[Rohit_More]

Getting the error post Legacy to Windows migration, how can we fix this?

Validation Error BC31424: Type ‘System.Net.Mail.MailMessage’ in assembly ‘3bcd00f4-a916-40f9-b663-68496de3fbfd, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null’ has been forwarded to assembly ‘System.Net.Mail, Version=6.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51’. Either a reference to ‘System.Net.Mail, Version=6.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51’ is missing from your project or the type ‘System.Net.Mail.MailMessage’ is missing from assembly ‘System.Net.Mail, Version=6.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51’

@camilo_gonzalez Then follow the steps Close the project and rename the project.json file and reopen and check if its resolved Go to .Nuget folder (Location:C:\Users\<Username>\.nuget\Packages) and rename the packages folder and then reopen the project and check if the issue persists If the issue is still there create a new project and check if the issue there in that project also, If yes then try downgrading the packages to older stable versions like 22.x cheers

@Rohit_More, Close the project Take backup of the project.json file. Delete the project.json file from project. Open the project by double clicking on the Main.xaml file Allow Studio to rebuild the project.json Check if it resolves your issue. Thanks, Ashok
