What is the trial period for dotConnect for MailChimp?
dotConnect for MailChimp offers a fully functional 30-day trial. During this period, you can use and evaluate all features without limitations. After the trial ends, you can purchase a license to keep using the product.
Why do I need to install the product if NuGet is available?

  • For .NET (.NET Core/.NET 5+) projects: Use the assemblies available via NuGet packages.
  • For .NET Framework projects: Use the Devart assemblies included with the product installer.
Where should I apply my License Key?

  • For .NET (.NET Core/.NET 5+) projects, apply the License Key at runtime using the License Key connection string parameter.
  • For .NET Framework projects: no license key is needed. Simply download and install the licensed version of dotConnect from your Devart Customer Portal.
Do the end users of my application require a Devart license, or must I pay additional fees for deploying my software?

No, end users do not need a Devart license, and there are no additional deployment fees, as long as you hold a valid Devart license.

According to the EULA, you're allowed to redistribute the following runtime assemblies with your application:

  • Devart.Data.MailChimp.dll
  • Devart.Data.dll

You can include them in your app's folder (such as Bin for web apps) or register them in the GAC. Just make sure they are only used by your solution.

There's no need for a full installation on the target machine, you can also use the "Minimal installation" option provided by the setup.

No other components of dotConnect may be distributed.

How can I update dotConnect to a new version?

To update dotConnect to a new version, you need to reinstall it:

  • Open Settings > Apps > Installed apps in Windows
  • Uninstall the current and any older versions of dotConnect, including Entity Developer and LinqConnect, if installed.
  • Visit the Customer Portal and download the latest licensed version.
  • Install the downloaded version and receive the latest features and improvements.
How can I completely remove all the previous versions of the product?

1. Go to Settings > Apps > Installed apps and uninstall:

  • All dotConnect providers
  • Entity Developer
  • LinqConnect

2. Manually delete any leftover files from the following locations (if they exist):

GAC folders:

  • C:\Windows\assembly\GAC_MSIL
  • C:\Windows\Microsoft.NET\assembly\GAC_MSIL

Program files and extensions:

  • C:\Program Files (x86)\Microsoft Visual Studio\...\Community\Common7\IDE\Extensions\Devart

  • C:\Program Files\Common Files\Devart

Program data folders:

  • C:\ProgramData\Devart\dotConnect
