When I create a new Xamarin.Forms project I got the yellow triangle telling me that I am missing some packages.
Here is what I did:
I reinstalled Visual studio 2017 (I am using version 15.8.9).
If I re-open the project, it's just gone. There is no SDK under the Dependencies anymore.
I used Nuget Package Manage console to try to install the missing library, but nothing happened.
So I would like to hear you guy's opinions. Thank you.
So I figured out the solution. I updated my windows 10 to the newest version and the problem solved!
Came across this issue.
Created a new xamarin forms project using netstandard and got broken references.
Updating all packages in nuget solved the issue.
First build after updating package can take a little bit if xamarin decides that it needs to update its packages.
I feel guilty asking a question like this around here, but I'm at a loss and would appreciate some help.
A proof-of-concept like web application was built on one PC and put up on a repo to download on another PC at a different location. There was originally an auto-build feature set up where Azure would build and publish automatically on check-in, but that was removed. Things were working on both ends until one side included a bulk of excluded changes. Now I'm seeing the following error:
The "Microsoft.CodeAnalysis.BuildTasks.Csc" task could not be
loaded from the assembly
...\packages\Microsoft.Net.Compilers.1.0.0\build..\tools\Microsoft.Build.Tasks.CodeAnalysis.dll.
Could not load file or assembly
'file:///...\packages\Microsoft.Net.Compilers.1.0.0\tools\Microsoft.Build.Tasks.CodeAnalysis.dll'
or one of its dependencies. The system cannot find the file specified.
Confirm that the declaration is correct, that the assembly
and all its dependencies are available, and that the task contains a
public class that implements Microsoft.Build.Framework.ITask.
Does anyone have any suggestions on where to begin looking for the issue?
It turns out that NuGet packages were committed to the repository and breaking everything. Deleting the project\project\packages directory from the repo solved all build problems since NuGet fetches the packages automatically on build.
I got this error when I created a new branch for my project.
It drove me crazy for an hour. I tried most of the suggestions over the internet including the accepted answer to this question.
I then closed the project, opened it again, cleaned it and the error is gone. So this means this could be cache issue.
Anyways, just wanted to share.
I too tried the top answer with no luck so deleted the contents of my bin and packages dir, closed and re-opened VS and everything fine now.
I have tried all solutions described before, but none worked.
What solved it for me, was to update the Microsoft.Net.Compilers from the NuGet Package Manager
Right-click on your solution.
Go to Manage Nuget Packages.
Search for Microsoft.Net.Compilers.
Install or update on dependent projects as necessary.
Re-build, clean solution and restart Visual Studio worked for me.
Deleting the package and cleaning the solution solved it for me.
Deleting these three directories solves the problem.
/packages
/bin
/obj
NOTE: delete both /bin and /obj from all projects included in the solution (including Test projects).
Problem hides on TFS, you need to remove folder TestProject...\packages from TFS, check in, delete it from your local dir and build again. Worked!
Use the below step:
1) Delete the package folder.
2) close the visual studio.
3) open the project and rebuild the project.
I delete all from packages folder and rebuild solution. It's worked for me.
In my case: this works for me.
It turns out my teammate had already started looking into Windows 10 development and had Microsoft Build Tools 2015 installed on his machine.
I installed the software from https://www.microsoft.com/en-us/download/details.aspx?id=48159 and the problem was solved.
In my case, the solution was:
Use Windows Explorer and navigate to the offending path:
C:\MyApplication\Code\Main\ABCProject\ABCProject.UI\Bin
Right click on bin folder > select properties > Uncheck ReadOnly.
In my case, the solution was:
Right Click on Solution.
Go to Manage Nuget Packages for this Solution.
Search for Microsoft.CodeDom.Providers.DotNetCompilerPlatform.
Uninstall the searched Package.
Restart the Visual Studio.
I just tried this on a clean install of a Windows 10 machine and the issue for me ended up being that I didn't have the .NET 3.5 framework installed. This stackoverflow question helps explain why.
Cannot build WIX project on windows 10
Right Click on Solution.
Go to Manage Nuget Packages for this Solution.
Search forMicrosoft.Net.Compilers on Browse Section.
Deleting the bin folder worked for me
In vs2017 community there appeared a new item in the "build" menu. It disappeared after I used it and was called something like "Optimise project build packages". I clicked it and it fixed everything, just restart etc. I did it on two machines.
What it did was removed Microsoft.net.compilers 2.10.0 and replaced with Microsoft.CodeDom.Providers.DotNetCompilerPlatform 2.0.1
So there you go - more automagic...
My project was built with .Net Core 2.2 but I had .Net core 3.0 preview installed. I uninstalled .Net Core 3.0 from my system and went through all my class libraries, removing Microsoft.Net.Compilers 3.0, then rebuilt and it worked.
I moved my solution from one drive to another, and one of the files could not be copied because "in used", for which I click ignored, producing the error described in this post. Copying the missing file manually fixed it.
file: Microsoft.Build.Tasks.CodeAnalysis.dll
Destination directory: packages\Microsoft.Net.Compilers.2.1.0\tools
For me I was trying to open a MVC5 project in VS 2013 and I was getting this error, Opened it in VS 2017 and up it worked just fine.
I want to fix some issues with rvm and Aptana Studio 3. Is there a CONTRIBUTING.md somewhere I can use to bootstrap my environment to develop the plugin?
Aptana mantains their repos at github. Also, you can search in the tracker if there is any item related to your issue open, or open a new one yourself asking for help.
There's a bug for a feature I use in the recent update of Aptana Studio. The bug tracker implies the issue is fixed, but implies that it will be included in an update in late May. Does Aptana Studio have nightly builds that can be downloaded and if so from where?
I can't find anything in the forums or from google and the options on git hub look older and not official.
Yes. Go to http://preview.appcelerator.com where you can download nightly versions.
Here is a link that shows how to get latest updates from Aptana Studio.
What is the official release update URL for Aptana Studio 3.0?
(Another answer here gave a link to Appcelerator.)
Here is how to get the beta version:
http://preview.appcelerator.com/aptana/studio3/standalone/update/beta/
Release Candidate:
http://preview.appcelerator.com/aptana/studio3/standalone/update/rc/
This url can be used within Aptana to update to the nightly builds, but I have not tried it. It is for the plugin version of Aptana:
http://preview.appcelerator.com/aptana/studio3/plugin/update/nightly/site.xml
newbie here, sorry if this is an obvious question.
I have never used SQLite before. According to this page, the latest version of System.Data.SQLite should be downloaded from http://system.data.sqlite.org/.
But I couldn't find a download link. Should I download the source code then compile it on my local machine? If so, could you please tell me where to download the source code? Sorry, I have no idea what "Branches", "Leaves", "trunks" mean.
Thanks!
I just had this same issue. You can get the source code from here. It builds fine for me in VS2010.
Try this link instead: http://sqlite.phxsoftware.com/
The new http://system.data.sqlite.org/ site is the integrated web-server of a Fossil repository. Therefore it exposes SCM functionality like branches in its web-interface. You may take a look at fossil at: http://www.fossil-scm.org/
The latest System.data.sqlite binaries are available at
http://system.data.sqlite.org/index.html/doc/trunk/www/downloads.wiki
It has instructions/info and the latest binary versions for the variations of .Net and Visual Studio.
