Environment: VS 2019 w/ all latest updates.
Installed Telerik UI For Blazor through Progress Control Panel.
Attempting to create new Telerik Blazor solution, or add new Telerik Blazor project to existing solution, yields the following error:
NU1101 Unable to find package Telerik.UI.for.Blazor. No packages exist with this id in source(s): Local Packages, Microsoft Visual Studio Offline Packages, nuget.org
Restarted VS as well as machine, same error.
Instructions on how to resolve would be appreciated.

Hello Michael,
From the list of feeds where VS looked for our package, it looks like the Telerik feed through which our UI for Blazor package is distributed, is not add on the machine.
Here's how to add it: https://docs.telerik.com/blazor-ui/installation/nuget
Alternatively, you can use a local feed: https://docs.telerik.com/blazor-ui/installation/zip
You can find more details on what you need to get things running in this article: https://docs.telerik.com/blazor-ui/getting-started/what-you-need
If you prefer tutorials, here are two:
- WASM apps: https://docs.telerik.com/blazor-ui/getting-started/client-blazor
- server Blazor apps: https://docs.telerik.com/blazor-ui/getting-started/server-blazor

I know this is an old post, but the solutions offered didn't work for me either and they seem to be incorrect.
Removing the NuGet.Config after following Steps 1 to 4 makes no sense as those steps actually create the NuGet.Config file ... just chasing your tail if I follow those directions. Tell me to create the file, then next steps to delete file??
The issue is that I never get prompted to enter my Telerik Account credentials.
I don't understand the point of the Telerik Control Panel and selecting products to install if it doesn't actually install what is need to run a project using Telerik UI Blazor?
Rob.
Hi Rob,
That is a valid question and is sometimes a point of confusion. Let me explain the difference between the nuget packages vs local installation of the entire product, this will help you understand the decision you will want to make in the future.
It's good to step back and understand the difference between stuff that needs to be installed locally, and stuff that comes solely from NuGet.
Telerik UI for Blazor provides NuGet packages, which means you do not need to install anything using the Progress Control Panel. You can just add the Telerik NuGet server to your nuget.config and that's all that is needed for a project to add the references.
So, then what is the point of using the Progress Control Panel, and select "UI for Blazor" in there? That's how you get the Visual Studio Extensions, local demos, offline package sources/assemblies, and more. These will get installed to C:\Program Files (x86)\Progress\Telerik UI for Blazor [version]\.
Therefore at the end of the day, you're kind of doing two things (local product install and project-independent package add), but only the latter is necessary.
I hope this helps explain things, let me know if you have any further questions.
Side Note
Just as an experiment, try using the Telerik UI for Blazor project wizard for a quick throwaway project. You'll see int he wizard, we let you choose the package source for where the nuget.confgi will add a source.
You might be asking yourself "why would I use the Telerik server if I can add a local folder path to my nuget.config as a package source?". This depends on where that project is going to live.
- If it's only going to ever be on your PC, and you are never going to change the local installed version, then it's fine.
- However, if you plan on building this project in CI-Cd (Azure DevOps, GitHub Actions, etc), then you'll prefer using the nuget server as a package source because that project can restore packages from everywhere it can be compiled.
You can see this article for information on authentication the connection from CI Restoring NuGet Packages in CI - Telerik UI for Blazor.

that worked, great, thanks.
Next issue: After building the skeleton template installed through extensions -> Telerik -> Telerik UI for Blazor -> Create new project
running the resulting build yields a web page that simply says "Loading..." and nothing else...
Any idea?
Can you confirm the startup project is the .Server project in the WASM solution?
I'm also attaching a solution I created with the VS extensions and it works fine for me, so you can compare against it (e.g., with a tool like WinMerge to see what is the differences between the project you have that fails, and this one).
The loading sign not disappearing in a WASM app indicates that something fails during loading of the assets and/or a JS error is thrown, but what is the exact error and its cause is hard to tell based on the available information.
If comparing against the sample here does not help, please open a support ticket and send me the sample project that fails so I can have a look at it.

Hello,
It does not look like there are any errors here, but you can still check the browser console for runtime errors that can break the app, and for broken network requests (things like proxies, firewalls, antivirus programs can tamper with the browser requests and break them even if the server returns them properly).
Without being able to see, read and debug the code, I can only guess and I would encourage you to open a ticket if this issue persists so I can take a look and avoid further guesswork.

Do you get any errors in the browser console? Perhaps one of these: https://docs.telerik.com/blazor-ui/troubleshooting/js-errors?
Does a WASM project work on your end without the Telerik components?

I am sorry that you are having a hard time with our packages, James.
What we provide is the following:
- a private feed that you can add globally for your machine (see also the troubleshooting information in the article): https://docs.telerik.com/blazor-ui/installation/nuget
- .nupkg files that you can use as local custom package sources: https://docs.telerik.com/blazor-ui/installation/zip
The second approach should be quite easy as it merely requires copying files to a shared folder and pointing your nuget.config file that way. The first approach with our private feed is a tad mode complicated than with "regular" packages because:
- most free products are on nuget.org which is a package source that Visual Studio sets up for you - you don't have to do it yoursefl, like any other custom package source
- our components and software are not free, so they cannot be available from a free package source like nuget.org - this requires that we provide a private one, and that, inevitably, requires a bit of setup

Hi Frank,
We do have easy to follow instructions on how to add the Telerik Server to you package sources here => Telerik NuGet Feed - Telerik UI for Blazor
That being said, our installer does add a local package source for you, however, since you're having trouble with it, I imagine that's why you're missing the local source. So, I would recommend following the instructions in that link to add the Telerik NuGet server so you can get up and running quickly.
Ticket Escalation
I would like to also share that I've spoken with Seth, and I have escalated your situation to both the UI for Blazor and the Visual Studio Extensions support teams. You will have already gotten an email notification saying that a Support Ticket was opened for you (that was me, it is ticket #1635933).
Those teams are treating the case with priority, so you will get a quicker response than typical trial support response times.
Additional Assistance
If you have any questions in the meantime, please feel free to open the Support Ticket and post additional context about the current issue. Alternatively, you can open a new Support Ticket to get fast parallel assistance in different topics.
- You can see your current Technical Support tickets here => https://www.telerik.com/account/support-center
- You can open a new Technical Support ticket here => https://www.telerik.com/account/support-center/contact-us
I will be keeping a close eye on things to make sure there is smooth transition/communication across any relevant teams needed to assist you.
