Resolving Paths To Server Relative Paths in .NET Code
ASP.NET Core automatically resolves 'virtual' paths in Razor pages or views to a site relative path.Note that more than likely you'd want to pass in all the parameters for base path, current page and host information, if you're processing the Url generically.In this post I've described a couple of helpers that do exactly that and even if you don't use these as is, they should give you the basis for resolving Urls in any Web scenario...

Inline Confirmations in JavaScript UI
What if you could instead use an inline UI to confirm an operation?In this post I describe a simple way you can use an inline UI to confirm an operation that can be easily implemented with a few lines of code and a couple of binding directives.I recently ran into an app that was using a nice and simple UI to handle confirmation of deletions by using a dual interface for the confirmation prompt - a button - to both start and confirm a delete operation.

Retrieving Images from the Clipboard Reliably in WPF Revisited
Recently however I started noticing some issues with some of my clipboard pasting code in Markdown Monster producing what appears to be corrupted images when displaying in an ImageSource control.What's happening in this code is that the image is copied to the clipboard from SnagIt and then picked up by the form when it loads from the clipboard and loaded into an Image control via an ImageSource bitmap.WPF Image Clipboard operations have been notoriously difficult to work with, but with this circuitous workaround described in this post, that first loads a bitmap and then an ImageSource from that, it's possible to load the vast majority of images reliably.

Comparing Raw ASP.NET Request Throughput across Versions: 8.0 to 9.0 Edition
Whenever a new release of .NET comes out I run a comparison test of versions using some of my own load testing tools and in this post I look at .NET 8.0 to 9.0.WebSurge can also run non-UI tests from the command line and these tests tend to be a bit more efficient as they don't have to deal with the overhead of even minimal UI updates.NET's performance trajectory has been on a steep upward trend and in this release that trajectory has leveled out a bit.

Back to Basics: Using the Parallel Library to Massively Boost Loop Performance
A few days ago I posted a quick note on X about a specific use case of using the Parallel library in .NET to massively optimize a link look up operation in Markdown Monster with very little code.The specific scenario I'm going to talk about is a Markdown link checker in my Markdown Monster editor that collects all links in a Markdown document and then checks those links - both local and online - for validity.However, after updating to using parallel code checking all links is drastically faster taking roughly the amount of time of the slowest link to process.

Getting the Current TabItem when the Tab is not selected in WPF
The icon tabs on the left can be accessed with the context menu even when the tab is not active.The key here is a small utility function WindowUtilities.FindAncestor<T>() which is used to walk up the control hierarchy to see if there's a matching control of the provided generic type - in this case a MetroTabItem (a TabItem subclass from MahApps.Metro)./// Finds a type of element in the parent chain of an element

Using Sql Server on Windows ARM
I recently picked up a Windows ARM device in the form of a Samsung Galaxy Book 4 with a SnapDragon X Elite chip.And yes, this is the SQL Server Express installer, but that installer also includes the LocalDb installer and so you go through most of the SQL Express setup - but without actually installing Express.If you want to do connect to the database in code you can do that with a connection string that looks like this:

Webcam randomly pausing in OBS, Discord, and websites - LSVCam and TikTok Studio
If you want to get rid of it, delete HKEY_CLASSES_ROOT\CLSID\{860BB310-5D01-11d0-BD3B-00A0C911CE86}\Instance\LSVCamThis is a regression that started recently for me, so it's my opinion that they are installing a virtual camera for their game streaming feature but they are doing it poorly.Nothing bad will happen if you delete the registry key BUT it'll show back up when you run TikTok Studio again.

Getting the ASP.NET Core Server Hosting Urls at Startup and in Requests
Today I was helping out a customer with their ASP.NET core application that wasn't starting up on a live server, hosted in IIS.So the task at hand is to get the Hosting Urls as part of the startup code in program.cs so that it can be written out as part of a start up banner as shown in Figure 1.You can also retrieve the host urls inside of a request by requesting a IServerAddressesFeature from an IServer instance and then requesting the feature and the addresses:

Back to Basics: Await a Task with a Timeout
Task natively doesn't have a way to provide for a timeout on a single task, and by default an await call on a task results in an indefinite wait on the task to complete which...If you prefer to retrieve the result, but deal with exceptions instead, you can use the TimeoutWithResult() method instead, which directly returns a result and throws an exception if the operation times out.I also added these functions into Westwind.Utilities in the AsyncUtils class as extension methods to Task.

Dealing with Platform Specific Classes and Methods in CrossPlatform .NET
If you deal with old .NET library code that is sprinkled with some Windows specific code in places you've likely run into places where the Windows specific code is throwing up unwanted compiler warnings. Sometimes that matters, but often times these warnings are annoyances as these methods are highly unlikely to get called from x-platform code. In this post I describe some annoyances, how you can work around them and eventually fix the issues without throwing everything out the window.

Mime Base64 is a Thing?
Ran into an old legacy application recently that required that attached data was preformatted to Mime Base64 which I never even heard of before. Turns out it's a 'url-safe' version of base64 that replaces certain characters that can be present in base64 with 'safe' characters. In this short post I show a small helper that handles several Base64 Mime operations.

ASP.NET Core Hosting Module with Shadow Copy Not Starting: Separate your Shadow Copy Folders!
I recently ran into a major failure related to Shadow Copying for an ASP.NET Web app on IIS which was caused by corruption of the Shadow Copy directories. The app starts with the dreaded white ANCM Error page and event log entries that point at missing application folders. It turns out that this is caused by interference of multiple applications using the same shadow copy folder. In this post I describe the problem and how to work around it.

Comparing Raw ASP.NET Request Throughput across Versions
When I set up a new machine I usually use a small ASP.NET test project to get a feel of performance of the machine and when that happens I also take a moment to compare performance across recent versions of .NET to see how things are improving - and improved they have.Both due to the new hardware I'm using but also ASP.NET continues to bump up performance in every new version that comes out.In this post I describe a simple project with minimal do nothing requests to test the ASP,.NET pipeline locally and how to test these request as well as discussing the results.

Reading Raw ASP.NET Request.Body Multiple Times
Some time ago I wrote about accessing raw request body content in ASP.NET Core which ended up being one of the most popular posts on this blog. But I failed to mention one major caveat: By default Request.Body can only be read once. In this post I discuss why frequently when you need raw Request.Body access you actually need to read the body more than once, and you can enable that functionality and deal with the caveats of doing so.

Working around the WPF ImageSource Blues
The WPF Image control and its ImageSource property can be problematic if you are loading a lot of images in a list. Depending on where you load images from, and how, you can very easily get bogged down with slow, blocking load operations, and memory leaks when the controls are released. In this post I describe a couple of specific problems I ran into loading a sizable list of images from files and show a few ways how to avoid the potential pitfalls related to ImageSource peculiarities.

Save Files With Elevated Permissions on UnauthorizedAccessException
If you have an application that generically allows you to edit and save files, you might on rare occasions need to save files in locations that where a regular user account does not have permissions to save. Rather than failing wouldn't it be nice to let the user know and optionally allow saving with elevated permissions? In this post I describe the workflow and implementation on how to do just that.

Caching your WebView Environment to manage multiple WebView2 Controls
I've been struggling with rare WebView initialization errors in one of my applications, that have been difficult to debug and track down. After a lot of trial and error I discovered that the problem is related to WebView Environment instantiations that might be stepping on each other. In this post I describe the problem and a solution that involves creating a single WebView Environment and reusing it for all WebView initialization.

IIS Error 500.19 with ASP.NET Core Application
Running on IIS locally is pretty rare, but if for some odd reason you decide to run IIS locally on your dev machine you might find yourself getting a 500.19 error which relates to an issue in the web.config configuration. The solution is simple enough: Make sure the ASP.NET Core Hosting Module is installed. In this post I describe in more detail what the problem is and why you need a seemingly superfluous extra install to get IIS and ASP.NET Core to cooperate on local dev machine.

A WPF Statusbar Control
Statusbar controls are boring, but because of the way that they are used there are a number of caveats like ensuring the UI updates even in linear code, allowing for timeouts of status messages and resetting to default, and to provide some visual clues to draw attention to the status messages displayed. In this post I talk about a custom status bar control and helper that make it super easy to use a new status bar control or attach additional functionality to an existing status bar.

Using WSL and Let's Encrypt to create Azure App Service SSL Wildcard Certificates
There are many let's encrypt automatic tools for azure but I also wanted to see if I could use certbot in wsl to generate a wildcard certificate for the azure Friday website and then upload the resulting certificates to azure app service. Azure app service ultimately needs a specific format called dot PFX that includes the full certificate path and all intermediates. Per the docs, App Service private certificates must meet the following requirements: Exported as a password-protected PFX file, encrypted using triple DES.Then upload the cert to the Certificates section of your App Service, under Bring Your Own Cert. Then under Custom Domains, click Update Binding and select the new cert (with the latest expiration date).

Getting .NET Library Projects to Output Dependent Assemblies
Recent .NET Core versions have changed how .NET Core Library projects output dependencies into the build folder. The new behavior doesn't output depdencies, unlike full framework .NET projects which always automatically dumped dependencies into the build output folder. This isn't a common requirement, but when you need it, the options are sufficiently obscure and this post discusses how you can make your dependencies output into the build folder

Removing the IIS Server Request Header from ASP.NET Core Apps (any version)
ASP.NET Core applications that run on IIS as InProcess output an Server name for IIS into the HTTP headers. If you want to remove the server header, you'll find that the process for IIS is different than for the internally created Kestrel header and you can't use the same approach to remove the header as with Kestrel applications. In this post I discuss why the header behaves differently in IIS and how to remove it regardless of ASP.NET version.

Sending and Receiving GMail Email Attachments that contain Code or Binaries
As a developer, you're likely to occasionally send an email with attachments that are either code or binary executable files either as straight files or in a zipped up collection of code or binary files.You'll find that you can't actually send certain types of files or even files embedded in archives and even encrypted archives as most mail servers these days scan file content both before sending and when receiving email.In this post I discuss what works and what doesn't and how you can work around those files that don't work.

Preventing iOS Textbox Auto Zooming and ViewPort Sizing
If you've build mobile Web applications that need to run on iOS Safari and on an iPhone you might have run into the problem of input fields 'auto-zooming' the display when the input field and popup keyboard get focus. The view zooms and doesn't return back to the unzoomed even after exiting the input field. In this post I describe why this happens in some scenarios, and a couple of ways you can work around this annoying iOS Web browser behavior.

Using Application Insights in .NET Desktop Applications
Using Application Insights with desktop applications isn't the most obvious operation, as App Insights has been primarily designed as a tool for providing logging, statitics and exception report for Web based applications. However, with a little bit of reworking it's actually quite straight forward to use Application Insights with Desktop applications and in this post I show you how I integrate App Insights in my WPF applications.

WkHtmlToPdf: Dealing with broken Url Encoded and Extended Character Links
WkHtmlToPdf is a commonly used tool to create PDF documents from HTML files or Urls. Unfortunately it's a bit cranky and one of the problems you can run into is that links that include URL encoding won't work in your output PDF. In this post I describe the problem and a hacky workaround to make broken PDF links work by hacking the HTML file prior to conversion.

Async Event Methods and preventDefault() in JavaScript
When using async events, it's important to understand how events work when called asynchronously.

A Button Only Date Picker and JavaScript Date Control Binding
The native date picker in HTML is a bit of a pain to work with as it's overly simplistic in features and how you have to assign and retrieve values from it.It also isn't customizable so if you need to build custom behavior like a button date popup that doesn't show the input control, you're out of luck.In this post I discuss the challenges of the HTML date picker control, provide small component to make binding values easier, and provide an example on how to create a button only date picker both with plain JavaScript and as a small Vue component.

Basic Windows Machine Hardware information from WMI for Exception Logging from .NET
When writing out error information for a desktop application to a log whether local or to a telmetry engine, it's useful to get some idea of what hardware the app is running on.WPF applications in particular can have odd behaviors that are related to hardware acceleration, running inside of a VM or particular video drivers.In this short post I show how you can get very basic machine and GPU information that provides information on these basic system stats that can prove useful to trackdown rare hardware related issues.

If you're doing local Web develop with multiple development tools you've probably run into a problem where you end up not being able to access a local site via unsecured `http://` requests and automatically get redirected to `https://` no matter what you try.If you don't have a certificate set up for the site you may not even be able to access the site at all.In this post I discuss how HSTS works and why it can be a problem for local development as well as how to clear out the HSTS cache or avoid using it locally.

I wrote a Tiny Virtual Operating System for a 300-level OS class in C# for college back in 2001 (?) and later moved it to VB.NET in 2002.This evening, as the children slept, I wanted to see if I could run the .NET Upgrade Assistant on this now 20 year old app and get it running on .NET 6. Let's start:$ upgrade-assistant upgrade .\TinyOS.sln-----------------------------------------------------------------------------------------------------------------Microsoft .NET Upgrade Assistant v0.3.256001+3c4e05c787f588e940fe73bfa78d7eedfe0190bdWe are interested in your feedback!

.NET 6 Hot Reload and "Refused to connect to ws: because it violates the Content Security Policy directive" because Web Sockets
DasBlog is a pretty large and cool app and we noticed immediately upon Mark upgrading it to .NET 6 that we were unable to use Hot Reload (via dotnet watch or from VS 2022).dotnet run will always assume it's in Development (you literally tell it to restore, build, and exec in one run command) if you run it.Don't ship your .NET SDK to your webserver and don't recompile the whole thing on startup in production!
