Istalling .NET Framework 3.5(inlcudes 2.0 and 3.0) in windows 8

If the above solution dint work, the user is incited to ask the administrator for reconfiguring the system to use Windows Update instead of WSUS. To do so, a Windows 8(8.1) DVD needs to be inserted and specified guidelines need to be followed.
  • Insert a Windows 8 installation disc in CD/DVD Drive
  • Open Start Screen
  • Type ‘cmd’ to conduct a new Search
  • Locate Command Prompt, Right Click and choose ‘Run as Administrator’
  • In the black screen of Command Prompt, type
  • Dism /online /enable-feature /featurename:NetFx3 /All /Source:D:\sources\sxs/LimitAccess”
  • Press Enter key

generate machine key in asp.net

Generate a Machine Key (IIS 7)

1 out of 5 rated this helpful Rate this topic
Applies To: Windows 7, Windows Server 2008, Windows Server 2008 R2, Windows Vista
Machine keys protect Forms authentication cookie data and page-level view state data. They also verify out-of-process session state identification. ASP.NET uses the following types of machine keys:
validation key computes a Message Authentication Code (MAC) to confirm the integrity of the data. This key is appended to either the Forms authentication cookie or the view state for a specific page.
decryption key is used to encrypt and decrypt Forms authentication tickets and view state.

Prerequisites

For information about the levels at which you can perform this procedure, and the modules, handlers, and permissions that are required to perform this procedure, see Machine Keys Feature Requirements (IIS 7).
Exceptions to feature requirements
  • None

To generate machine keys

You can perform this procedure by using the user interface (UI), by editing configuration files directly, or by writing WMI scripts.

User Interface

To Use the UI

  1. Open IIS Manager and navigate to the level you want to manage. For information about opening IIS Manager, see Open IIS Manager (IIS 7). For information about navigating to locations in the UI, see Navigation in IIS Manager (IIS 7).
  2. In Features View, right-click Machine Key, and then click Open Feature.
  3. On the Machine Key page, select an encryption method from the Encryption method drop-down list. The default encryption method is SHA1.
  4. Choose a decryption method from the Decryption method drop-down list. The default decryption method is Auto.
  5. Optionally, configure settings for validation and decryption keys.
  6. In the Actions pane, click Generate Keys, and then click Apply.

Configuration

The procedure in this topic affects the following configuration elements:
  • <machineKey> element, defined in the Machine.config file.
For more information about IIS 7 configuration, see IIS 7.0: IIS Settings Schema on MSDN.

WMI

Use the following WMI classes, methods, or properties to perform this procedure:
  • MachineKeySection class. Keys are generated by setting properties, so no method is needed.)
For more information about WMI and IIS, see Windows Management Instrumentation (WMI) in IIS 7. For more information about the classes, methods, or properties associated with this procedure, see the IIS 7.0 Beta: IIS WMI Provider Reference on the MSDN site.

Cannot Add Reference To CrystalDecisions DLLS On VS 2010

Cannot add reference to CrystalDecisions.Shared, CrystalDecisions.ReportSource, CrystalDecisions.CrystalReports.Engine on VS 2010
I recently came across this situation where I had to print a report using crystal and VS2010
I had designed the report using Crystal Reports Designer. My task was to print the report on the click of the print button on my Win Form application.
First of all,Crystal doesn’t ship with VS 2010, you need to download and install this free exe from SAP Business Objects website
In the correct scenario , one can add the reference to to CrystalDecisions.Shared , CrystalDecisions.ReportSource, CrystalDecisions.CrystalReports.Engine using  Add Reference -> .NET tab .
However in my case I wasn’t seeing these dlls .
I tried adding them manually using browse and navigating to C:\Program Files\SAP BusinessObjects\Crystal Reports for .NET Framework 4.0\Common\SAP BusinessObjectsEnterpriseXI 4.0\win32_x86\dotnet
But I was tsill getting the reference error. After googling for some time I stumbled on the following page :
And following the discussion, I clicked on my Project Properties and Changed my target platform to .NET Framework 4 from .NET Framework 4 Client Profile.
