    Hi @Santu Modak

    Welcome to Microsoft Q&A! 

    Please go to the project folder and check if you can find the NuGet package Microsoft.Net.Compilers in the packages.config file or packages folder.

    <package id="Microsoft.Net.Compilers" version="2.4.0" targetFramework="xxx" /> 

    If you can’t find the NuGet package, maybe it is not installed properly. You can remove all snippets about this package in the project file (updatecomp_project.csproj). Then, reload the project and rebuild the project. 

    If you can find it, please go to .csproj file and check that the path is correct like the following:

    <HintPath>..\packages\Microsoft.Net.Compilers.2.4.0\xxxx</HintPath> 

    Please correct the path and restore the package in Visual Studio.

    If it doesn’t work, you can try to remove the following snippet in the .csproj file:

    <Target Name="EnsureNuGetPackageBuildImports" BeforeTargets="PrepareForBuild">
    <PropertyGroup>
      <ErrorText>This project references NuGet package(s) that are missing on this computer. Use NuGet Package Restore to download them.  For more information, see http://go.microsoft.com/fwlink/?LinkID=322105. The missing file is {0}.</ErrorText>
    </PropertyGroup>
    <Error Condition="!Exists('..\packages\Microsoft.Net.Compilers.2.4.0\xxxx')" Text="$([System.String]::Format('$(ErrorText)', '..\packages\Microsoft.Net.Compilers.2.4.0\xxxx'))" />
    
    
    

    Then, reinstall the packages via Package Manager Console (Tools > NuGet Package Manager):

    Update-Package -reinstall 

    Sincerely,

    Anna
