寻找无名的特质
首先创建一个空的Web 项目：dotnet new web -n "ElsaQuickstarts.Server.DashboardAndServer"
进入这个项目目录，安装程序包：
dotnet add package Elsa
dotnet add package Elsa.Activities.Http
dotnet add package Elsa.Activities.Temporal.Quartz
dotnet add package Elsa.Persistence.EntityFramework.Sqlite
dotnet add package Elsa.Server.Api
dotnet add package Elsa.Designer.Components.Web
打开program.cs文件，修改代码如下：
using Elsa;
using Elsa.Persistence.EntityFramework.Core.Extensions;
using Elsa.Persistence.EntityFramework.Sqlite;
var builder = WebApplication.CreateBuilder(args);
var elsaSection = builder.Configuration.GetSection("Elsa");
// Elsa services.
builder.Services
.AddElsa(elsa => elsa
.UseEntityFrameworkPersistence(ef => ef.UseSqlite())
.AddConsoleActivities()
.AddHttpActivities(elsaSection.GetSection("Server").Bind)
.AddQuartzTemporalActivities()
.AddWorkflowsFrom<Startup>()
);
// Elsa API endpoints.
builder.Services.AddElsaApiEndpoints();
// For Dashboard.
builder.Services.AddRazorPages();
var app = builder.Build();
if (builder.Environment.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
app
.UseStaticFiles() // For Dashboard.
.UseHttpActivities()
.UseRouting()
.UseEndpoints(endpoints =>
{
// Elsa API Endpoints are implemented as regular ASP.NET Core API controllers.
endpoints.MapControllers();
// For Dashboard.
endpoints.MapFallbackToPage("/_Host");
});
app.Run();
修改appsettings.json文件：
{
"Elsa": {
"Server": {
"BaseUrl": "https://localhost:5001"
}
}
}
创建Pages目录，增加_Host.cshtml文件，修改页面代码如下：
@page "/"
@{
var serverUrl = $"{Request.Scheme}://{Request.Host}";
}
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8"/>
<meta name="viewport" content="width=device-width, initial-scale=1.0"/>
<title>Elsa Workflows</title>

<link rel="stylesheet" href="/_content/Elsa.Designer.Components.Web/elsa-workflows-studio/assets/fonts/inter/inter.css">
<link rel="stylesheet" href="/_content/Elsa.Designer.Components.Web/elsa-workflows-studio/elsa-workflows-studio.css">
<script src="/_content/Elsa.Designer.Components.Web/monaco-editor/min/vs/loader.js"></script>
<script type="module" src="/_content/Elsa.Designer.Components.Web/elsa-workflows-studio/elsa-workflows-studio.esm.js"></script>
</head>
<body>
<elsa-studio-root server-url="@serverUrl" monaco-lib-path="_content/Elsa.Designer.Components.Web/monaco-editor/min">
<elsa-studio-dashboard></elsa-studio-dashboard>
</elsa-studio-root>
</body>
</html>
运行项目，可以创建编辑流程了。
