Register Syncfusion License key in ASP.NET Core application

19 Apr 20222 minutes to read

Syncfusion license key should be registered, if your project using Syncfusion ASP.NET Core packages refer from nuget.org or from syncfusion installer. The generated license key is a string that needs to be registered before any Syncfusion control is initiated. The following code is used to register the license.

Syncfusion.Licensing.SyncfusionLicenseProvider.RegisterLicense("YOUR LICENSE KEY");
  • Place the license key between double quotes. Also, ensure that Syncfusion.Licensing.dll is referenced in your project where the license key is being registered.
  • Syncfusion license validation is done offline during application execution and does not require internet access. Apps registered with a Syncfusion license key can be deployed on any system that does not have an internet connection.

For ASP.NET Core application using .NET 6.0

Register the license key in the Program.cs file if you created the ASP.NET Core web application with Visual Studio 2022 and .NET 6.0.

var app = builder.Build();
//Register Syncfusion license
Syncfusion.Licensing.SyncfusionLicenseProvider.RegisterLicense("YOUR LICENSE KEY");

// Configure the HTTP request pipeline.
if (!app.Environment.IsDevelopment())
{
    app.UseExceptionHandler("/Error");
    // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
    app.UseHsts();
}

For ASP.NET Core application using .NET 5.0 or .NET 3.1

Register the license key in Configure method of Startup.cs

// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
    Syncfusion.Licensing.SyncfusionLicenseProvider.RegisterLicense(" Your product license key ");
    if (env.IsDevelopment())
    {
        app.UseDeveloperExceptionPage();
    }
    else
    {
        app.UseExceptionHandler("/Error");
        // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
        app.UseHsts();
    }
