Arithmetic operation resulted in an overflow


  • Previously used ASP.Net with VS2013 with SQL database connection to REMOTE database - and thought that I'd mastered how to create SQL-based web apps...until I tried the new ASP.Net Core with VS2015. Tried installing VS2015 Pro and followed PluralSight training for creating simple Visual C# project "ASP.NET Core Web Application (.NET Core)" - failed! Tried simple code example from other wbesites - also failed. Tried Microsoft's own example here: - also failed. The failures seem to occur when creating the initial database.

    Failed error: "Arithmetic operation resulted in an overflow"

    I am using Windows 10 Enrterprise (64 bit) clean install. Other software includes Office 2016 (32 bit) | Visio 2016 (32 bit).
    I have tried uninstalling any reference to "SQL" from the add/remove programs, and re-installed VS2015. Same problem.

    Can anyone shed light on this problem? It's inhibiting me from learning how to develop the most basic of we apps!

    Every "EF" project sample I try gives the same error: "Arithmetic operation resulted in an overflow". In the case of the above Micrsoft sample, I got as far as section "Create a controller and views", but when I click "Add" (to add a new scaffolded item) I get the following exception (image attached): [trace posted below]

  • Hi Virgil Turner,

    According to your description, you could not create new ASP.NET Core Web Application (.NET Core) project in VS2015. Please refer to the following steps to troubleshoot this issue:

    1). Please update the ASP.NET Tools for web in VS, click the Tools menu->Extensions and Updates-> Updates->click Visual Studio Gallery-> update the Microsoft ASP.NET and Web Tool option.

    2). Based on step1, update you VS to the latest version (VS2105 Update3 version 14.0.25431.01), update the option beginning with KB letters in Update list box.

  • Hi Virgil Turner,

    Since this issue occurs when creating the initial database and according to the error message, the issue occurs on create DBContext, I suggest you check whether you have installed SQL Server Data Tools for your Visual Studio first. You could check it from Control Panel -> Programs and Features -> Visual Studio 2015 -> Change -> Modify.

    If the SSDT has installed but there still has issues on creating the initial database, I suggest you repair your Visual Studio to check whether there has any installation issues.

    If any progression for this issue, please feel free to come back.

    Best Regards,
