Unable to build the ASP Net Core 7 in azure devops pipeline CI

Question

ASP.Net Core 7 cannot be built in the Azure Devops Pipeline (CI) using the Classic pipeline and the ASP.Net Core template.

Error message : 

##[error] C:\Program Files\dotnet\sdk\6.0.203\Sdks\ Microsoft.NET.Sdk\targets\

Microsoft.NET.TargetFrameworkInference.targets(144,5): 

Error NETSDK1045: 

The current.NET SDK does not support.NET 7.0 targeting. 

Either target.NET 6.0 or lower, or use a.NET SDK version that supports.NET 7.0.

Answer 1

Create a task to instal the required.NET version. (You can modify 7.x to be more specific)

  - task: UseDotNet@2
    displayName: 'Use .NET Core SDK 7.x'
    inputs:
      packageType: sdk
      version: '7.x'
      installationPath: $(Agent.ToolsDirectory)/dotnet

Answer 2

First in the repos check the .Csprojfile

<PropertyGroup>

    <TargetFramework>net7.0</TargetFramework>

as per the target framework we should build using Same .Net version only and we should build with .Net core 7.0.x and add nuget restore task and the pipeline will run without issue.
