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)

I am working on an ASP.NET Web API 2 project with .NET target framework 4.6.1. I am trying to setup github workflow for my repo. When the dotnet restore command is run, it throws an error like below.
I am getting the same error if I run the same command in from command prompt inside my project. Also if I run dotnet build, it shows below error.
The project builds fine from Visual Studio but not working from command line or github workflow yml. Can anyone please point me on what am I missing?
The project builds fine from Visual Studio but not working from command line
Check which sln file Visual Studio is using to build your project.
Since I don't see any sln/csproj in your GitHub repository, it is also possible that you have a .gitignore which would prevent adding those in the first place.
DOTNET Restore does not support pacakges.config https://learn.microsoft.com/en-us/dotnet/core/tools/dotnet-restore
So you have to move the nuget package references to csproj file itself
Here is a great comment on how to do that https://stackoverflow.com/a/65701746/8318698
Note: check that if multiple projectGuid is there on csproj at the end of the steps
After that you will be able to use dotnet restore without a hitch.
Error:
C:\WebApp\WebApp.csproj : error : The SDK 'Microsoft.NET.Sdk.Web' specified could not be found. C:\WebApp\WebApp.csproj
I am trying to open Dotnet core project and I am getting the above error.
I have installed the latest SDK from https://www.microsoft.com/net/core#windowscmd
I have checked the path for dotnet cmd and it works fine.
Am I missing something? Let me know if you need more information.
The target framework is set to .NET 4.5.2
I stumbled upon this issue a number of times recently. Here's a brief list of the workaround I found (one of them always worked until now):
Install the right .NET Core SDK: Either the latest version or the version required by your project.
Clean-up obsolete .NET Core versions: Go to Control Panel and uninstall previous .NET Core SDK/Runtime versions (as long as you don't use them anymore).
Create a Global.json file: Add a new global.json file to your project's root with the following content (replace the .NET Core version build with the one you want to run the project with):
{
"sdk": {
"version": "2.0.5"
}
}
Rename the SDK reference: Open your .proj file and replace <project sdk="Microsoft.NET.Sdk.web"> with <project sdk="Microsoft.NET.Sdk"> .
Add the MSBuildSDKsPath Environment Variable: The dotnet CLI sets the MSBuildSDKsPath environment variable when invoking MSBuild: however, a December 2016 patch changed the CLI behaviour so that it will respect an existing environment variable, if it has already been set: this will allow the developer to “force” the CLI to use a specific SDK.
Check your PATH: Verify that both C:\Program Files\dotnet and C:\Program Files (x86)\dotnet are in the PATH environment variable.
For additional info regarding the issue and other viable fixes check out this blog post that I wrote on this topic.
I agree with the comment on Sundeep's answer, you shouldn't have a global.json file in your project anymore.
It seems as though installing the .NET Core 2.0 SDK is causing issues with the PATH. Verify that C:\Program Files\dotnet and C:\Program Files (x86)\dotnet are in the PATH environment variable. In my case, these values were already present under System Variables so I added them to User Variables and rebooted my machine. This resolved my issue.
As suggested in the comment, I updated global.json file as shown below
{
"sdk": {
"version": "1.0.0"
}
}
Also, I had to remove the <ItemGroup> which contains wwwroot files path in .csproj file.
Reload the project and it works like a charm!
I've encountered the same problem, I just rename <project sdk="Microsoft.NET.Sdk.web"> to <project sdk="Microsoft.NET.Sdk"> on csproj
another situation:
https://stackoverflow.com/a/55529011/2971851
issue details: 2.1.6xx & 2.2.2xx version of the SDKs are only supported
on Visual Studio 2019. VS 2017 needs 2.1.5xx & 2.2.1xx versions of the
SDK.
How to fix the issue? Install 2.1.5xx version of the SDK if you are
targetting a 2.1 app Install 2.2.1xx version of the SDK if you are
targetting a 2.2 app.
and according to the official document:
Note: If you are a Visual Studio user, there are MSBuild version
requirements so use only the .NET Core SDK supported for each Visual
Studio version. If you use other development environments, we
recommend using the latest SDK release.
Do not uninstall previous SDK versions!
When I followed the 2nd step suggested in Darkseal's answer, uninstalling the previous SDK versions, it caused an "expected imports are missing" fatal error every time I opened up my project, so I needed to repair my Visual Studio, since installing the old SDK versions again kept popping up this error...
Also the other steps mentioned in that answer did not make any difference (both dotnet references were present in the environment variables and MSBuildSDKsPath was not needed for me).
Install the proper SDK version and select it in the Solution's Properties
As Jyoten mentioned I was using VS2017 x86 version and my SDKs were x64.
However, this was not the only issue, it seems there's some incompatibility with some SDK versions and VS2017. Having installed SDK v2.2.203 and v2.2.202, they would never showed up in the Target framework dropdown when I double-clicked the Properties on my project's solution (in the Solution Explorer (Ctrl+Alt+L)).
So I needed to install v2.2.105 x86 as mentioned in this answer, for it to show up in that dropdown.
Once it did, the solution that was requiring .NET Core v2.2 worked properly (did the Build normally).
I had this issue when I had to open a .Net Core 1.0.4 project in VS2017.
When I installed 1.0.4 SDK, i chose the x64 version which placed the sdk files in 'c:\Program Files\dotnet' ...
but my VS2017 was 32bit and was therefore looking for the sdk in 'c:\Program Files (x86)\dotnet'.
Once I installed the 32 bit version of the SDK it worked fine.
I was running into an issue where creating a new ASP.NET Core 2.0 project was giving me an error The SDK 'Microsoft.Net.Sdk.Web' specified could not be found, and leaving me unable to open the project in Visual Studio. The problem was the project was created in a folder that contained a global.json file, tying the SDK version to 1.0.0.
Deleting the global.json, or updating it to 2.0.0, fixed the issue. Be sure to check parent folders too - if any parent folder contains a global.json, the SDK version specified in the "closest" folder will be used.
I was getting this error in Visual Studio Code.
I was able to find the issue by setting the OmniSharp log settings in VS Code to debug. Once I did that I could see that it wasn't finding Microsoft.Build.Resources.dll.
I installed MS Build by repairing my VS 2017 Community installation. That fixed it.
uninstall and reinstall microsoft .NET core SDK.
then restart visual studio.
this works for me.
Choose the proper SDK according to your Visual Studio and Operating System. I downloaded the correct version from here https://dotnet.microsoft.com/download/visual-studio-sdks and after that .Net Core appeared in target frameworks list (there is a strict dependence between sdk version and VS version, so be careful).
I have solved this issue by,
go to this site, https://dotnet.microsoft.com/download
In that, install both .NET Core Runtime and .NET Core SDK.
After you install that, Open the Visual Studio 2017 with an administrator, Now The problem has been gone😊
I edited the .csproj file and changed netcoreapp2.2 to netcoreapp2.1 in this stanza & then I was able to get it working.
<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<OutputType>Exe</OutputType>
<TargetFramework>netcoreapp2.1</TargetFramework>
</PropertyGroup>
Install the proper SDK version and go to below links
https://dotnet.microsoft.com/download/dotnet-core/thank-you/sdk-3.1.403-windows-x64-installer
https://dotnet.microsoft.com/download/dotnet-core/thank-you/runtime-desktop-3.1.9-windows-x64-installer
This worked for me:
Make sure that the .NET folder where SDKs are and Visual Studio are
in the same program files (x86) or program files.
Provide the path to the SDK in the environment variable.
If anyone else stumbles upon this issue (including future me), I had the same problem and tried literary every solution proposed here and nothing worked. Finally what fixed the issue for me was deleting NuGetFallbackFolder in C:\Program Files\dotnet\sdk.
After deleting that folder, everything just started to work magically.
I had this error when from old project (in .NET 4.7.2) I was trying to do:
var project = new Microsoft.Build.Evaluation.Project(someDotNet6ProjectPath);
The solution was to upgrade Microsoft.Build packages.
I am trying to learn how to develop apps for UWP for both Desktop and Mobile. I have been currently working on getting the Entity Framework working in my app to store application state and followed the following link:
https://learn.microsoft.com/en-us/ef/core/get-started/uwp/getting-started
It worked well for Desktop, the issue however is that when I try to run it on the Windows Mobile emulator I get the following error in debug mode when the code reaches the db.Database.Migrate() step:
Unable to load DLL 'sqlite3': The specified module could not be found
In the link I pasted above, someone else had the same issue and in the comments they recommended to try the following:
Step 1: Install SQLite VSIX pacakge for Universal Windows Platform development using Visual Studio 2015
https://www.sqlite.org/2016/sqlite-uwp-3130000.vsix
Step 2: Install NuGet package SQLite.NET-PCL
Install-Package SQLite.NET-PCL
Step 3: Add references
Add Reference -> Universal Windows ->Extensions -> Make sure the following packages have been checked: "SQLite for Universal Windows Platform" "Visual C++ 2015 Runtime for Universal Windows Platform Apps"
After that, if you get the error "Payload contains two or more files with the same destination path 'sqlite3.dll', do the following:
copy sqlite3.dll from
C:\Program Files (x86)\Microsoft SDKs\UAP\v0.8.0.0\ExtensionSDKs\SQLite.UAP.2015\3.8.11.1\Redist\Debug\ARM\sqlite3.dll
past to (override it)
C:\Users\%USERNAME%\.nuget\packages\SQLitePCL.raw_basic\0.7.1\build\native\sqlite3_dynamic\winrt81\arm\sqlite3.dll
The problem after doing those steps is that I am now seeing the issue when doing a build for "Payload contains two or more files" however not in the SQLitePCL.raw_basic directory (I don't even seem that have that). Instead my error is the following:
Payload contains two or more files with the same destination path 'sqlite3.dll'. Source files:
C:\Users\admin\.nuget\packages\SQLite\3.13.0\runtimes\win7-x86\native\sqlite3.dll
C:\Program Files (x86)\Microsoft SDKs\UAP\v0.8.0.0\ExtensionSDKs\SQLite.UWP.2015\3.13.0\Redist\Debug\x86\sqlite3.dll
I have been searching everywhere and am truly stumped as to how to get my UWP program working on Mobile. Thanks a lot for your help!
It seems like you got the solution for resolving the exception The specified module could not be found from #Leandro_Medeiros_Machado 's comment on this document. If you got the Payload contains two or more files with the same destination path 'sqlite3.dll' exception after you done the above three steps you may be also found the next solution from the comment.
After that, if you get the error "Payload contains two or more files with the same destination path 'sqlite3.dll', do the following:copy sqlite3.dll from
C:\Program Files (x86)\Microsoft SDKs\UAP\v0.8.0.0\ExtensionSDKs\SQLite.UAP.2015\3.8.11.1\Redist\Debug\ARM\sqlite3.dll
past to (override it)
C:\Users\%USERNAME%\.nuget\packages\SQLitePCL.raw_basic\0.7.1\build\native\sqlite3_dynamic\winrt81\arm\sqlite3.dll
For you, you may need to copy from
C:\Program Files (x86)\Microsoft SDKs\UAP\v0.8.0.0\ExtensionSDKs\SQLite.UWP.2015\3.13.0\Redist\Debug\x86\sqlite3.dll to(override) C:\Users\admin\.nuget\packages\SQLite\3.13.0\runtimes\win7-x86\native\sqlite3.dll.
But actually, for using EF core you don't need the above steps and I recommend you check your environment instead of using the above workaround. I created a simple EF project by following the document and without install the VSIX I can run successfully on the emulator (build 10586). My VS build is 2015 update 3, my OS version is build 14393 and the EF core version is Microsoft.EntityFrameworkCore.Sqlite 1.1.0. So please firstly check if your environment met the following requirements:
Windows 10
Visual Studio 2015 Update 3
The latest version of Windows 10 Developer Tools
And if your EF core and EF core tools versions are right.
