Failed to install Lync in Windows 8

When tried to install Lync in Windows 8 I faced error Another Installation Already in Progress (Although I didn't run previous installation). After some investigation I discovered I need to call setup as administrator.

But in Windows 8, right-clicking on a program in the Start screen won’t display Run as administrator option. While Run as administrator option is available when you right-click on a program shortcut on the desktop, the same option doesn’t appear when you right-click on program shortcut in the Start screen.

Step 1: Switch to the Metro Start screen and start typing the program’s name to see your program

Step 2: Right-click on the program name to see Advanced option.
Step 3: Click on Advanced and then select Run as administrator option.
After these steps, I can install Lync

How to Make ODP.NET 4.0 (64 bit) working on 64 bit machine

When you Install ODP.NET 64 bit and try to use it in Visual Studio 2010 and the project is of type ASP.NET Website. it give the error from the web.config file during compile time.

"Could not load file or assembly 'Oracle.DataAccess, Version=4.112.2.0, Culture=neutral, PublicKeyToken=89b483f429c47342' or one of its dependencies. The system cannot find the file specified"

The best possibility to handle this is to use the x86 version locally with Visual Studio and x64 version on the server with IIS. To do this you have to download both versions - copy one in folder lib\x86 and the other in lib\x64 After this you have to modify the project file(s) - visual studio supports conditional references. Add following section to your project file:

<PropertyGroup>      <ReferencesPath Condition=" '$(Platform)' == 'x86' ">..\Lib\x86</ReferencesPath>         <ReferencesPath Condition=" '$(Platform)' == 'x64' ">..\Lib\x64</ReferencesPath>       </PropertyGroup>

After this reference the odp.net assmebly like this:

<Reference ... processorArchitecture=$(Platform)">    <SpecificVersion>False</SpecificVersion>    <HintPath>$(ReferencesPath)\Oracle.DataAccess.dll</HintPath>              <Private>True</Private>   </Reference>

Tips Comment ASPNET Controls

Some times ASPNET Developer do mistake by commenting server controls
as html comment like below:
<!--<aspnet:TextBox runat="server" id="txt"/>

-->
This comment will affect only by rendering tags as commented html, but doesn't affect its server side events and validations. which
will cause many problems. It is displaying sensitive information, it is vulnerable to cross-site scripting,  failure in firing some scripts like script validation, unexpected behaviour of scripts, and render unwanted tags(affect the performance).

To ignore any of the above problems use server side:
<%--<aspnet:TextBox runat="server" id="txt"/>
