Register Syncfusion License key in Blazor Application
22 Mar 20233 minutes to read
Syncfusion license key should be registered, if your project using Syncfusion Blazor packages reference from nuget.org or from trial installer. The generated license key is just 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");
NOTE
- 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.

var app = builder.Build();
//Register Syncfusion license

// 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();
}
// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
