Net 4 0 for iis 1 1
When multiple versions of ASP. NET are installed on a computer, the versions of ASP. NET are said to be running side-by-side. In this scenario, you must configure IIS to indicate which version of the ASP. NET ISAPI (aspnet_isapi.dll) should process a page in an ASP. NET application. In IIS 7.0, in both Classic and Integrated mode, the CLR version set for the application pool determines which version of ASP. NET and which associated version of the CLR are used to run an application. In IIS 6.0, a scriptmap is used to associate an application with a specific ASP. NET ISAPI version, and the ISAPI version in turn determines which version of the CLR is used to run the application. There are 32-bit and 64-bit versions of Aspnet_regiis.exe. For Windows Vista and Windows Server 2008, you can run the 32-bit version of the tool on a 64-bit installation of IIS. This lets you run mixed 32-bit and 64-bit worker processes on the same 64-bit system. The following table lists special cases and limitations that apply when you run the 32-bit version of the tool on a 64-bit version of IIS. IIS Version Special cases for 32-bit versions of Aspnet_regiis.exe6.0 You can run the 32-bit version of Aspnet_regiis.exe under a 64-bit IIS 6.0 installation on Windows Server 2003 with the following restrictions: The 32-bit version runs only if IIS has been set to run in 32-bit mode. The 64-bit version runs only if IIS has been set to run in 64-bit mode.7.0 On Windows Vista, Windows Server 2008, or Windows 7, when you run the 32-bit version of Aspnet_regiis.exe under IIS 7, the tool does not automatically set the enable32 Bit App On Win64 attribute of the application Pools element. On a default 64-bit operating system installation, with Windows on Windows 64 enabled, you can use 32-bit Aspnet_regiis.exe to configure IIS 7, but you will not be able to run any 32-bit applications, unless you explicitly change the.
First make sure you have IIS installed then perform the following steps: 1. Open your command prompt ( Windows + R) and type cmd and press ENTER You may need.
As previously announced, starting January 12, 2016 Microsoft will no longer provide security updates, technical support or hotfixes for. NET 4, 4.5, and frameworks. All other framework versions, including 3.5, 4.6 and, will be supported for the duration of their established lifecycle. The decision to end support for these versions will allow us to invest more resources towards improvements of the. NET Framework. What Does This Mean? You should ensure that a supported version of the. NET Framework is installed in your environment, on Windows desktops and servers. This includes Azure and other cloud service deployments. See more information on Azure deployments below. Applications targeting a. NET Framework version that is no longer supported will not need to retarget or recompile to a newer version as they can be run on a later. NET Framework version. The. NET Framework and higher versions have higher compatibility, provided by a newer feature called “quirking”. Quirking is a pattern in which a. NET Framework version maintains the semantics of earlier versions, while including updated implementations. The. NET runtime knows which of these semantics or quirks to execute depending on the. NET Framework version that the application targets. More information on migrating an application can be found on the Migration Guide to the. NET Framework MSDN article. The Azure team announced they will be making updated images available with the. NET Framework for guest OS families 2.x, 3.x and 4.x, in order to support apps deployed to Azure. These updated images were available for manual deployment in November and are available for automatic deployment in January. The Additional Information section below has more information.
