Examples do not seem to build anymore about windows-universal-samples HOT 24 CLOSED

Have you been able to successfully build a blank Universal Windows application? Typically these errors are due the NuGet cache for .Net 5.0 not being downloaded.

from windows-universal-samples.

Yes i have i have a universal windows application running at the moment.

Running two Solutions side by side(one working and one Microsoft/Windows-universal-samples
Webview not working) I found some differences in references and tried to download the missing one with Nuget Package Manager and got the following result :

Maybe this is a clue to resolve this.

from windows-universal-samples.

Try deleting the hidden file Project.Lock.json that is in any of the folders, and retry.

Additionally, this is a large sample that pulls in many language technologies. Change your target to "x86" instead of "Any CPU".

from windows-universal-samples.

I could not find Project.Lock.json (made sure all files were visible).
Deleting Project.Lock.json in working project gave me the same kind of errors , so i decide to add a random Project.Lock.json file, rebuild the solution.
This reduced the amount of errors from 84 to 22.
I Think all the remaining and 4 warnings are because of the random Project.Lock.json file.
How can i get the Project.Lock.json file.belonging to webView sample?

from windows-universal-samples.

I've found that this error is common to all projects that were built with VS 2015 RTM and then moved to VS 2015 final. The files project.json and project.lock.json were not present/necessary up to RTM, but are now required apparently. If they are not there you get thousands of error because of the missing references listed in the json file. The easiest way out I've found is to create an new empty project and copy the two json files to your existing project. It might also be necessary to add a reference to the json file in the project csproj file. Just open the empty project csproj file to see where to add the reference. In my case all errors have disappeared after doing this (except a few problems with duplicate references due to older libraries still referenced)

from windows-universal-samples.

shinsenai is correct. The Project.lock.json file should be autogenerated by Visual Studio from the project.json file. Can you tell us what version of Visual Studio you are using? (The project.json requirement arrived very late.)

JS projects can be "Any CPU", however in general for UWP projects, CS cannot be anycpu. Change your build target to "x86". This is the cause for most of the errors.

It also looks like WebView has a bad reference to System.Numerics.Vectors and System.Numerics.Vectors.WindowsRuntime. in the StreamURIResolverCS.csproj. Delete these.
Then do "Build->Clean" and then "Build->Rebuild All"

We'll clean up the references in the next update.

from windows-universal-samples.

I have my target as x86 and noticed the bad references, but there is more:
After updating NuGet package manager and copying Project.Lock.json file from Blank App
and rebuild I have 0 errors but cannot debug or run the app.
Shared content is not copied into solution.
I will try to copy these into the solution and let U know if it succeeds.

from windows-universal-samples.

Did you unzip the entire repo or only extract specific samples? You should unzip the entire repo as the projects use Visual Studio Links to refer to the SharedContent folder.
Also the Project.Lock.json file should be regenerated. If it is not, then you should double check your nuget options:

•Verify both "package restore" options are checked
◦Right-click on project, choose "Manage NuGet packages
◦Open settings (click on the small "gear" icon in the top right
◦verify both "package restore" options are checked
•After adding the package source, exit VS, goto the project directory and delete the package.lock.json file. Reload the project, Clean then ReBuild

from windows-universal-samples.

Packet package restore options were not checked, fixt that,
updated Nuget Packet sources,
deleted all the webview projects I messed with.
Did a new unzip of the entire Repo.
Reloaded the project, ReBuild : 0 errors, 5 warnings:

see my earlier comment about removing the unnecessary System.Numerics references:

Sharedcontent is not copied locally, it is already linked in the project file. You should be able to F5 and debug or run. What error do you get when you F5 or when you do Build->Deploy?

from windows-universal-samples.

Just a messageBox poping up.
Message:The debugger cannot continue running the process. Unable to start debugging.
Nothing else.

from windows-universal-samples.

I get that too. Run the program without the debugger. Something about JS debugging is messed up.

from windows-universal-samples.

I have no option to run the program without the debugger?

Launch it from the Start menu.

from windows-universal-samples.

Very strange. I will contact some folks in Visual Studio to see what they think might be the problem.

In the mean time, can you try another simple sample. ContextMenu has C#, CPP, and JS versions. try all 3 and see if you can debug. Be sure to set your config to "Debug|x86" for

from windows-universal-samples.

(accidentally hit comment to early)
"Debug|x86" for C# and CPP.

from windows-universal-samples.

App is running from Start menu!!!!
Hope to be able to use debugging soon, so I can modify code for learning the right way for making universal Apps.
Thank You all for now.

from windows-universal-samples.

I hope something is being done on this one, specifically the reason the building RC samples stopped building in RTM.
In my case, I ended up adding the project.lock.json file from a blank file, and then after reading this text, deleting it, and NOT changing the NUget settings, but then restarting Visual Studio, and restarting, and suddenly, and inexplicably, the project.lock.json got created.
The creation or not of project.lock.json seems to be causing these problems. Have you guys discovered why sometimes that file doesn't get created, even in the case of having all the nugget settings correct?
-thanks

from windows-universal-samples.

You'll have to ask the Visual Studio team.
