Swagger.json is displayed but the UI not-CodePudding

I have ASP.Net 6.0 project and I have configured Swagger as follows:

services.AddSwaggerGen(c =>
{
    c.SwaggerDoc("v1", new OpenApiInfo {
        Title = "MyApi",
        Version = "v1"
    });
    c.CustomSchemaIds(x => x.FullName);
    c.ResolveConflictingActions(x => x.First());
});

and:

app.UseStaticFiles();

app.UseSwagger();
app.UseSwaggerUI(c =>
{
#if DEBUG
    c.SwaggerEndpoint("/swagger/v1/swagger.json", "MyAPI");
#else
    c.SwaggerEndpoint("/MyApp/swagger/v1/swagger.json", "MyAPI");
#endif
    c.RoutePrefix = string.Empty;
});

The swagger.json is being served from the correct endpoint. But the UI endpoint returns 404 Not Found.

What is the correct way to show the UI?

CodePudding user response：

After testing, I feel that this may be an option that needs to be optimized. Your code is correct, but now we encountered strange behavior.

So I analyzed, why does c.RoutePrefix = string.Empty; not take effect in VS2022 at startup? But when I directly access https://localhost:port, the function is normal.

This seems to be related to the settings in VS2022, so I found the settings below and found the settings for Url.

Then I delete the swagger value, and the issue was fixed.
