Adding Property Stops Updates #104

Closed warappa closed 1 year ago

warappa commented 3 years ago

Problem

If I add a property to my razor file the updates breaks.

Repo

https://github.com/warappa/RepoLiveSharpUpdateFailsWithMatBlazor/tree/add-property-breaks-updates Branch: add-property-breaks-updates

Prerequisites

Steps

  1. Deleted C:\Users\<username>\.nuget\packages\livesharp\1.6.33
  2. Deleted %Temp%\LiveSharp
  3. Ran git clean -fdx on checked out repo
  4. Opened in VS 2019 16.8.1
  5. Rebuilt whole Solution
  6. Set RepoLiveSharpUpdateFailsWithMatBlazor.Server as Startup Project
  7. Start LiveSharp Server
  8. Start project with CTRL+F5
  9. In Index.razor under AssemblyString insert public string Test { get; set; } and save
  10. Exception is shown in output of LiveSharp.Server (see below)
  11. No further change is reflected in the browser app

Without this tiny change i.e. duplicating SurveyPrompt or removing SurveyPrompt works flawlessly.

Extra

If you use the steps above and instead of adding Test property you replace the whole page with the following content, you get an IL Compilation failed error:

I think they are releated so I post those 2 issues together.

This issues cause my work on my regular project to be really "difficult" if you understand what I mean :)

ionoy commented 3 years ago

OK, it seems like the issue is fixed. I had to do a pretty major rewrite, which honestly was a long time coming.

Here is a build you can try: LiveSharp.1.6.34.zip

Thanks @ionoy !

Same with adding a parameter and starting to use it in another component.

  1. Create a new component
  2. Use it in another component
  3. Add a parameter in the child component (created in step 1.)
  4. Use the parameter in the parent component.
[Parameter] public string Name {get;set;}
crit: Microsoft.AspNetCore.Components.WebAssembly.Rendering.WebAssemblyRenderer[100]
      Unhandled exception rendering component: Object of type 'Append.Blazor.Components.Component1' does not have a property matching the name 'Middlename'.

Afterwards the livesharp crashes:

dpozimski commented 3 years ago

have the same issue too, livesharp works on C# classes (wasm), however when I switch to razor files and my file contains @click=(args => SomeAction()) hot reload stops work

warappa commented 3 years ago

@dpozimski It looks like this issue i had lately: https://github.com/OYIon/LiveSharp/issues/117

Solution: Update to version 2.0.13 (only available in Gitter chat https://gitter.im/LiveSharp/lobby). Don't forget to update the server tool also - 2.0.6 I think.
