CompilerFeatures.Register(builder);conditionally adds features depending on the language version. What version do you have set inconfigCompilerFeatures.Register(builder);根据语言版本有条件地添加功能。你设置config了什么版本
RazorLanguageVersion.Latest.
var config = RazorConfiguration.Create(
RazorLanguageVersion.Latest,
configurationName: "Blazor",
extensions: Array.Empty<RazorExtension>());
_projectEngine = RazorProjectEngine.Create(config, fileSystem, builder =>
{
builder.SetRootNamespace(options.RootNamespace);
builder.AddDefaultImports(options.DefaultImports);
CompilerFeatures.Register(builder);
builder.Features.Add(new CompilationTagHelperFeature());
builder.Features.Add(new DefaultMetadataReferenceFeature
{
References = _references
});
});And amazingly, for Blazor components, events can be handled correctly:

11 months ago I have found the reason, @using Microsoft.AspNetCore.Components.Web must be added to the default import, or appear in the code like this:
+ @using Microsoft.AspNetCore.Components.Web
<h1>Counter</h1>
<p role="status">Current count: @currentCount</p>
<button class="btn btn-primary" @onclick="IncrementCount">Click me</button>
@code {
private int currentCount = 0;
private void IncrementCount()
{
currentCount++;
}
}

3 months ago I have another problem. I'm using similar code as the author, specifically this: https://github.com/MudBlazor/TryMudBlazor/blob/main/src/Try.Core/CompilationService.cs
However, the new bindings @bind:get, @bind:set, @bind:after do not work.
<h1>Bind Get Set Examples</h1>
<h2>Elements</h2>
<input type="text" @bind:get="text" @bind:set="(value) => { text = value; }" />
<input type="text" @bind:get="text" @bind:set="Set" />
<input type="text" @bind:get="text" @bind:set="SetAsync" />
@text
@code {
private string text = "test";
private void Set(string value)
{
text = value;
}
private Task SetAsync(string value)
{
text = value;
return Task.CompletedTask;
}
}The issue is that while the code compiles, the bindings do not work. However, it works fine in a normal Blazor project. Does anyone have an idea of what might be missing? All the necessary using statements seem to be in place and the library versions are the latest.

I see that the ComponentBindLoweringPass is added, which I believe is responsible for that feature. This makes me even more confused about why it doesn't work.
Hi, I try using Microsoft.CodeAnalysis.Razor compiles Razor code, but it does not take effect for native element events. What is the reason for this?
the RazorProjectEngine:
razor source:
the generate c# code:
and the Rendered results:
