[Catalin]

Hello and welcome to our forums,

The steps you need to follow are presented above.

Here is what you need to do:

1. check whether .NET Core 3.1 SDK is installed or not. If not, install it using the following link:

.NET Core 3.1 SDK (v3.1.401) - Windows x64 Installer

2. after the installation, open a command prompt and copy paste the commands:

Code: Select all

cd C:\Program Files (x86)\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.8 Tools

and

Code: Select all

gacutil -i "c:\Program Files\dotnet\sdk\3.1.401\Sdks\Microsoft.NET.Sdk.WindowsDesktop\tools\net472\System.Numerics.Vectors.dll"

and

Code: Select all

gacutil -i "c:\Program Files\dotnet\sdk\3.1.401\Sdks\Microsoft.NET.Sdk.WindowsDesktop\tools\net472\System.Runtime.CompilerServices.Unsafe.dll"

Hope this helps!

Best regards,

Hello Henrik,

That specific error usually means that the product is already installed on the machine.

Therefore, you can skip the installation step and move on to the next step.

Failure adding assembly to the cache: The system cannot find the file specified.

- So I tried using version 3.1.414, but I still get the error trying to import a project.

[Catalin]

Hello Henrik,

Unfortunately, I can not say for sure why this is happening.

Could you please try to uninstall version 3.1.414 and then install the version 3.1.401, register those two components and retest this?

Additionally, are you receiving the exact same error as the previous users? Perhaps something is different in your scenario.

If possible, could you please forward me a screenshot of the error?

Best regards,

Hello Henrik,

Thank you for your followup on this!

Well, indeed the solution did not help, because you are facing another problem than the users above.

The error message states that the SDK "Microsoft.NET.Sdk.WindowsDesktop" could not be found. Could you please check whether this is installed on your machine or not?

The following Microsoft article might help:

.NET Project SDK overview

Hope this helps!

Hi Catalin,

Thx for your assistance.

Please let me know how to install SDK "Microsoft.NET.Sdk.WindowsDesktop"?
It's not installed, and I'm unable to locate it as a MS downloadable or component in VS installer.

[Catalin]

Hello Henrik,

You should be able to download it from here:

.NET/.NET Core

SDK.png (78.01 KiB) Viewed 18108 times

The current one is the 5.0 version. However, you may need to select the version according to what .NET your application is targetting.

Hope this helps!
