Notes:

5 — Will be covered by #25675 in the Reuse web components topic.
7 — Document dotnet/maui#2532.
9 — Create a folder at aspnetcore/blazor/hybrid/security.
13 — Create a folder at blazor/hybrid/publish.Cross-link landing and general guidance. Cross-link out to the Blazor host and deploy overview, and cross-link to this Hybrid apps publish overview from there.

Additional Tasks

• In the Error handling topic for macOS with .NET MAUI dev tools, react to resolution of Blazor Hybrid Mac Catalyst Dev Tools not Supported maui#5561. Context at Blazor Hybrid dev tools topic #25384 (comment). UPDATE: This now has a dedicated issue at Mac Catalyst dev tools support #26039.
• To fix Keeping webviews up-to-date in deployed Blazor Hybrid apps #25453, un-comment the remarks in the topic. PR: [RC2] Keep WebViews current #25670

Process

Working in order down this list ...

• Thursday (2/10): General tutorials work for existing tutorials. This isn't directly related to Hybrid apps coverage outside of preparing for cross-links, but I'd like to get this resolved first. Blazor tutorial organization #24960
• Thursday-Thursday (2/10-2/17): PRs loaded for review as they're ready with GH and email pings for review.
  • PR 1 Blazor Hybrid PR1 #24965
    • Preview notice INCLUDE
    • Blazor Overview (blazor/index.md) update
    • Tooling topic Additional Resources cross-link to the Hybrid tutorials overview
    • Supported platforms update
    • Hosting models update
    • Hybrid Overview (blazor/hybrid/index.md)
    • Hybrid Tutorials folder and overview (placed on PR 1 to unblock the remaining PRs)
  • PR 2: .NET MAUI tutorial .NET MAUI Blazor tutorial (PR 2) #24977
  • PR 3: WinForms tutorial Blazor Hybrid WinForms tutorial (PR3) #24989
  • PR 4: WPF tutorial Blazor Hybrid WPF tutorial (PR 4) #25043
• Friday (2/18): no-loc update to add "Blazor Hybrid" Add Blazor Hybrid to no-loc metadata #25064

Notes

• All topics to receive a preview notice at the top.
• A 'Blazor Hybrid' column as already been added to the Blazor.Docs project for tracking work.
• Although final release is apparently 7.0, we'll version topics for 6.0 or later so that they'll show up during preview.
• Some overview topics, at least initially, may only contain minimal guidance. The main value of some of them is to provide a cross-link landing from other places around the doc set and for external links. I recommend their use and have included them where needed here.
• I defer on "contextual ToCs" but mention that whatever is done I recommend not breaking a reader's location in the ToC as they read and work down our ToC.
• After further reflection, especially along the lines of the prior bullet, I think Hybrid apps security and host/deploy content should be in the Hybrid node. Again, I seek to avoid readers losing their place and getting frustrated trying to figure out where they just were.
• Conforms to the plan for Blazor tutorial location (ToC and physical location) for the reasons discussed at Question on tutorial location for current and upcoming Blazor tutorials #24900.
• Samples
  • https://github.com/danroth27/BlazorWinForms
  • https://github.com/danroth27/BlazorHybridWpf (we're reacting to WPF app with BlazorWebView fails to compile the Razor components maui#3526 with an RCL workaround)
  • In the .NET MAUI repo: https://github.com/dotnet/maui/tree/main/src/BlazorWebView/samples

Additional remarks from the discussion

There's no formal name for using Blazor with WPF and WinForms. The ".NET MAUI Blazor app" name comes from the corresponding template name, but we don't have templates for using Blazor with WPF and WinForms. ".NET MAUI Blazor app" merely refers to a .NET MAUI app with at least one BlazorWebView control. We will avoid defining a name for Blazor-WPF and Blazor-WinForms for now and instead refer to the task, something such as, "Add a BlazorWebView to a {WPF|Windows Forms} app."

Hybrid apps use a blend of native and web technologies. A Blazor Hybrid app uses Blazor in a native client app. Razor components always run natively in the .NET process and render web UI to an embedded web view control using a local interop channel. WebAssembly isn't used at all in Hybrid apps.

There's no plan to add BlazorWebView articles to the WPF and Windows Forms doc sets. .NET MAUI is a bit different in that the BlazorWebView is built into the framework. .NET MAUI docs will link to the Blazor docs wherever appropriate.

Additional remarks for the content and tutorials

• .NET MAUI tutorial
  • Include instructions both for getting started using the .NET MAUI Blazor template and manually adding a BlazorWebView to an existing .NET MAUI app, similar to what we'll need to document for WPF & WinForms.
  • Getting started guidance on both Windows and non-Windows machines.
• WPF and WinForms tutorials: Go off of the sample apps.
• Blazor Hybrid overview: Check out the presentations (email) as a starting point.
