Build 2017 Day 1

This post is a recap of the first day of Build 2017



myTrades.Analytics - a netstandard compatible .NET technical analysis library written in F#

While working on a side project I created a netstandard compatible F# library, which basically calculates different technical analysis indicators for input data. This is mostly useful for technical stock analysis. I decided to open-source the library. This post shows what the library can do and how you can use it.



.csproj settings in asp.net core

This is an update of my project.json settings post, which describes the same settings in the new .csproj file



Hosting ASP.NET Core behind Apache on Ubuntu

The official documentation for hosting on Linux only describes how to host asp.net core apps behind nginx. Here is a short summary about the same for Apache.



Moving the blog

Finally, I managed to move my blog! This post is just a short technical summary about it.



Referencing an F# library from C# on .NET Core

Aaaand a post again, which will be deprecated at some point: currently using both F# and C# in a .net core solution is possible, but needs some workaround. Here I describe how you can do it



Working with .net core - my summary after 6 months with asp.net core on a side project

I have a side project which I started at the beginning of this year. One of the top goals of this project is to learn new things and i'm still at the beginning of this, but I already have many things working.



Migrating from ASP.net core RC1 to RC2 - Entity Framework Core

Asp.net core RC2 was officially released a few hours ago. I have a side-project, which I did not update until this point, so I developed on RC1-Update1 basis. The solution is a little bit bigger, it has 8 src projects and 4 tests. Most of them are C# projects and there are also a few F# projects. I have one project for the data access with Entity Framework Core.



project.json settings in asp.net core

Lately I work a lot with asp.net core and .net core. This is I think the biggest fully open source project Microsoft ever did and between RC1 and RC2 they made huge changes in the execution environment, which successfully confused me in many ways. But all this is fine, since it was only an RC1, and none said that the same stuff will RTM. In this post I summarize the most important settings in project.json



Talk: Monitoring with Application Insights

This weekend I co-presented a talk about monitoring Azure during the Global Azure Bootcamp in Linz. This post is the written form of my part from the talk.



How the evil System.Xml.Serialization.XmlSerializer class can bring down a server with 32Gb ram

This week I worked on some interesting stuff and fortunately there was a cool learning outcome from it, which is worth a blogpost, so I summarize it here.



Talk: The Universal Windows Platform - One codebase for Mobile, Desktop, IoT, Xbox, Hololens, etc.

On the 14th of January I gave a talk at a local technology meetup in Linz called Technologieplauscherl about the Universal Windows Platform. This post is the written form of the talk, which was intended for people who do not know UWP, but have a strong background in software development (and it's even better if you have some knowledge about C#/XAML based development).



Porting a Windows 8 Store app to the Universal Windows Platform

Back in 2012 I published a small Windows Store app called PassworWallet, which already had a few thousand downloads over the years and when Windows 10 came out the daily 5-10 downloads went up to 15-20, so I thought it's time to release an update, so the last days I updated it to UWP. This post summarizes the update process.



Test In-App Purchases in Windows Universal Apps (UWP)

The Universal Windows Platform supports In-App Purchases (IAP). This feature was already available in Windows 8/8.1, but I have not used it before. In this post I explain how you can debug an IAP in a UWP app.



GC Flavors in .NET

Since I have to look up these things at least twice a year I decided to write an extremely compressed summary about the GC types/settings in the .NET framework.



Asynchronous programming in C#

Two posts from me were published on the about:performance blog about the async capabilities of C#



Marshalling Jagged Arrays from CLR to Native

This week I was working on some stuff where I calculated some values in C# and I wanted to send it to a native C++ layer to use the values there. The data was originally stored in a Dictionary<int List<long>&gt;. As soon as I realised that I want to work with this in C++ it was clear that the Dictinary and the List classes are not the best, so instead of the C# collections I used a C# jagged array and I hoped that the framework can marshal it automatically. Well I was naive…



Classes with long initialization process implemented with Tasks in C#

When I work on Windows 8 Apps I often have the situation where I have a class which has a longer initialization process (e.g. deserialising some state from the file system, loading data over the network, make some complicated calculation, etc). One solution would be to write a public 'initialize' method and call it first to initilize the class. The problem with this is that it is…
