Setup License from config file

The license name and key can be added directly in the app.config or web.config file in the appSettings section.

<appSettings>
	<add key="Z_Dapper_Plus_LicenseName" value="[licenseName]"/>
	<add key="Z_Dapper_Plus_LicenseKey" value="[licenseKey]"/>
</appSettings>

Setup License from appsettings.json file (.NET Core)

The license name and key can be added directly in the appsettings.json.

{
  "Z.Dapper.Plus": {
    "LicenseName": "[licenseName]",
    "LicenseKey": "[licenseKey]"
  }
}

Setup License from code

The license can be added directly in the code of your application. Make sure to follow recommendations about where to add this code. Upon purchase completion, an email will be sent with your license key information.

// using Z.Dapper.Plus; // Don't forget to include this.

string licenseName = //... PRO license name
string licenseKey = //... PRO license key

DapperPlusManager.AddLicense(licenseName, licenseKey);

ENSURE to always test the license the first time you set it up.

Recommendations

• Use the config file to store your license name and license key.
• Web App: Use Application_Start in global.asax to activate your license.
• WinForm App: Use the main thread method to activate your license.
• Win Service: Use the OnStart method to activate your license.

The AddLicense must be set before the first call to the library. Otherwise, the monthly trial will start.

How can I check if my license is valid?

The validate method allows you to know whether your license is valid or not.

// CHECK if the license is valid for the default provider (SQL Server)
string licenseErrorMessage;
if (!Z.Dapper.Plus.DapperPlusManager.ValidateLicense(out licenseErrorMessage))
{
    throw new Exception(licenseErrorMessage);
}

// CHECK if the license is valid for a specific provider
string licenseErrorMessage;
if (!Z.Dapper.Plus.DapperPlusManager.ValidateLicense(out licenseErrorMessage, DapperProviderType.SqlServer))
{
   throw new Exception(licenseErrorMessage);
}

Another way to check if your license is valid is simply adding an invalid license instead.

The following error should be raised:

ERROR_001: The provided license key is invalid or trial period is expired. Please buy a product license or go to https://zzzprojects.com and download the latest trial version. License Count: 1
