1.6.25: "IL Compilation failed" If Run From IDE But Succeeds When Published

warappa commented 3 years ago

Somehow IL compilation fails on property AssemblyString when run by IDE, but succeeds when published version is run by dotnet serve.

Workaround

Downgrade to LiveSharp 1.6.22 (don't forget to restart VS and rebuild solution).

Repo

https://github.com/warappa/RepoLiveSharpUpdateFailsWithMatBlazor/tree/dotnet5-debug-broken-publish-with-dotnet-serve-works

Prerequisites

Install dotnet tool install -g dotnet-serve
LiveSharp ~1.6.22 or~ 1.6.25
LiveSharp.Server 1.6.7

Steps

Clear %TEMP%\LiveSharp
Start LiveSharp.Server (1.6.7)
Checkout repo and open in VS 2019 (16.8.1 or 16.9.0 Preview 1)
Publish Client project
Navigate to published folder (RepoLiveSharpUpdateFailsWithMatBlazor\Client\bin\Debug\net5.0\browser-wasm\publish\wwwroot) and run dotnet serve -S -p 54328 - blazor app opens in browser
Set Client project as startup project in IDE
Run project (CTRL+F5) - blazor app opens in browser
In Index.razor change <h1>Hello, world!</h1> to <h1>Hello, update!</h1>
Update is reflected in browser of published version, but not in version started from the IDE - "IL Compilation failed" error is logged

Noteworthy

Does NOT happen with LiveSharp 1.6.22 (with VS restart after install)
SignalR payload (browser->LiveSharp.Server) different between publish-run and IDE-run version

warappa commented 3 years ago

Seems like this issue is releated to the Workspace\SolutionCache folder in the nuget package folder which was out of sync.

ionoy commented 3 years ago

Thank you for the detailed report! Can I assume that this issue was caused by stale SolutionCache then?

warappa commented 3 years ago

Hi @ionoy , I managed to retest it now. It is still reproduceable with this repo.

Steps:

Deleted C:\Users\<username>\.nuget\packages\livesharp\1.6.25
Deleted %Temp%\LiveSharp
Ran git clean -fdx on checked out repo
Opened in VS 2019 16.8.1
Rebuilt whole Solution
Set RepoLiveSharpUpdateFailsWithMatBlazor.Server as Startup Project
Start LiveSharp Server
Start project with F5
Changed h1 in Index.razor
WebSockets-Update received in Browser but then the forementioned exception is in LiveSharp server output (coming from browser as I suppose).

On the start-page I print all loaded Assemblies. It should start the list with "Anonymous ..." assembly, but it doesn't. (In this repo the JSON corruption does not happen)

ionoy commented 3 years ago

Can you try this build, please? I still get warning: ReflectionTypeLoadException Microsoft.JSInterop.WebAssembly... but otherwise it updates fine with the steps you provided above.

LiveSharp.1.6.26.zip

warappa commented 3 years ago

@ionoy Strange, I upgraded to 1.6.26 but no difference... Same output, exception etc. in F5 mode, but works if Client project is published and run by dotnet-serve.

Observation with both versions: As soon as I don't see Anonymously Hosted DynamicMethods Assembly I know it doesn't work.

In the working case it has a subset of assemblies loaded compared to the non-working case, but 2 assemblies are missing in the non-working case: Anonymously Hosted DynamicMethods Assembly and System.Net.Http.Json, Version=5.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51

This are the loaded assemblies when it's broken (F5 start):

EDIT

Wow. Trimming changes the LiveSharp dependencies to make it work. And: It switches the referenced assembly from netstandard to System.Private.CoreLib.

Tested publishing without trimming (<PropertyGroup>...<PublishTrimmed>false</PublishTrimmed>...</PropertyGroup>) and it does not work, publish with trimming and it works!

warappa commented 3 years ago

Sidenote: In the working case the Anonymously Hosted DynamicMethods Assembly assembly is loaded and visible in the list, regardless if a connection to LiveSharp.Server is already established or not (read: LiveSharp.Server does not matter).

Something prevents the Anonymously Hosted DynamicMethods Assembly assembly from loading in the first place.

Wild guess: Maybe the LiveSharp assembly causing the creation of Anonymously Hosted DynamicMethods Assembly requires netstandard2.1 or even net5.0 as target to successfully load.

Note: As far as I found out the netstandard2.1 assembly is just a reference assembly which references another reference assembly (System.Reflection.Emit 5.0.0.0) which then references System.Private.CoreLib. And the (trimmed) versions of LiveSharp in the working published directory are transformed to reference System.Private.CoreLib directly and works. I'm not saying this is the cause, but it seems like an interesting correlation...

When do you check for Anonymously Hosted DynamicMethods Assembly? I think it should be loaded when LiveSharp.Support.BlazorWASM creates interceptors for BuildRenderTree in BlazorUpdateHandler.Attach

Now I'm curious if 1) BlazorUpdateHandler was attached at all 2) OnMethodCallIntercepted was called with non-null Microsoft.AspNetCore.Components.ComponentBase (OnMethodCallIntercepted is implemented in LiveSharp.Runtime.dll LiveSharpRuntimeProxy if you want to dig deeper.

ionoy commented 3 years ago

By the way, are you using IIS Express in any of these tests?

Because I found: if it's there, it works ;) (As far as I understand it's where the Emit stuff ends up)

Now I'm curious if

BlazorUpdateHandler was attached at all

OnMethodCallIntercepted was called with non-null Microsoft.AspNetCore.Components.ComponentBase (OnMethodCallIntercepted is implemented in LiveSharp.Runtime.dll LiveSharpRuntimeProxy if you want to dig deeper.

How can I check that - in LiveSharp.dashboard.cs?

By the way, are you using IIS Express in any of these tests? I think I tried both, but will check that again.
