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:

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?

Why is it such a mission to add Telerik newget packages ?? I dont have to go through hoops for any other third party providers to install or update nuget packages this is very frustrating and a waste of my time

I could not agree more.  Why do you waste people's time when they're already focused on their project (not learning your specific way to do things!).  if the same is true for your controls, then this trial will end very rapidly!

I am sorry that you are having a hard time with our packages, James.

What we provide is the following:

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

Then you should do all of that for us in your install program!  Or, at least provide EASY instructuions..  Not make us go to google to find out why there are errors.  or, better still, INSTALL THE PACKAGES FROM YOUR INSTALLER!

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.

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.
