Hi, What is the difference between: Starting a new thread Using TPL Using BackgroundWorker All of these create concurrency but what are the low-level differences between these? Do all 3 make threads anyway? Thanks ...
I have seen the Tuple introduced in .Net 4 but I am not able to imagine where can be it be used. We can always make a Custom class or Struct. Edit: I am looking for an example which can also be considered inside the bracket of best practices. ...
I just recently upgraded a VS2008/.NET 3.5 SP1 project to VS2010 and .NET 4. I have a post-build event which calls SGEN to generate the XmlSerializers assembly. Whenever I try to run it I get the following error. "C:\Program Files\Microsoft SDKs\Windows\v7.0A\bin\sgen.exe" /debug /force /verbose /c:"platform:x86" "C:\path\to\SomeAssemb...
I'm going nuts over what should be a very simple situation. In an ASP.NET MVC 2 app (not that I think this matters), I have an edit action which takes a very small entity and makes a few changes. The key portion (outside of error handling/security) looks like this: Todo t = Repository.GetTodoByID(todoID); UpdateModel(t); Repository.Sav...
Is it possible to do something like public class PriorityQueue<TValue, TPriority=int> where TPriority : IComparable (note the =int) ? Before you suggest it, yes, I know I can just add another line: public class PriorityQueue<TValue> : PriorityQueue<TValue, int> { } But I'm wondering if it's possible to do it as a param. ...
Hi all, I created a service which I now want to install to test. When running the setup program it prompts me to download and install .net fw 4.0, but I already have it installed. I did try to just install the file that I get pointed to (4.0 cliet), but not only does it still not work, it causes vs2010 to throw an unknown error and can'...
I created a service which I now want to install to test, I created a setup program from the templates in Visual Studio 2010. When running the setup program it prompts me to download and install .NET 4.0, but I already have it installed. I did try to just install the file that I get pointed to (4.0 client), but not only does it still not ...
I am having some issues involving Parallel for loops and adding to a List. The problem is, the same code may generate different output at different times. I have set up some test code below. In this code, I create a List of 10,000 int values. 1/10th of the values will be 0, 1/10th of the values will be 1, all the way up to 1/10th of the ...
I have been using DotNetBlogEngine for many years, and today my host (JodoHost.com) officially turned on support for .NET 4.0. I had them change my site from a 2.0 application to a 4.0 application and planned on recompiling the site if I had to. What I've noticed immediately is that the website loads tremendously faster on the first loa...
At face value, it would seem that object initializers present a problem for .net 4.0 "code contracts", where normally the invariant should be established by the time the object constructor is finished. Presumably, however, object-initializers require properties to be set after construction is complete. My question is if the invariants ...
I understand that the TPL uses work-stealing queues for its tasks when I execute things like Parallel.For and similar constructs. If I understand this correctly, the construct will spin up a number of tasks, where each will start processing items. If one of the tasks complete their allotted items, it will start stealing items from the o...
In a WPF application I defined default control styles in separate resource dictionaries (e.g. "ButtonStyle.xaml"), and added them as merged dictionaries to a resource dictionary named "ResDictionary.xaml". If I refer this "ResDictionary.xaml" as merged dictionary in my App.xaml, the default styles are not applied. However, if I refer th...
I am aware of the multitude of questions here as well as Raymond's excellent (as usual) post. However, since the algorithm to create GUIDs was changed apparently, I found it hard to get my hands on any up-to-date information. The MSDN seems to try and provide as few information as possible. What is known about how GUIDs are generated in...
For testing purposes, I installed .Net Framework 4 Client Profile. My tests ended and I was to uninstall it, in order to install .Net Framework 4 full. The uninstaller told me to uninstall .Net Framework 4 extended first. I've already found it and uninstalled, but the question remains: What is .Net Framework 4 extended? ...
I have 1.N threads writing to a .net 4.0 ConcurrentDictionary. I have another thread which fires every 5 seconds (settable in app.config) to enumerate the dictionary, and potentially remove some items. I want to halt the write operations during the enumeration. What would be the best primitive to synchronize these two operations. Any he...
I found that links: Microsoft .NET Framework 4 (Web Installer) Microsoft .NET Framework 4 (Standalone Installer) Microsoft .NET Framework 4 Client Profile (Standalone Installer) Note that (2) the size is 48.0 MB and the (3) the size is 41.0 MB. It's not the REAL .Net 4 Full Standalone. :( I want that installer in a usb pen drive bec...
The .Net 4 32 + 64 bit Full is 48.1 MB and the Client Profile is 41.0 MB. Why I will prefer install the Client Profile instead of the "Full Framework"? What difference there is in that packages? ...
I'm running into an issue upgrading a project to .Net 4.0...and having trouble finding any reason for the issue (or at least, the change causing it). Given the freshness of 4.0, not a lot of blogs out there for issues yet, so I'm hoping someone here has an idea. Preface: this is a Web Forms application, coming from 3.5 SP1 to 4.0. In ...
Hi, I have the need to make a call to the System.Xaml library in .NET 4.0. Is it possible to make a call to this library if your project is targeted to 3.5? ...
Hi, We are currently taking VS2010 for a testdrive and so far we are a little stumped with how it just won't cooperate with our existing Team Foundation Server 2008. We still have all our projects on .NET 3.5 and whenever we are now building a solution that contains a unit test project (which automatically builds in .NET 4.0) the TFS wo...
