Building a scheduled task in ASP.NET Core/Standard 2.0

In this post, we’ll look at writing a simple system for scheduling tasks in ASP.NET Core 2.0. That’s quite a big claim, so I want to add a disclaimer: this system is mainly meant to populate data in our application’s cache in the background, although it can probably be used for other things as well. It builds on the... Read more »

Automatically strong name signing NuGet packages

Some developers prefer to strong name sign their assemblies. Signing them also means that the dependencies that are consumed must be signed. Not all third-party dependencies are signed, though, for example when consuming packages from NuGet. Some are signed, some are unsigned, and the only way to know is when at com... Read more »

Speeding up ASP.NET vNext package restore

TL;DR: If you have multiple NuGet feeds configured on your machine, it may be worth to do some tweaking in the NuGet.config file shipping with your project.

Custom media types for ASP.NET Web API versioning

There is a raging discussion on the interwebs on whether to version API’s by using their URL or by using a custom media type. Some argue that doing it in the URL breaks REST (since a different URL is a different resource while versions don’t necessarily mean a new resource is available). While I still fe... Read more »

From API key to user with ASP.NET Web API

ASP.NET Web API is a great tool to build an API with. Or as my buddy Kristof Rennen (and the French) always say: “it makes you ‘api”. One of the things I like a lot is the fact that you can do very powerful things that you know and love from the ASP.NET MVC stack, like, for example, using filter at... Read more »

Tracking API usage with Google Analytics

So you have an API. Congratulations! You should have one. But how do you track who uses it, what client software they use and so on? You may be logging API calls yourself. You may be relying on services like Apigee.com who make you pay (for a great service, though!). Being cheap, we thought about another approach fo... Read more »

Using SignalR to broadcast a slide deck

Last week, I’ve discussed Techniques for real-time client-server communication on the web (SignalR to the rescue).

Windows Azure Accelerator for Web Roles

One of the questions I often get around Windows Azure is: “Is Windows Azure interesting for me?”. It’s a tough one, because most of the time when someone asks that question they currently already have a server somewhere that hosts 100 websites. In the full-fledged Windows Azure model, that would mean 100 x 2 (we wan... Read more »

Delegate feed privileges to other users on MyGet

Using dynamic WCF service routes

For a demo I am working on, I’m creating an OData feed. This OData feed is in essence a WCF service which is activated using System.ServiceModel.Activation.ServiceRoute.

Using operator overloads for concatenating file system paths in CSharp

The past few days, I’ve been working on some cross-platform C# code. In this code, I needed to build a path to a file, by concatenating folder names. As you may know the path separator on Windows and Linux operating systems are different: one has a backward slash (\), the other has a forward slash (/). Read more »

Building a scheduled task in ASP.NET Core/Standard 2.0

In this post, we’ll look at writing a simple system for scheduling tasks in ASP.NET Core 2.0. That’s quite a big claim, so I want to add a disclaimer: this system is mainly meant to populate data in our application’s cache in the background, although it can probably be used for other things as well. It builds on the... Read more »

Making string validation faster by not using a regular expression. A story.

A while back, we were performance profiling an application and noticed a big performance bottleneck while mapping objects using AutoMapper. Mapping is of course somewhat expensive, but the numbers we were seeing were way higher than expected: mapping was ridiculously slow! And “just mapping” was not a good explanati... Read more »

Extending .NET CLI with custom tools - dotnet init initializes your NuGet package

A few weeks back, .NET Core 1.1 was released (and a boatload of related tools such as Visual Studio 2017. For .NET Core projects, a big breaking change was introduced: the project format is no longer project.json but good old .csproj. That’s a little bit of a lie: the .csproj is actually an entirely new, simplified ... Read more »

Using dotPeek to figure out why IIS crashed

Exploring memory allocation and strings

A while back, I wrote about making code allocate less memory (go read it now if you haven’t). In that post, we saw how the Garbage Collector works and how it decides to keep objects around in memory or reclaim them. There’s one specific type we never touched on in that post: strings. Why would we? They look like val... Read more »

Making .NET code less allocatey - Allocations and the Garbage Collector

The .NET Garbage Collector (GC) is quite cool. In combination with the runtime’s virtual memory, it helps providing our applications with virtually unlimited memory, by reclaiming memory that is no longer in use and making it available to our code again. By doing so, it also takes away the burden of having to alloca... Read more »

Building NuGet (.NET Core) using Atlassian Bitbucket Pipelines

A while back, I signed up for the beta of Bitbucket Pipelines, a new continuous integration service from Atlassian, built into Bitbucket.

Someone broke the Internet! Or why you may want to mirror your dependencies…

This week’s topic: someone broke the Internet! Wait, break the Internet? Well, sort ... Read more »

Disabling session affinity in Azure App Service Web Apps (Websites)

In one of our production systems, we’re using Azure Websites to host a back-end web API. It runs on several machines and benefits from the automatic load balancing we get on Azure Websites.

Not enough space on the disk - Azure Cloud Services

I have been using Microsoft Azure Cloud Services since PDC 2008 when it was first announced. Ever since, I’ve been a huge fan of “cloud services”, the cattle VMs in the cloud that are stateless. In all those years, I have never seen this error, until yesterday: There is not enough space on the disk.at System.IO.__... Read more »

Replaying IIS request logs using Apache JMeter

How would you validate a new API is compatible with an old API? While upgrading frameworks in a web application we’re building, that was exactly the question we were asking ourselves. Sure, we could write synthetic tests on each endpoint, but is that representative? Users typically find insane better ways to test an... Read more »

Domain Routing and resolving current tenant with ASP.NET MVC 6 / ASP.NET 5

So you’re building a multi-tenant application.

Could not load file or assembly… NuGet Assembly Redirects

When working in larger projects, you will sometimes encounter errors similar to this one: “Could not load file or assembly 'Newtonsoft.Json, Version=4.5.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed' or one of its dependencies. The system cannot find the file specified.” Or how about this one? “System.IO.Fil... Read more »

Automatically strong name signing NuGet packages

Some developers prefer to strong name sign their assemblies. Signing them also means that the dependencies that are consumed must be signed. Not all third-party dependencies are signed, though, for example when consuming packages from NuGet. Some are signed, some are unsigned, and the only way to know is when at com... Read more »

Optimizing calls to Azure storage using Fiddler

NuGet Configuration File inheritance is awesome

One way to remove friction from using NuGet in multiple projects is by making use of NuGet Configuration File inheritance, probably the awesomest unknown feature in there.

Throttling ASP.NET Web API calls

Many API’s out there, such as GitHub’s API, have a concept called “rate limiting” or “throttling” in place. Rate limiting is used to prevent clients from issuing too many requests over a short amount of time to your API. For example, we can limit anonymous API clients to a maximum... Read more »

Custom media types for ASP.NET Web API versioning

There is a raging discussion on the interwebs on whether to version API’s by using their URL or by using a custom media type. Some argue that doing it in the URL breaks REST (since a different URL is a different resource while versions don’t necessarily mean a new resource is available). While I still fe... Read more »

From API key to user with ASP.NET Web API

ASP.NET Web API is a great tool to build an API with. Or as my buddy Kristof Rennen (and the French) always say: “it makes you ‘api”.

Tweaking Windows Azure Web Sites

A while ago, I was at a customer who wanted to run his own WebDAV server (using www.sabredav.org) on Windows Azure Web Sites.

Domain based routing with ASP.NET Web API

Imagine you are building an API which is “multi-tenant”: the domain name defines the tenant or customer name and should be passed as a route value to your API. An example would be http://customer1.mydomain.com/api/v1/users/1. Customer 2 can use the same API, using http://customer2.mydomain.com/api/v1/use... Read more »

Use NuGet Package Restore to avoid pushing assemblies to Windows Azure Websites

Windows Azure Websites allows you to publish a web site in ASP.NET, PHP, Node, … to Windows Azure by simply pushing your source code to a TFS or Git repository.

Protecting Windows Azure Web and Worker roles from malware

Most IT administrators will install some sort of virus scanner on your precious servers.

Tracking API usage with Google Analytics

So you have an API. Congratulations! You should have one. But how do you track who uses it, what client software they use and so on? You may be logging API calls yourself.

Techniques for real-time client-server communication on the web (SignalR to the rescue)

When building web applications, you often face the fact that HTTP, the foundation of the web, is a request/response protocol.

Publishing symbol packages for a MyGet feed

Ever since NuGet 1.2, there is a great way for NuGet package authors to let their users debug into the package’s binaries.

Why MyGet uses Windows Azure

Recently one of the Tweeps following me started fooling around and hit one of my sweet spots: Windows Azure.

And funny because we already have that featur... Read more »

Windows Azure Accelerator for Web Roles

One of the questions I often get around Windows Azure is: “Is Windows Azure interesting for me?”.

In the full-fledged Windows Azure model, that would mean 100 x 2 (we wan... Read more »

Using dynamic WCF service routes

For a demo I am working on, I’m creating an OData feed. This OData feed is in essence a WCF service which is activated using System.ServiceModel.Activation.ServiceRoute.
