Why I could not build this "https://developer.microsoft.com/en-us/graph/quick-start" using VS 2022

Phong Nguyen 0

When play with this Microsoft Graph quick start project, I open it in my MS 2022, rebuild the solution, but get this error :"Error NETSDK1045 The current .NET SDK does not support targeting .NET 7.0. Either target .NET 6.0 or lower, or use a version of the .NET SDK that supports .NET 7.0. GraphTutorial C:\Program Files\dotnet\sdk\6.0.313\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.TargetFrameworkInference.targets". BUT But I build it in my cmd window, it works OK?

I download .Net 7.0.304 and see it in my C:\Program Files\dotnet\sdk\ and also see this sample using .Net 7 (in the Readme).

Hi @Phong Nguyen ,

Welcome to Microsoft Q&A!

Please have a try with the following workarounds:

Update your VS2022 to the latest version with Visual Studio Installer.
Change the target framework to .NET 7.0 and rebuild your project:

Right click on project > Properties > Application > General > Target framework > switch to NET 7.0.
Open your project file and check the target framework:

<TargetFramework>net7.0</TargetFramework>

If the .NET 7.0 is not appeared in Target framework, please close all running VS instances and go to Visual Studio installer > Modify > Individual components > ensure that .NET 7.0 Runtime is checked.

Check the installed versions of .NET (open a Developer Command Prompt for VS 2022 and run this command):

dotnet --list-sdks

You can refer to: NETSDK1045: The current .NET SDK does not support 'newer version' as a target.

Sincerely,

Anna

Thanks Anna. When I tried to get the property of the project, I got an exception, few lines of them are "Microsoft.VisualStudio.ProjectSystem.Query.QueryExecutionException: Object reference not set to an instance of an object. ---> System.NullReferenceException: Object reference not set to an instance of an object. at Microsoft.VisualStudio.LanguageServices.CSharp.ProjectSystemShim.EntryPointFinder.FindEntryPoints(INamespaceSymbol symbol) at Microsoft.VisualStudio.ProjectSystem.Properties.StartupObjectsEnumGenerator.<GetListedValuesAsync>d__8.MoveNext()"

But when I opened the GraphTutorial.csproj using Notepad++, I could see the target framework is correct.

<PropertyGroup>

<OutputType>Exe</OutputType> <TargetFramework>net7.0</TargetFramework> <ImplicitUsings>enable</ImplicitUsings> <Nullable>enable</Nullable> <UserSecretsId>2275df63-2eb2-47b9-a11f-710535686d4b</UserSecretsId>

</PropertyGroup>

When I list the sdk, I got all versions like these

C:\Program Files (x86)\Microsoft Visual Studio\2022\BuildTools>dotnet --list-sdks

6.0.313 [C:\Program Files\dotnet\sdk]

7.0.100-rc.1.22431.12 [C:\Program Files\dotnet\sdk]

7.0.304 [C:\Program Files\dotnet\sdk]

I also update my VS Professional 2022, and then try to do "Visual Studio installer > Modify > Individual components > ensure that .NET 7.0 Runtime is checked. ", BUT I don't .NET 7.0 Runtime in the list?

I also did review the article you mentioned above

Sorry for my delay reply!

Could you create a new project and check if it occurs in specific project?

You can manually install the .NET SDK 7.0.305 and try again.

Hi Anna,

I have all kind of problems and cannot figure out, do you mind loading this tutorial in VS 2022 to see if you see the issue I saw? Thanks.
