How to use workflow designer in elsa 2

[yariamirhossein]

I'm using elsa 2.0.0-preview6.1080, and I want to use workflow designer but I can't run it. Please help...
My startup.cs is like below :

`public void ConfigureServices(IServiceCollection services)
{
services.AddRazorPages();
services
.AddElsa(option => option.UsePersistence(conf => conf.UseSqlServer("Server=localhost;Database=WFTest01;User=sa;Password=Aa@123456;", IsolationLevel.ReadUncommitted)))
.AddHttpActivities()
.AddConsoleActivities()
.AddDataMigration()
.AddIndexProvider()
.AddWorkflowContextProvider()
.AddWorkflow()
.AddElsaApiEndpoints()
.AddElsaClient(conifgure =>
{
conifgure.ServerUrl = new Uri("https://localhost:44319/");
});

	}

	// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
	public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
	{
		if (env.IsDevelopment())
		{
			app.UseDeveloperExceptionPage();
		}
		else
		{
			app.UseExceptionHandler("/Error");

			app.UseHsts();
		}
		// Add HTTP activities middleware.
		app.UseHttpActivities();

		// Show welcome page if no routes matched any endpoints.
		//app.UseWelcomePage();


		app.UseHttpsRedirection();
		app.UseStaticFiles();
		app.UseRouting();

		app.UseEndpoints(endpoints =>
		{
			endpoints.MapRazorPages();
		});

		//app.UseEndpoints(endpoints => endpoints.MapControllers());


	}`

I don't know what extra configuration I should do or which url I should try to see designer.
thank you 👍

Elsa 2 has no designer at the moment (although it is currently under development).

The only way to use Elsa 2 preview as of this writing is by implementing them via code (see the samples directory)

Thank you so much for your response. 👍
Your new design is great 🥇

The original 2020 answer was correct for 2.0.0-preview6: there was no designer available in that preview yet.

For current Elsa, the visual designer lives in the separate elsa-studio repository rather than inside elsa-core. In the current Studio code, AddWorkflowsModule() wires in the workflows feature, default activity port providers, and AddWorkflowsDesigner() (elsa-studio/src/modules/Elsa.Studio.Workflows/Extensions/ServiceCollectionExtensions.cs:33-56), and the sample WASM host registers that module directly (elsa-studio/src/hosts/Elsa.Studio.Host.Wasm/Program.cs:92-105).

So for modern versions, the path is to run/use Elsa Studio (or one of the Studio hosts / embeddable components), not to look for a designer URL inside the old preview server setup shown in the original post.

Since the preview-era question was already answered and acknowledged by the original poster, I'm closing this discussion as resolved.
