101 LINQ Examples in .NET Core

101 LINQ Examples is a great resource for those (like me) who are learning C# and LINQ.

However, I find the format of the examples a bit cumbersome: one solution file for each set of examples, lots of distracting files in the archive, a web interface that is hard to read. What I personally care about is just the bare minimum to read and run the code.

Therefore, as I am also learning my way through .NET Core and Visual Studio Code, I thought it would be nice to port those examples to .NET Core and package them in a repo that makes it easy to run them.

NOTE: I am not the author of the examples. I am just repackaging the existing samples to make sure they work under .NET Core and Visual Studio Code and changing them as little as possible to make them work.

Changes

Some minor changes were necessary to make the code samples work with .NET Core and Visual Studio Code.

Most of the changes were done using the script convert-samples.ps1, a primitive PowerShell script to do the heavy lifting.

The .cs files are the original files from the MSDN site. Changes made:

• uncomment all samples (done manually);
• read customers.xml as an EmbeddedResource (done via convert-samples.ps1).

All the .csproj files have been generated from scratch with the dotnet CLI by the convert-samples.ps1 script. Changes made from the bare-bones .csproj files when needed:

• add reference to customers.xml (done via script);
• add reference to the ObjectDumper project (manually);
• add reference to System.Data.DataSetExtensions (manually).

A separate project was created for the ObjectDumper library.

The manual changes could have been automated into the convert-samples.ps1 script, but at that point it was just simpler to do the changes manually rather than change and test the script again.

During the manual inspection, all projects were opened in Visual Studio Code, and the required files for building and executing the samples (.vscode/{launch,tasks}.json) were created automatically by the C# extension.

How to run the examples

TODO: add instructions to execute each example for each platform (Windows, Linux).

Visual Studio Code

With VSCode, having the .NET Core SDK and the C# extension installed, open the workspace file samples.code-workspace. It contains all projects, and will allow you to open all files from VSCode and run every project from the IDE itself, as opposed to opening the directory but not being able to automatically launch each separate example.
