IIS | Ruby dsl for IIS management

I've updated Visual Studio 2022 to 17.1.0 recently and I now have this weird error, but not on every project (on only one up to now). I've tested other projects and they still work fine.

But this one project won't publish to IIS. It builds/runs locally, it can publish to a Folder profile, and a previous version is working in IIS.

It's a .NET 6.0 web api project.

In the Output window I can see these 2 errors:

My new Macbook Pro running on an M1 Max (ARM) chip just came in. I installed Parallels and Windows 11 Preview for ARM, and Visual Studio installs / launches / builds my solution beautifully. Unfortunately the turn windows features on or off dialog doesn't have the option for installing IIS, and others have posted that this is not supported in Windows 11 for ARM.

Our dev team runs multiple ASP.NET Core 3.1 websites locally under IIS using subdomains, e.g.: https://auth-dev.mydomain.com, https://web-dev.mydomain.com, https://webapi-dev.mydomain.com. This was easy to set up in IIS using the bindings dialog, I could specify for port 443 (https) to use a certain subdomain and our dev SSL certificate.

Now I need to figure out how to make this work on Windows 11 ARM. Developing on an inferior non-Macbook Pro laptop doesn't seem like a great solution for .NET devs, I have to assume others with M1 chip Macbook Pros have run into this same issue. What are my options?

I first started looking into using IIS Express, but it seems like every website has to run on a different port, whereas I need them all to run on port 80 (just with different subdomains.) I'd be fine with them running on different ports if there was a way to forward those various ports to the subdomains, but it doesn't seem like the windows HOSTS file supports that.

I also looked into using the Apache web server for Windows, but I read somewhere that it doesn't support running ASP.NET Core apps.

I've searched several SO posts and haven't found what I'm looking for. It might exists but might be fairly old enough to not show up for me. I found a post (Nginx rewrite: add trailing slash, preserve anchors and query strings) so close to what I need, but it's regex solution does not work for URL Rewrite for IIS, unless I'm doing it wrong.

Problem

I'm trying to add a forward slash / to the end of my url paths while also preserving any existing for query strings ? and anchors #.

Desired Solution

Basically, here's the desired results to each problem:

I have an ASP.Net Webforms website running in IIS on a Windows Server. Also on this server is the SQL server.

Everything has been working fine with the site but now I am seeing issues with using a DataAdapter to fill a table.

So here is some code, please note it's just basic outline of code as actual code contains confidential information.

We have a Web API (.NET Core 5) which passes the request on to another remote Web API.

The Web API grabs some cookies from the incoming request and appends them to the outgoing request.

Normally this works fine and we see the request cookies arriving at the remote Web API.

But when multiple requests are sent simultaneously, the cookies from one incoming request are somehow leaking over into the outgoing request of another.

This even happens when using totally separate users and totally separate browsers.

Things I've tried and confirmed:

• The code which copies the cookies from incoming request to outgoing request works perfectly fine. In fact even when the cookies appearing on the remote API are "leaked", my custom logging suggests it still worked as expected

• I can see the expected/leaky request cookie on the remote Web API (in its raw IIS logs), so it can't be the remote API adding it to the request in its pipeline.

• Added logging to the HttpClient call but can't see the unexpected cookies being sent.

• This doesn't happen locally

• My feeling is something is happening in HttpClient somehow??

• UPDATE 1 I added logging to CopyCookieHandler and it only gets created once and reused by all requests

• UPDATE 2 I just read that HttpMessageHandler instances results in CookieContainer objects being shared...which may possible explain this... https://docs.microsoft.com/en-us/aspnet/core/fundamentals/http-requests?view=aspnetcore-5.0#cookies

The first API has this setup to use HttpClient:

Using an existing .NET 5 MVC Web App, I attempted to upgrade to .NET 6, but encountered this error. I am also using IIS for Windows Authentication--now setup in .NET 6 as "profiles" under Properties -> Debug -> hyperlink (Open debug launch profiles UI). I also included the newer "Microsoft.AspNetCore.Authentication.Negotiate" Nuget package (and associated code) to handle the newer Windows Authentication library.

When the web app launches, I get the following error:

An unhandled exception occurred while processing the request.

InvalidOperationException: Cannot find compilation library location for package 'System.Security.Cryptography.Pkcs'

Microsoft.Extensions.DependencyModel.CompilationLibrary.ResolveReferencePaths(ICompilationAssemblyResolver resolver, List assemblies) Microsoft.Extensions.DependencyModel.CompilationLibrary.ResolveReferencePaths() Microsoft.AspNetCore.Mvc.ApplicationParts.AssemblyPartExtensions+<>c.b__0_0(CompilationLibrary library) System.Linq.Enumerable+SelectManySingleSelectorIterator.MoveNext()

...

Microsoft.AspNetCore.Diagnostics.DeveloperExceptionPageMiddleware.Invoke(HttpContext context)

This does NOT go away if I add the package listed: System.Security.Cryptography.Pkcs

I have installed the relatively fresh Visual Studio 2022 on a Windows installation. The work I do often requires administrative privileges (local IIS). To do this I have two users, one 'normal' account that is logged in to Windows and one administrator account. When starting VS2022 with the administrator account, an error keeps coming. It happens especially during debugging and it reads as follows:

We are having difficulties choosing a load balancing solution (Load Balancer, Application Gateway, Traffic Manager, Front Door) for IIS websites on Azure VMs. The simple use case when there are 2 identical sites is covered well – just use Azure Load Balancer or Application Gateway. However, in cases when we would like to update websites and test those updates, we encounter limitation of load balancing solutions.

For example, if we would like to update IIS websites on VM1 and test those updates, the strategy would be:

• Point a load balancer to VM2.
• Update IIS website on VM1
• Test the changes
• If all tests are passed then point the load balancer to VM1 only, while we update VM2.
• Point the load balancer to both VMs

We would like to know what is the best solution for directing traffic to only one VM. So far, we only see one option – removing a VM from backend address pool then returning it back and repeating the process for other VMs. Surely, there must be a better way to direct 100% of traffic to only one (or to specific VMs), right?

Update:

We ended up blocking the connection between VMs and Load Balancer by creating Network Security Group rule with Deny action on Service Tag Load Balancer. Once we want that particular VM to be accessible again we switch the NSG rule from Deny to Allow.

The downside of this approach is that it takes 1-3 minutes for the changes to take an effect. Continuous Delivery with Azure Load Balancer

If anybody can think of a faster (or instantaneous) solution for this, please let me know.

I have a busy ASP.NET 5 Core app (thousands of requests per second) that uses SQL Server. Recently we decided to try to switch some hot code paths to async database access and... the app didn't even start. I get this error:

The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached.

And I see the number of threads in the thread pool growing to 40... 50... 100...

The code pattern we use is fairly simple:
