I am aware of two methods of casting types to `IEnumerable` from an `Arraylist` in Linq and wondering in which cases to use them?

e.g

    IEnumerable&lt;string&gt; someCollection = arrayList.OfType&lt;string&gt;()

or

    IEnumerable&lt;string&gt; someCollection = arrayList.Cast&lt;string&gt;()

What is the difference between these two methods and where should I apply each case?

I have a page that when you press &#39;log out&#39; it will redirect to the `login.aspx` page which has a `Page_Load` method which calls `FormsAuthentication.SignOut()`.  

The master page displays the &#39;log out&#39; link in the top right of the screen and it displays it on the condition that `Page.User.Identity.IsAuthenticated` is `true`.  After stepping through the code however, this signout method doesn&#39;t automatically set `IsAuthenticated` to `false` which is quite annoying, any ideas?

Page.User.Identity.IsAuthenticated still true after FormsAuthentication.SignOut()

I have a website sitting on an IIS 7 server:

I would like to create several sub domains that looks like
**SUBDOMAIN1.example.COM**

I created an IIS website and I set the bindings to be
http, port 80, the ip address of my server, and SUBDOMAIN1.example.COM and the physical path to a folder under **example.COM**

I restarted my website and clicked on browse, the browser than opened with the address:
http://SUBDOMAIN1.example.COM

But the website doesn&#39;t show up.

Do I have to do something with the DNS?

I&#39;m trying to make my library exportable as a DLL but I&#39;m getting a lot of these warnings for one specific class that uses std::vector:

    template &lt;typename T&gt;
    class AGUI_CORE_DECLSPEC AguiEvent {
    	typedef void (*AguiCallbackFptr)(T arg, AguiWidget* sender);
    std::vector&lt;AguiCallbackFptr&gt; events;
    public:
    	void call(AguiWidget* sender, T arg) const;
    	void addHandler(AguiCallbackFptr proc);
    	void removeHandler(AguiCallbackFptr proc);
    	void removeHandler();
    	AguiEvent();
    };

I get warnings like these:

&gt; Warning	57	warning C4251:
&gt; &#39;AguiEvent&lt;T&gt;::events&#39; : class
&gt; &#39;std::vector&lt;_Ty&gt;&#39; needs to have
&gt; dll-interface to be used by clients of
&gt; class &#39;AguiEvent&lt;T&gt;&#39;

I tried to find how to do this properly but MSDN&#39;s documentation is very Windows Only, and I need this to be cross platform so that it only does MS specific stuff when AGUI_CORE_DECLSPEC is in fact defined.

What should I do to get rid of these warnings?

Thanks

I just copied an existing project to a brand new machine to start developing on it and have run into a problem with the version of one of my referenced assemblies (a telerik DLL as it happens).

The project originally referenced an older version of the assembly (lets call it v1.0.0.0).  My new machine has the latest version of the assembly installed, so I thought I&#39;d updated it (lets call the new version v2.0.0.0).

Now here&#39;s the problem: If I copy the old v1.0.0.0 dll to the project folder and add it as a reference, the web site launches without a problem.  If I delete that reference (and also delete the old DLL from my system) and add the new version (v2.0.0.0), the page shows the following exception:

&gt; Could not load file or assembly
&gt; &#39;XXXXXX, Version=1.0.0.0,
&gt; Culture=neutral,
&gt; PublicKeyToken=121fae78165ba3d4&#39; or
&gt; one of its dependencies. The located
&gt; assembly&#39;s manifest definition does
&gt; not match the assembly reference.
&gt; (Exception from HRESULT: 0x80131040)

Clearly, the code is looking for the out of date version and can&#39;t find it.  But why?

I greped the solution folder for that version number and couldn&#39;t find a single reference.  I double checked the text of the .csproj file and found the version correctly shows the latest version and the HintPath correctly shows the path to the new DLL.  Furthermore, because I didn&#39;t install the old DLL on the system it doesn&#39;t show up in my GAC (though v2.0.0.0 does, as expected).

I then enabled the fusion log viewer to try to figure out why it&#39;s looking for that old version, but no luck:

    Assembly Load Trace: The following information can be helpful to determine why the assembly &#39;XXXXXX, Version=1.0.0.0, Culture=neutral, PublicKeyToken=121fae78165ba3d4&#39; could not be loaded.

All it says it that it starts by looking for that old assembly.  I have tried to find a solution online and saw this similar [SO question][1], but it seems to be the exact opposite of my problem.  That questioner&#39;s program was finding the wrong DLL instead of the referenced one.  Whereas my problem is that the program is mysteriously looking for the wrong DLL and unable to find it when the right one can be found locally in the bin folder and in the GAC.

Why is mine looking for the old version?  Where else can I search to find this bad reference?

.Net picking wrong referenced assembly version

In my project I&#39;m using some third-party libraries. I include them using the references folder in Visual Studio.

But where should I save the DLL files? They are referenced from a path in the file system, but it would be nice if I can include it into the project. But how?

I have a DLL file. How can I view the functions in that DLL?

How to view DLL functions?

Whenever I tried to copy 4 files into my bin folder, after stopping the main service, I am getting an error with one file (TexteDll). The error is:

    Cannot copy TexteDll: The requested operation cannot be performed on a file 
    with a user-mapped section open

It may be due to some system locking. Or perhaps another process is using this DLL. When I googled, I found that rebooting the system may resolve this.

Can anybody suggest a cause or solution for this? I inspected the properties of TexteDll (general, version, security, etc). Everything appears normal.
