I know this is old, but since it is unanswered, it is a great way to test knowledge.

If you goto that link you will see the supported version of .net are 4.5.2, 4.6*, 4.6.1*
So it is possible 4.5.1 could work but not be supported. 

That would answer why updating your framework fixed the issue. 

The common location where `SharedPreferences` are stored in Android apps is:

    /data/data/&lt;package name&gt;/shared_prefs/&lt;filename.xml&gt;
User with root privileges can navigate to this location and can change its values.Need of protecting it is of much importance.

In how many ways we can encrypt whole `shared_pref&#39;s xml` file?

We all know that we can encrypt and save data in `shared_pref&#39;s xml` file, but that&#39;s not only 100% safe, so need to encrypt whole file with a key. Need help in knowing various ways to encrypt whole `xml` file. This is generic question, various encryption methods discussed as answers here can be helpful to all developers in securing apps.

I installed (Android studio 1.2 + SDK pack) for the first time, I created a test project with demo tab activity. I have not written a single line of code, everything has been generated by Android Studio

In fragment_main.xml the following problem occurs.

After upgrading the SDK to Azure Cloud Service Diagnostic 2.6, all the WAD trace logs started to look like this:

    EventName=&quot;FormattedMessageEvent&quot; FormattedMessage=&quot;Subscription {0} Already Created&quot; Argument0=&quot;sub2feature-staging&quot; TraceSource=&quot;w3wp.exe&quot;

Previously it use to just write out `&quot;Subscription sub2feature-staging Already Created&quot; TraceSource=&quot;w3wp.exe&quot;`

Is this something I can configure? Also looks like a lot of messages has moved from information to verbose. 

It&#39;s probably a combination of my log provider and some changes done in Azure Cloud Service Diagnostic 2.6.

I&#39;m spending my evenings evaluating Azure Service Fabric as a replacement for our current WebApps/CloudServices stack, and feel a little bit unsure about how to decide when services/actors with state should be stateful actors, and when they should be stateless actors with externally persisted state (Azure SQL, Azure Storage and DocumentDB). I know this is a fairly new product (to the general public at least), so there&#39;s probably not a lot of best practices in regards to this yet, but I&#39;ve read through most of the [documentation](http://azure.microsoft.com/en-us/documentation/services/service-fabric/) made available by Microsoft without finding a definite answer for this.

The current problem domain I&#39;m approaching is our event store; parts of our applications are based on event sourcing and CQRS, and I&#39;m evaluating how to move this event store over to the Service Fabric platform. The event store is going to contain a lot time series-data, and as it&#39;s our only source of truth for the data being persisted there it must be consistent, replicated and stored to some form of durable storage.

One way I have considered doing this is with stateful &quot;EventStream&quot; actor; each instance of an aggregate using event sourcing stores its events within an isolated stream. This means the stateful actor could keep track of all the events for its own stream, and I&#39;d have met my requirements as to how the data is stored (transactional, replicated and durable). However, some streams may grow very large (hundreds of thousands, if not millions, of events), and this is where I&#39;m starting to get unsure. Having an actor with a large amount of state will, I imagine, have impacts on the performance of the system when these large data models needs to be serialized to or deserialized from disk.

Another option is to keep these actors stateless, and have them just read their data from some external storage like Azure SQL - or just go with stateless services instead of actors.

Basically, when is the amount of state for an actor/service &quot;too much&quot; and you should start considering other ways of handling state?

Also, this section in the [Service Fabric Actors design pattern: Some anti-patterns](http://azure.microsoft.com/en-us/documentation/articles/service-fabric-reliable-actors-anti-patterns/) documentation leave me a little bit puzzled:

&gt; Treat Azure Service Fabric Actors as a transactional system. Azure Service Fabric Actors is not a two phase commit-based system offering ACID. If we do not implement the optional persistence, and the machine the actor is running on dies, its current state will go with it. The actor will be coming up on another node very fast, but unless we have implemented the backing persistence, the state will be gone. However, between leveraging retries, duplicate filtering, and/or idempotent design, you can achieve a high level of reliability and consistency.

What does &quot;if we do not implement the optional persistance&quot; indicate here? I was under the impression that as long as your transaction modifying the state succeeded, your data was persisted to durable storage and replicated to at least a subset of the replicas. This paragraph leaves me wondering if there are situations where state within my actors/services will get lost, and if this is something I need to handle myself. The impression I got from the stateful model in other parts of the documentation seems to counteract this statement.

Understanding when to use stateful services and when to rely on external persistence in Azure Service Fabric

The problem is that the Azure WebJobs SDK supports only public static methods as job entry-points which means there is no way of implementing constructor/property injection.

I am unable to find anything about this topic in official WebJobs SDK documentation/resources. The only solution that I came across is based on service locator (anti) pattern described on this post [here][1].

Is there a good way to use &quot;proper&quot; dependency injection for projects based on Azure WebJobs SDK?

Could you guide me on how to view the current roles/permissions granted to any database user in Azure SQL Database or in general for a MSSQL Server instance? 

I have this below query: 

    SELECT r.name role_principal_name, m.name AS member_principal_name
    FROM sys.database_role_members rm 
    JOIN sys.database_principals r

    WHERE r.name IN (&#39;loginmanager&#39;, &#39;dbmanager&#39;);

I further need to know what are the permissions granted to these roles &quot;loginmanager&quot; and &quot;dbmanager&quot;?

While &quot;googl&#39;ing&quot; and doing some research I were not able to find **any** serious/popular framework/sdk for scientific GPGPU-Computing and *OpenCL* on *AMD* hardware. Is there any literature and/or software I missed?

Especially I am interested in **deep learning**.

For all I know *deeplearning.net* recommends *NVIDIA* hardware and *CUDA* frameworks. Additionally all big deep learning frameworks I know, such as *Caffe*, *Theano*, *Torch*, *DL4J*, ... are focussed on *CUDA* and do not plan to support *OpenCL/AMD*.

Furthermore one can find plenty of scientific papers as well as corresponding literature for *CUDA* based deep learning tasks but nearly nothing for *OpenCL/AMD* based solutions.

Is there any chance that new or existing scientific frameworks will show up for *OpenCL/AMD* based solutions in 2015/16?

What is a good start for *deep learning* with *OpenCL/AMD*? Any literature? Tutorials? Miscellaneous sources?

OpenCL / AMD: Deep Learning

There are a **lot of system images** piling up on my disk in the android sdk folder. i hardly use the emulator. May be once in 6 months. Most of my development is directly on device. What i wanted to check was, **will removing the system images (at least for the old APIS i.e. &lt; 22) impact the development?**

**Also, the google apis folder seen below. Should i keep it for all versions or just the one in the latest suffice?**

I am trying to install Windows SDK for Windows 7 with .NET Framework 4 but when I open the setup I receive an error:

&gt; Some Windows SDK components require the RTM .NET Framework 4. Setup
&gt; detected a pre-release version of .NET Framework 4. If you continue
&gt; with Setup, these components will not be installed. If you want to
&gt; install these components, click Cancel, then install the .NET
&gt; Framework 4 from https://go.microsoft.com/fwlink/?LinkID=187668 and
&gt; then rerun Setup.
&gt; 
&gt; Click OK to continue.

When I went to install the .NET Framework 4 it appears a message saying that there is already the .NET Framework 4 on my PC:

&gt; The Microsoft .NET Framework 4 is already part of the operating
&gt; system. No need to install the .NET Framework 4 redistributable. [More
&gt; information][1].
&gt; 
&gt; An equal or higher version of the .NET Framework 4 has already been
&gt; installed on the computer.

I don&#39;t know what to do anymore. I am using Windows 10 Enterprise (x64).

Windows SDK 7.1 Setup failure

Totally new to iOS but I&#39;m currently trying to setup Google Analytics. I have followed [the SDK documentation][1] and everything went great until this step:

&gt; **Add the configuration file to your project**
&gt;
&gt;Drag the GoogleService-Info.plist file you just downloaded into the root of your Xcode project and add it to all targets.

It doesn&#39;t say anything on HOW to add it to all targets. Being new to Xcode and iOS in general, I&#39;m completely lost. Anyone with an answer for me?

Thanks!

How to add .plist file to all targets in Xcode?

My windows is on a 128GB ssd hard drive and its running out of space. the folder
`C:\Users\User\AppData\Local\Android` has 2 folders `android-sdk` and `sdk` folders that use about 30GB of space.

Is it possible to move these folders to an external hard drive?

If it is possible what changes should I make in the android studio?
