Omnisharp does not seem to recognize my installed .NET sdk (version 6.0.408).
I have tried manually adding this path via settings to Omnisharp: SDK path i.e.:
C:\Program Files\dotnet\sdk\6.0.403
I have also tried reinstalling the SDK and even VSCode.
This does not seem to solve the issue however, and I am unable to run my asp.net application on VSCode. Running dotnet run from the terminal is fine.
TLDR: Both .NET SDK versions and Visual Studion versions needed to be x64.
Here was the exact error I was seeing in the Output Window:
[ERROR] A .NET 6 SDK for x86_64 was not found. Please install the
latest x86_64 SDK from
https://dotnet.microsoft.com/en-us/download/dotnet/6.0.
[ERROR] Error: OmniSharp server load timed out. Use the
'omnisharp.projectLoadTimeout' setting to override the default delay
(one minute).
When I realized there was a mismatch between my .NET SDKs and Visual Studio Code in terms of being x86 and x64, I did the following:
Deleted the bin/obj folders and .vscode folders in my VS Code project.
Uninstalled my .NET SDKs via Windows (Setings > Apps).
Uninstalled Visual Studio Code via Windows (Setings > Apps).
Installed .NET 7.0 x64 and .NET 6.0 x64.
Opened PowerShell and ran dotnet --info to make sure my .NET runtime and SDK were appearing correctly.
Installed Visual Studio Code x64.
Used PowerShell and cd'd to my project folder. Did a dotnet restore. Then launched Visual Studio Code using code . command.
I could then use the most current version of the VS Code extension (v1.25.2).
Uninstalling and then installing the VSCode extension C# for Visual Studio Code solved the issue for me.
I had the same problem and just solved it. Copy and pasting this from a Youtube comment I just finished writing, so it might sound funny out of context, but the good bits are in there. Hope it helps.
Installed dotnet 7.0, but then it said dotnet 6 was missing...
So I deleted the script asset, exited Unity, went back to their website and installed Net 6.0.403
Error still happened.
I'll note this seemed to push a script compiling error out to Unity in the inspector window, as well.
Deleted the script asset again, exited Unity again, then uninstalled both dotnet 7 and dotnet 6.
Then I reinstalled dotnet 6.
Into unity, made a new script, opened it, and this time no error message about missing net 6.
I just started yesterday. Literally. So if my solution is trash, I'll laugh with you lol. Best of luck.
I upgraded Visual Studio Community to the final release, and it stopped working. Specifically, I could generate a new project, but when I try to load it, it gave me an error
Critical Project 'SdkTest' load failed| [MSB4236] The SDK 'Microsoft.NET.Sdk.Web' specified could not be found. ...\SdkTest.csproj
Even though build and run worked fine
I ran "repair" on VS2022, and it seems to be working now from Visual Studio. However, dotnet --info doesn't show any SDKs; only runtime; and dotnet build or dotnet new give an error:
C:\Code>dotnet new console -o myapp
Could not execute because the application was not found or a compatible .NET SDK is not installed.
Possible reasons for this include:
* You intended to execute a .NET program:
The application 'new' does not exist.
* You intended to execute a .NET SDK command:
It was not possible to find any installed .NET SDKs.
Install a .NET SDK from:
https://aka.ms/dotnet-download
I even reinstalled .NET 6 and I see it in the list of applications (along with older SDKs). I checked the path, and I see everything that I expect to see:
C:\Program Files (x86)\dotnet\
C:\Program Files\dotnet\
C:\Users\me\.dotnet\tools
I am running Windows 11.
It's known bug in VS2022 installation.
Problem is that dotnet you access is located inside Program Files(x86)/dotnet, but all sdk's are located in Program Files/dotnet. You simply need to edit PATH environment variable so Program Files/dotnet goes before Program Files(x86)/dotnet. If you don't see Program Files(x86)/dotnet in user environment variable (which is likely to happen) then edit system environment variable (located below)

When I am trying to install CMake I get the error:
Visual Studio 15 2017 could not find any instance of Visual Studio.
I am using Windows 7 and Visual Studio 2017. The CMakeOutput.log file writes:
The system is: Windows - 6.1.7601 - AMD64
Any ideas?
I ran into the same error and performed the following steps to resolve the issue:
Open Visual Studio
Go to Tools -> Get Tools and Features
In the "Workloads" tab enable "Desktop development with C++"
Click Modify at the bottom right
These steps resulted in the "Visual C++ tools for CMake" feature being installed, but the other optional C++ features included in this workload may also helpful for what you are trying to do.
After the Visual Studio updater finishes installing try re-running the command. You may need to open a new command window.
In my case, I installed Visual Studio, selecting the workloads and modules that I wanted, but I ignored the request to reboot, assuming that shutting down the computer at the end of the day and restarting it the following day would suffice. I was wrong.
The following day I tried a cmake build and got the "could not find any instance of Visual Studio" error. After several attempts to resolve, I re-ran the installer, made no changes to the configuration, and clicked Modify. This time I let it reboot the computer. The reboot took a long time. After which my cmake build worked.
If you have already installed the workload Desktop development with C++ and still getting the following errors while using visual studio 2022 for flutter
Generator
Visual Studio 16 2019
could not find any instance of Visual Studio.
Building Windows application...
Exception: Unable to generate build files"
Solution: Follow these steps,
Edit your_flutter_path\packages\flutter_tools\lib\src\windows\build_windows.dart, and change the constant on line 28 from Visual Studio 16 2019 to Visual Studio 17 2022
Delete flutter_tools.stamp and flutter_tools.snapshot from your_flutter_path\bin\cache\
Run flutter clean in the project
I had the same issue "could not find any instance of Visual Studio"
but with Visual Studio 2019 (Community Edition) and I just had to configure the VS160COMNTOOLS variable so that CMake correctly detects Visual Studio.
export VS160COMNTOOLS="/c/Program Files (x86)/Microsoft Visual Studio/2019/Community/Common7/Tools"
(cf https://cmake.org/cmake/help/latest/generator/Visual%20Studio%2016%202019.html)
With Visual Studio 15 2017, the variable you need should be VS150COMNTOOLS.
(cf https://cmake.org/cmake/help/latest/generator/Visual%20Studio%2015%202017.html)
NB: in my case, in a Travis-CI workflow, I installed Visual Studio using the commands (no need to reboot):
choco install visualstudio2019community
choco install visualstudio2019-workload-nativedesktop # required
With only the first package, CMake detection of VS2019 failed.
I was configuring a Jenkins build node and could successfully run CMake GUI manually but command line use or builds using the CMake plugin would fail with:
Visual Studio 16 2019 could not find instance of Visual Studio.
-A x64 parameter was added with no change in result.
The problem was that CMake could not determine the Windows SDK version.
By adding CMAKE_SYSTEM_VERSION parameter CMake was then able to find Visual Studio.
-D CMAKE_SYSTEM_VERSION=10.0.18362.0 (use your windows SDK version)
Environment:
windows 10 system build: 19042
CMAKE 3.19.4
VS 2019 Professional 16.8.4
Jenkins 2.235.1
Full command line that worked:
"C:\Program Files\CMake\bin\cmake" -G "Visual Studio 16 2019" -D CMAKE_BUILD_TYPE=Release -A x64 -D CMAKE_SYSTEM_VERSION=10.0.18362.0
When using VS 2017, be aware that this is really VS 2015, and CMake identified it as VS 2017 2022 which is not the version of VS 2017 I had, that gave me this error. So the conclusion I offer is to try different versions, specifically the 2015 one.
I had a similar issue where installing libzmq in my npm project was throwing the same error and that wasn't getting solved by enabling "msbuild" under "Desktop development with C++" in the Visual Studio installer.
My solution ended up being to reinstall the Windows build tools for npm with the following command.
npm install --global windows-build-tools
Note: Remember to run the command prompt (or whatever terminal you are using) as admin before running this.
If the CMake used to work with the installed Visual Studio and is broken someday, then the problem could be VS requires system reboot to complete some update.
For quick verification, rename HKLM\SOFTWARE\WOW6432Node\Microsoft\VisualStudio\Setup\Reboot to like HKLM\SOFTWARE\WOW6432Node\Microsoft\VisualStudio\Setup\Reboot.bak, then re-run cmake which should succeed. Don't forget to rename the registry back and reboot the system if this is the problem.
In my case, I was selecting different version of visual studio in that configuration dialog box whereas I installed different version.
Do select the same version.
Above solutions did not solve this issue for me. After installing node.js from https://nodejs.org/en/download/ apparently a correct version of windows-build-tools was installed
I reinstalled the Visual Studio 2019(my former one is 2017 version ) with all those settings required(my cmake version is 3.23.0),and it works. So try to install different versions.
In my case, the problem was gone after I deleted the previous cmake result directory and then ran cmake again.
if you have installed two or more Windows 10 SDK, delete them excluding latest one.
Try downloading the windows-build-tools package.
npm install --global --production windows-build-tools --vs2015
This step should be the end-all-be-all solution to fixing node-gyp problems. For most people, that’s true. NPM has a package called windows-build-tools that should automatically install everything you need to get node-gyp working, including the Microsoft build tools, compilers, Python, and everything else required to build native Node modules on Windows.
Recently, I created an asp.net core project using Visual Studio Code on Windows and pushed it to GitHub. When I cloned the repo from GitHub and attempted to do a dotnet restore on the project on Ubuntu, an error message stating there was no project.json file was returned. Can anyone point me to a resource that will show me how to properly restore a .net core project from a Linux machine? Thanks!
So it seems like on each of your machines you are running different versions of the .net core SDK.
A big caveat with what you are trying to do. Are you trying to use Project Rider from Jetbrains on Linux? This only works with project.json (As of the time of this post) so be wary of that.
Now there are two ways to do this. If you are wanting the very latest on Linux and don't care about using Rider, then you can go here : https://github.com/dotnet/core/blob/master/release-notes/download-archive.md and download the latest release for both Linux and Windows, install on both and you should be good to go.
If you do care about using Rider or you aren't ready to be strapped in for the wild ride of the latest release. Then you can do the following.
Find what version of the SDK you have on linux by typing into a terminal the following :
dotnet --version
This will spit out what version you have on linux. Go here and download the same version for windows and install it on your windows machine (https://github.com/dotnet/core/blob/master/release-notes/download-archive.md).
Now BEFORE you create a project, create a solution folder and create a file in it called global.json. Inside that put the following :
"sdk": {
"version": "1.0.0-preview2-003131"
}
Where the SDK version matches what you got from your linux terminal. Now create a folder for your project inside the solution folder. Run "dotnet new -t web" or a similar command to create your project. It will inspect the SDK version of the global.json and create a project with the tooling that matches. You should then be able to shift this project around any machine that has the same SDK installed, even if it also has the latest SDK's also.
If you do not create the global.json, it defaults to the latest version (Atleast on Windows).

I'm working with Visual Studio 2015 RC and following a tutorial for adding Facebook auth. It says to store the Facebook App Id as a secret using the SecretManager app:
"Set the Facebook AppId by running user-secret set Authentication:Facebook:AppId 862373430475128"
I am not quite grasping how to install the SecretManager, or how to access it from a command line. I'm used to VS2010 and so the dnvm/dnu stuff is totally new to me. Here's what I've tried:
opened a regular command prompt and typed dnvm - that works; it's in the PATH
typed user-secret - not recognized
tried to install SecretManager via dnvm - got an error partway through
added SecretManager to my project via nuGet - worked but I don't get where to go to type "user-secret"
Can someone provide a simple set of steps to get to where I can use the "user-secret" command?
UPDATE: After manually adding the dnu tool to my Path and running
dnu commands install SecretManager
I got the following command line output:
GET https://www.nuget.org/api/v2/FindPackagesById()?Id='SecretManager'.

I know how to install nuGet packages for a specific app, but I'm less clear on how the global tools concept works. I'm currently on VS 2010, so this is mostly new to me.
See https://github.com/aspnet/Home/issues/601 . A user there had the same issue with SecretManager and his solution (editing the dependency version at C:\Users\myname.dnx\bin\packages\SecretManager\1.0.0-beta4\app) worked for me.
I'm still not 100% clear on why I had to manually set up the PATH to the dnu tool, but I'm guessing that the community edition is just missing the VS command prompt and other items.
