Installationof the .NET Framework may throw errors that are not listed in this article, but you might be able to try the following steps to fix those errors as well.Microsoft is releasing Out-of-band (OOB) updates for .NET Framework. .NET Framework Out-of-band update to address issues after installing the January 11, 2022 Windows update

This behavior can also be caused by a system administrator who configures the computer to use Windows Server Update Services (WSUS) instead of the Windows Update server for servicing. In this case, contact your system administrator and request that they enable the Specify settings for optional component installation and component repair Group Policy setting and configure the Alternate source file path value or select the Contact Windows Update directly to download repair content instead of Windows Server Update Services (WSUS) option.

Open the Specify settings for optional component installation and component repair Group Policy setting, and then select Enabled. The screenshot for this step is listed below.

If you want to specify an alternative source file, in the Alternate source file path box, specify a fully qualified path of a shared folder that contains the contents of the \sources\sxs folder from the installation media.

Or, specify a WIM file. To specify a WIM file as an alternative source file location, add the prefix WIM: to the path, and then add the index of the image that you want to use in the WIM file as a suffix.

To fix this problem, make sure that the full path of the source is correct (x:\sources\sxs) and that you have at least Read access to the location. To do this, try to access the source directly from the affected computer. Verify that the installation source contains a valid and complete set of files. If the problem persists, try to use a different installation source.

This error code occurs if an alternative installation source is not specified or is invalid and if the Specify settings for optional component installation and component repair Group Policy setting is configured to Never attempt to download payload from Windows Update.

To fix this problem, review the policy setting to determine whether it is appropriate for your environment. If you do not want to download feature payloads from Windows Update, consider configuring the Alternate source file path value in the Group policy setting.

You must be a member of the Administrators group to change Group Policy settings on the local computer. If the Group Policy settings for the computer that you want to manage are controlled at the domain level, contact your system administrator.

The following are examples of values that you can specify:

In Windows 10 and Windows Server 2012 R2, the .NET Framework 3.5 is a Feature on Demand. The metadata for Features on Demand is included. However, the binaries and other files associated with the feature are not included. When you enable a feature, Windows tries to contact Windows Update to download the missing information to install the feature. The network configuration and how computers are configured to install updates in the environment can affect this process. Therefore, you may encounter errors when you first install these features.

There are some questions here on stackoverflow about this topic, but even after reading all of them, I still wasn't able to make it work.I thought it would be useful to present an up-to-date, working solution about how to debug .NET framework source code.

Note: Since VS saves the path you entered for the source files, you can stop debugging or restart VS; it will work next time, too.Besides, you do not have to manually select any more source files within the framework, because the VS will use the source folder you entered and will search in source files there.

But some dll's are browseable, some not (through double clicking in Visual Studios stack view or context menu > goto source). This brought me to the assumption, that the .pdb itself must be the reason. If you look into a file which works (e.g. notepad), you see at beginning a list of strings with file pathes (source files). In files, which doesn't work, the files starting immediatelly with binary data.

In short: you have to search a dll version of your file (which you like to debug) which contains FULL DEBUG INFORMATION. This is also the reason why context menu disables "goto source".I'm replacing this file temporary in global assembly cache for time of debug. This works for me.

JetBrains dotPeek decompiles your actual .NET DLLs, then hosts a symbol server that you download symbols from in Visual Studio. After a pretty slow download, then a restart of VS, I was able to breakpoint and step into the code.

You can find the path to your .NET DLLs in the "Modules" window when debugging in VS. Enter this into dotPeek. Then Host Symbol server in dotPeek. Then add :33417 as your symbol server in VS symbol settings. then load those symbols. it takes a minute and a VS restart, but works.

Last week I needed to take a quick peek at some of the methods involved in the generation of JavaScript AJAX proxy scripts. I had a vague notion of what class and namespace was involved but not much else, and I needed to confirm how the URI was evaluated from base address. Much to my surprise I found a way browse the .NET Framework source code online (Reference Resource), it also has search and navigation which was, apparently, generated by the Roslyn complier (the new compiler is a gift that just keeps giving).

The next logical step is to go beyond simple searches and start directly debugging the Framework, this can be accomplished in Visual Studio with the following steps: Go to the Tools -> Options -> Debugging -> General menu Disable just my code Disable step over properties and operators Disable require source files to exactly match the original version Enable .NET framework source stepping Enable source server support Download .NET framework source code Of course if you prefer to use the search capabilities of Visual Studio (or NotePad++) you could simply download the versions of the .NET Framework you are interested in:

Error: 0x800f0906 The source files could not be downloaded. Use the "source" option to specify the location of the files that are required to restore the feature. For more information on specifying a source location, see =243077

Where D:\ is the mounted ISO or DVD drive. The only difference from yours is the /LimitAccess, but I believe that is the important part, as it prevents it from attempting to contact Windows Update or WSUS. For whatever reason, this aspect (contacting Windows Update) is totally broken for .NET Framework 3.5 on Windows 8/8.1 and Server 2012/2012R2 and will always cause it to fail.

There's lots of stuff on the internet on this and most of it was summarized in the answers here. We tried it all and none of it worked. Even when pointing at various copies of the sxs folder, it still would get a variation of the "source files not found" error.

My theory is that the install process was looking for source files that matched the current KBs on the server. I know there are other articles pointing to the removal of two particular KBs, but those did not show up in our list of installed patches.

When the DISM command skips the media specified by the /Source switch and goes looking for the files online, it means that the source files in the specified media is either corrupted or not applicable to your server (version mismatch).

Your DISM command isn't finding the required resources because it's checking for the source "online". Windows 6.2+ will (by default) check only with the update source server for component install/repair if an update source is specified for the Windows Update Service.

I have had the exact same issue. My resolution was to remove the server from Active Directory, Install .Net 3.5, then add back to AD. I'm sure it has to do with WSUS at some layer, but that solved it for us. We just make sure we install 3.5 on all servers before adding to the domain.

I followed the official guide and tried to build unreal engine from source code from github. However, when I tried to run the GenerateProjectFiles.bat, it throws the error:

C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\MSBuild\Current\Bin\Microsoft.Common.CurrentVersion.targe ts(1217,5): error MSB3644: The reference assemblies for .NETFramework,Version=v4.6.2 were not found. To resolve this, i nstall the Developer Pack (SDK/Targeting Pack) for this framework version or retarget your application. You can downloa d .NET Framework Developer Packs at [C:\Program Files\Unreal\UnrealEngine-4.25\En gine\Source\Programs\UnrealBuildTool\UnrealBuildTool.csproj]

I doubt I made a mistake in env variable setting. I notice that System variable about .net is C:\Program Files\dotnet\, but in there the sdk folder only contains 5.0404 (C:\Program Files\dotnet\sdk\5.0.404)

Update 21.05.2008 : A Windows Client which automatically does the steps required after download will be available in a few days. Please check out. Please send me whole your wishes in the project page, so i can include them in the next release.

The only thing you need to use this tools is having .NET Framework 3.5 RTM installed. With it, you can have whole the source code without any Visual Studio Product installed. If you are using Vista, please check that you are running under administrative permissions.
