When selecting an ASP.NET Hosting plan, focus on server resources, support for ASP.NET versions, database support, and scalability. Choose a plan that aligns with your requirements for disk space, RAM, and CPU, and offers options for easy upgrade as your application grows.

To deploy an ASP.NET application, you generally need to: upload your application files to the server using FTP or a control panel, configure IIS to point to your application directory, set up a SQL Server database if required, and test the application to ensure it's running as expected. For detailed instructions, please refer to our knowledge base.

ASP.NET Core is a cross-platform, high-performance framework for building modern, cloud-based, and internet-connected applications. ASP.NET Framework, on the other hand, is limited to Windows and is excellent for building robust and scalable enterprise-level applications.

Key differences include:

• Cross-Platform Support: ASP.NET Core runs on Windows, macOS, and Linux, while ASP.NET Framework is Windows-only.
• Performance: ASP.NET Core is optimized for better performance.
• Modular: ASP.NET Core allows you to include only the necessary NuGet packages, making it more modular.
• Unified MVC & Web API frameworks: ASP.NET Core combines these into a single programming model.

To deploy an ASP.NET application, log into your Plesk Panel, navigate to the 'Domains' section, and follow the deployment wizard. Make sure to upload your compiled application files to the appropriate directory.

In Plesk, navigate to your domain settings and find the 'Hosting Settings' page. Here you can specify custom error documents for your ASP.NET application.

Yes, Plesk allows you to select the version of ASP.NET for each application within the same server, offering flexibility for developers.

Use the Plesk Security Advisor extension to secure your application. Additionally, make sure to follow ASP.NET security best practices like parameterized queries to protect against SQL injection attacks.

Go to the 'Mail' section in Plesk and follow the wizard to create and manage email accounts for your domain.

In Plesk, you can use the 'Resource Usage' statistics to monitor CPU, memory, and bandwidth usage to ensure optimal performance of your ASP.NET application.

You can enable HTTPS by installing an SSL certificate through the Plesk Panel. Once installed, adjust your web.config file to enforce HTTPS.

Optimize your code, utilize caching, and consider using a CDN. Plesk also offers performance optimization tools you can leverage.

In Plesk, navigate to the 'Databases' section and follow the steps to create a new database. Update your application's connection strings accordingly.

Use the Plesk backup manager to take regular backups of both your application files and databases.

Update the ASP.NET version from the server level, and then select the desired framework for each website in Plesk under 'Hosting Settings'.

You can set up custom 404 error pages via Plesk or directly within your application's web.config file.

ASP.NET provides different options like in-process, out-of-process, and SQL Server-based session states. Configure these settings through your application's web.config file.

For scheduling tasks, you can either use the Windows Task Scheduler or integrate with a .NET library like Hangfire for more complex scheduling.
