shell Icon Overlay Handlers can be really useful. They let you display an icon overlay over shell objects to provide extra information. Programs like Dropbox use these overlays to show whether files are synchronised or not.

Step by Step Tutorial on the CodeProject.

Shell Thumbnail Handlers (or as they're sometimes known, Shell Thumbnail Providers) are COM servers that you can write to customise the appearance of the thumbnail icons in the Windows Shell.

Step by Step Tutorial on the CodeProject.

These are extensions that add extra pages to the property sheets shown for shell items such as files, network shares, folders and so on.

Documentation.

These are extensions which add custom functionality to the Windows Desktop or Task Bar.

Documentation

SharpShell is currently developed in Visual Studio 2017, and can be built using the Community Edition.

In order to maximize compatibility, we do not use the latest version of each SDK. The following components are needed:

• Windows Universal CRT SDK
• Windows 8.1 SDK
• .NET Core runtime
• Windows Universal C Runtime
• Microsoft Visual Studio 2017 Installer Projects
• Chocolatey (choco)

As long as the correct components have be installed for Visual Studio, you should be able to just open the main ./SharpShell/SharpShell.sln solution to build, test and run any of the code or samples.

You can also use the following scripts to run the processes:

These scripts will generate various artifacts which may be useful to review:

artifacts\
  \build
    \SharpNativeBridge    # 32/64 bit native binaries for the bridge.
    \SharpShell           # The SharpShell assembly.
  \tests                  # NUnit Test Reportsd
  \coverage               # Coverage Reports

Only assemblies and binaries which need to be copied into other projects are added to the artifacts/build folder. This makes chaining more complex dependencies manageable. The solution is fairly standard, but be aware that:

1. SharpShell depends on SharpNativeBridge
2. SharpNativeBridge should be built in x64 mode. When successful, the x64 build will trigger a x32 build, and both 32/64 bit binaries are copied to the artifacts/build/SharpNativeBridge folder.
3. SharpShell copies the latest native bridge binaries to its own NativeBridge folder - these are then embedded in the SharpShell assembly.
4. The SharpShell assembly is copied to artifacts/build/SharpShell folder after a successful build.
5. The SharpShell assembly is embedded in the ServerRegistrationManager binary. The assembly is copied from artifacts/build/SharpShell prior to the server registration manager build.

All of the above steps are automated, and will run whether a build is trigger from Visual Studio, the build.ps1 script or msbuild.

A detailed guide explaining how to configure and use logging for SharpShell is at:

./docs/logging/logging.md

You can also use the SharpShell-Easy-Log tool to quickly enable/disable logging options and view the logs realtime:

The tool is available at: github.com/ElektroStudios/SharpShell-Easy-Log

CI/CD is currently handled by AppVeyor. AppVeyor will:

1. Build the project
2. Run the tests
3. Create the core SharpShell NuGet Package
4. Publish the package to nuget.org if a version tag is pushed
5. Create a GitHub release with the package if a version tag is pushed

To create a release:

1. Update the version number in SharedAssemblyInfo.cs
2. Update the CHANGELOG.md
3. Create a new version tag, then push

AppVeyor will build and publish a new NuGet package and as long as a new semver tag is pushed.

If you've used SharpShell and would like to add a testimonial, just send me a message!

CmisSync, our Dropbox-like client for Enterprise Content Management servers, just switched to SharpShell, and we are extremely pleased with this library. Our previous custom-built Windows Explorer integration was buggy, unreliable and hard to maintain, and SharpShell is really rock-solid in comparison. The best part: It only took 2 days to integrate SharpShell into our software, testing and installer included. Thanks SharpShell!
