Migration to Nuget V3

Home

Source: own resources, Authors: Agnieszka and Michał Komorowscy

Sometime ago I wrote a post about My struggels with GitHub, Subtrees and Nuget and Joseph suggested me another solution of my problem in the comments i.e. to switch to Nuget V3. A few days ago I finally found time to give it a try. I started by reading this tutorial/post written by Oren Novotny. It's really a good source of knowledge so I'll not describe the whole process again. However, I encountered 3 problems that weren't described and I'll briefly write about them.

Project.json vs Project.config

A new Nuget uses project.json file instead of the old project.config so I started with adding this new file to all projects. Then I moved packages from the old files to the new ones. In the next step I reloaded all the projects just to be sure that VS will see changes. After that I built the solution to see if it works and it worked. Finally, I made a commit and pushed my changes. And here comes a problem. In a few minutes I got an e-mail from my Azure (hosted) build controller that a build has just failed.

§ Error: C:\a\_tasks\NuGetInstaller_333b11bd-d341-40d9-afcf-b32d5ce6f23b\0.2.24\node_modules\nuget-task-common\NuGet\3.3.0\NuGet.exe failed with return code: 1
§ Packages failed to install

The source of a problem was apparently a conflict between project.config and project.json so I just removed the former from the projects.

Naming problem

It is not everything. The next problem looked in the following way:

Failed to resolve conflicts for .NETFramework,Version=v4.6 (win).
Unable to satisfy conflicting requests for 'MVVMLight': project/MVVMLight (>= 1.0.0) (via project/MVVMLight 1.0.0)
Unable to satisfy conflicting requests for 'CommonServiceLocator': CommonServiceLocator (>= 1.3.0) (via project/MVVMLight 1.0.0)
Unable to satisfy conflicting requests for 'MvvmLight': MvvmLight (>= 5.1.1) (via project/MVVMLight 1.0.0)...

This time the fix was also easy. Nuget V3 doesn't like if the projects in the solution have exactly the same names as packages! In my solution I had MVVMLight project which is my playground for MVVMLight package. I renamed in to MVVMLightTest.

Last but not the least

After migration to Nuget V3 I had to deal with one more problem and again I didn't observe it locally but only when building on Azure (hosted) build controller. In the build log I found the following error:

The OutputPath property is not set for project 'LanguageTrainer.csproj'. Please check to make sure that you have specified a valid combination of Configuration and Platform for this project. Configuration='Debug' Platform='x86'.

And it turned out that in some csproj files I had the following condition:

<Platform Condition=" '$(Platform)' == '' ">x86</Platform>

It says that if the platform is not specified for a given build then use x86. At the same time these csproj didn't contain configuration, including the problematic OutputPath, for x86. To fix a problem I simply changed x86 to AnyCPU.

Kolejny rok minął jak z bicza strzelił. Dużo się w nim działo, a w 2016 przynajmniej u mnie będzie się działo jeszcze więcej i z pewnością będzie ciekawie. Zanim to jednak nastąpi czekają nas Święta Bożego Narodzenia, czas odpoczynku, spotkań w rodzinnym gronie... i z tej okazji życzę Wam i Waszym bliskim wszystkiego dobrego.

Wszystkiego dobrego,

Another year passed like a whip shot. Much has happened in 2015 but even more is going to happen in 2016, at least in my case;) But it is still the future and now Christmas is right around the corner. It is a time of rest, meetings with the family... and on this occasion I wish You and Your relatives all the best.

Murphy's law in practice

The photo comes from MSI website

You must have heard about Murphy's law saying that Anything that can go wrong, will go wrong. We can also add ...at the least expected moment or ...at the worst possible time. Some time ago I had quite a busy evening i.e. I had to write some urgent e-mails etc. Everything was ok until suddenly my computer (MSI GE60 2OE, Windows 10) went crazy.

Did you know that about HTTP?

Recently, when answering a question on stackoverflow.com, I've learned an interesting thing about HTTP protocol. Actually currently it seems to be obvious to me ;) What I'm talking about? Well, initially I thought that if you send GET HTTP request in order to download a specific URL, then in a response you will get an entire page/file. In other words I thought that it's not possible to read the specific part of a page/file. However, it turned out that it's quite easy.

A screenshot comes from ShareLaTeX web site

Sometime ago I wrote that I was amazed when I found out that Nuget supports C++. Today, I was amazed even more, when I discovered ShareLaTeX web site. This site is simply great and I don't know how I've been living without it for such a long time.

I haven't been programming in C++ for a very long time and I didn't expect that I would do it professionally in the foreseeable future. However, the life has different plans ;) Recently, I've joined an extremely interesting project in the area of the computer vision. In a while I'll try to write something about it.

How to validate dynamic UI with JQuery?

Home

Source: own resources, Authors: Agnieszka and Michał Komorowscy

One of the most interesting task I developed some time ago was a library responsible for the generation of dynamic UI based on XML description in ASP.NET MVC application. The task was not trivial. The UI had to change based on the selections made by a user. I had to support many different types of controls, relations between them e.g. if we select the checkbox A then the text box B should be disabled and of course validations. In order to perform the client side validations I used jQuery Unobtrusive Validation library. I thought that it'll work just like that but it turned out that a dynamic UI may cause problems. Here is what I did.

3 reasons why I don't use strict mocks

Home

Source: own resources, Authors: Agnieszka and Michał Komorowscy

The majority, if not all, of mocking frameworks provides 2 types of mocks i.e. strict & loose. The difference between them is that the strict mocks will throw an exception if an unexpected (not configured /set up) method was called. I prefer to use loose mocks because with strict ones unit tests are fragile. Even the small change in the code can cause that unit tests will start failing. Secondly, if you need to set up many methods a test becomes less readable. Now, I can see one more reason.
