Bye MixRadio!

Today was my last day as a MixRadio employee.

After Microsoft completed the acquisition of the Nokia Devices & Services business, MixRadio and all of it’s employees became part of Microsoft.

However, a couple of weeks after that Microsoft started a full reorganization and decisions were quickly made to ensure MixRadio would become a separate entity.

So the only visible changes resulting from the acquisition are actually the company signs around the office, the “blue badges”, and the new email addresses… no other real integration ever happened for MixRadio, so I can’t actually say I felt like a Microsoft employee during this short period!

As a result of all this, plans have been made for the future of MixRadio as a new company that made me believe this is the right time for our paths to come apart.

During my time with the company, I was involved in almost every aspect of the MixRadio Windows Phone client development; every time I open the MixRadio 4.x client in my phone, I can’t help but to feel proud of what this team accomplished.

I wish the very best to MixRadio and all my colleagues in the upcoming future, and I’m sure to keep using MixRadio service as it is by far one of the best streaming music services available!

As for me, I will keep doing what I love, always related with development under Microsoft Technologies, but more to come on this over the next weeks…

Bye Nokia… Hello Microsoft!

The deal to transfer substantially all of the Nokia Devices & Services business to Microsoft has now officially been closed.

With it, I proudly become a Microsoft employee! 🙂

I will always cherish the moment I decided in moving to the UK to work for Nokia (even if that stopped any chance of receiving the Microsoft MVP award, but that’s another story!).

Nokia made me feel that I could actually make a difference with my work, and I truly appreciate the company for the opportunity!

I’ve been working with Microsoft technologies for more time than I can remember, both as a user and also as an IT professional, and I consider getting the “blue badge” as a giant career step for me!

In the present moment this doesn’t bring any significant changes: I’ll carry on working in the MixRadio apps here in Bristol, as I did until today!

Thank you Nokia, it’s been really fun… Hello Microsoft! 🙂

Error: Nuget.exe exited with code -1073741819

Lately I’ve been getting more and more this type of error from Nuget Package Restore when building my apps:

NuGet -1073741819 error

This seems to be a completely random issue with Nuget, as I see it happening with different projects, and sometimes not even happening at all!

Problem is that I work with some big/complex solutions that have a lot of projects, each one with it’s own packages.config file that can show this issue, so that sums up to a lot of failed builds!

There are actually a few open tickets about this in Codeplex, but given that this issue has been reported a while ago and so far it has not been solved, I thought on tackle this myself!

“If at first you don’t succeed, try and try again”

Following that motto, I thought on changing the Nuget Package Restore process so that it will retry a few times before aborting the build!

The easiest way I found to achieve this goal is just to change the .nuget\NuGet.targets file on the root of the solution. Inside this file, I found the following:

<Target Name="RestorePackages" DependsOnTargets="CheckPrerequisites">
    <Exec Command="$(RestoreCommand)"
          Condition="'$(OS)' != 'Windows_NT' And Exists('$(PackagesConfig)')" />

    <Exec Command="$(RestoreCommand)"
          Condition="'$(OS)' == 'Windows_NT' And Exists('$(PackagesConfig)')" />

Above you can see the MSBuild target that actually runs Nuget.exe, and so this is the one I will change to “fix” the issue.

This is my improved RestorePackages target:

<Target Name="RestorePackages" DependsOnTargets="CheckPrerequisites" Condition="Exists('$(PackagesConfig)')">
        <NugetLogStandardErrorAsError Condition="'$(OS)' == 'Windows_NT'">true</NugetLogStandardErrorAsError>
        <NugetLogStandardErrorAsError Condition="'$(OS)' != 'Windows_NT'">false</NugetLogStandardErrorAsError>

    <Exec Command="$(RestoreCommand)" LogStandardErrorAsError="$(NugetLogStandardErrorAsError)" IgnoreExitCode="True">
        <Output TaskParameter="ExitCode" PropertyName="ExitCode" />

    <Message Text="Error occurred, #1 retry..." Importance="High" Condition=" $(ExitCode) != 0 " />

    <Exec Command="$(RestoreCommand)" LogStandardErrorAsError="$(NugetLogStandardErrorAsError)" IgnoreExitCode="True" Condition=" $(ExitCode) != 0 ">
        <Output TaskParameter="ExitCode" PropertyName="ExitCode" />

    <Message Text="Error occurred, #2 and last retry..." Importance="High" Condition=" $(ExitCode) != 0 " />

    <Exec Command="$(RestoreCommand)" LogStandardErrorAsError="$(NugetLogStandardErrorAsError)" Condition=" $(ExitCode) != 0 " />

You can see three consecutive Exec tasks here, each one will run depending on the previous one exit code, and only the last one will actually abort the build.

What this means is that if Nuget fails, we will retry it two more times before aborting the build!

As you can see, this is not a proper fix for the issue, it just bypasses it… so I’m still waiting for a fix on this – and I’m now looking at you, Nuget dev team! 😉


My name is Pedro Lamas, I’m a Portuguese developer specialized in Microsoft Technologies, and this is my English blog for Windows and Windows Phone Development.

For a while this address was home for my Portuguese blog Nação do Cimbalino. Rest assure that the blog still exists, it just got moved to a new address!

I’ll be working to get the blog up and running in the next few days, so please bare with me.

I promise it will be worth it! 😉
