可以使用以下代码示例来解决此问题：

public class CustomRazorViewCompilerProvider : IViewCompilerProvider { private readonly ApplicationPartManager _partManager; private readonly Action _setupAction;

public CustomRazorViewCompilerProvider(ApplicationPartManager partManager, Action setupAction)
{
    _partManager = partManager;
    _setupAction = setupAction;
}

public CompilerCacheResult GetCompilerCacheResult(ActionContext context)
{
    var feature = new ViewsFeature();
    _partManager.PopulateFeature(feature);

    var razorFiles = feature.ViewDescriptors.Where(vd => vd.ViewAttribute?.GetType() == typeof(RazorViewAttribute)).ToList();

    var compiler = new Microsoft.AspNetCore.Mvc.Razor.Compilation.RazorViewCompiler(
        new CSharpCompilationProvider(),
        new RazorCompilationService(
            new DefaultRoslynCompilationService(),
            RazorTemplateEngineFactory.Create(setupAction => _setupAction(setupAction))),
        _partManager);

    return new CompilerCacheResult(
        compiler,
        razorFiles.Select(rf => new RazorFileInfo
        {
            FullTypeName = rf.FullName,
            RelativePath = rf.RelativePath,
            Hash = rf.Hash,
        }).ToList());
}

}

public class CustomMvcRazorMvcOptionsSetup : IConfigureOptions { public void Configure(MvcRazorMvcOptions options) { var provider = new CustomRazorViewCompilerProvider( options.PartManager, setupAction => { setupAction.SetBaseType(typeof(CustomMvcRazorPage<>)); setupAction.ConfigureClass((type, b) => b.Append($"[assembly:{nameof(RazorTargetAssemblyAttribute)}("{type.GetTypeInfo().Assembly.GetName().Name}")]")); } );

    options.ViewEngineOptions.ViewCompilerProvider = provider;
}

}

在Startup.cs中添加以下代码：

services.Configure(options => options.ConfigureMvcRazorMvcOptions(services)); services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_2).AddRazorPagesOptions(options => { options.Conventions.ConfigureFilter(new IgnoreAntiforgeryTokenAttribute()); }); 以上代码将自定义RazorViewCompilerProvider添加到ViewEngineOptions中，并配置了MvcRazorMvcOptions。通过在CustomRazorViewCompilerProvider中指定RazorCompileOptions，可以防止其他动态加载的Razor汇编未卸载。
