I have developed my API with .NET 6 and locally, I can see all controllers working and using them through swagger.
However when I publish to IIS, I am getting 404 not found.
I also have install Net 6.0.1. Windows Server Hosting, Net Runtime 6.0.1 x64, Net Runtime 6.0.1 x86, ASP.NET Core 6.0.1 Shared Framework.
What could be the problem ?

Brian Li 16 Reputation points2022-07-01T23:32:50.717+00:00 I have same problem too, I try steps below
- remove
if (app.Environment.IsDevelopment())in Program.cs, make sure swagger can work on publish - run DEBUG, copy swagger url
/swagger/index.html - publish webapi
- create a website in IIS
- copy all publish files in to IIS website folder
- browse website, got 404
- paste swagger url, it's work
It's looks like webapi still running, but I dont know how to set swagger index to entrance
- remove

Steven Callahan 6 Reputation points2022-07-21T01:18:02.677+00:00 I had the exact same issue. Nothing worked (Angular SPA with NET 6). For the heck of it I commented out the 2 lines the instructions said to use and it started working!
app.UseSwaggerUI(options =>
{
// options.SwaggerEndpoint("/swagger/v1/swagger.json", "v1");
// options.RoutePrefix = String.Empty;
});Notice the comments on the options.* lines.

Bruce (SqlWork.com) 66,706 Reputation points2022-07-12T16:54:34.13+00:00 which problem?
swagger not enabled in prod -> remove if wrapper
core module not installed -> install
deployed as sub site -> use correct url: https://server/site/swaggerif you want swagger UI to be the default page:
app.UseSwagger(); app.UseSwaggerUI(o => { o.SwaggerEndpoint("/swagger/v1/swagger.json", "v1"); o.RoutePrefix = string.Empty; }); -

elerasoft 1 Reputation point2022-09-27T22:18:49.097+00:00 I am using Asp.net Core 6 and Angular. I lost 2 days solving this issue. I don't know why but when I use files in publish folder I faced this error. Using the published files in bin/release/net6.0 solved my problem.
