1.       Introduction Like code is flown into version control system our database scripts will also be flown into the version control system and upgrading and downgrading the system should be straightforward. Before starting the Migration: Every developer should have their own local database for development. They can’t use the shared database for development. -          Steps for Migration Enable Migration This is one-time activity per team. Mostly the team lead when setting up the project will be doing this process. Add-Migration For every new migration activity, we will be using this command to start the migration. Update-Migration After the changes are done and the changes are ready to push to the database. We will use this Update-Migration to push the changes to the database. 2.      Workflow When using migration for a single person it will seem less and easy to use and wo...

Multi-tenancy Models When any application planned to roll out for multiple regions/countries/clients then multi-tenancy model comes into picture. This can be classified into four models as below -        Separate Application Separate Database -        One Shared Application and Separate Database -        One Shared Application and Shared Database (Separate Schema) -        One Shared Application and Shared Database (Same Schema) These models are differentiated based on whether the data is isolated or shared. The difference between the shared data and the isolated data is a continuum with many variations that are possible. Sample Application URL for different implementations. Tenant Name URL Tenant 1 Tenant1.domainname.com Tenant 2 Tenant2.domainnam...

You must have administrative credentials to run regedit.exe. In the Registry Editor, open the following subkey: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full Note that the path to the  Full  subkey includes the subkey  Net Framework rather than  .NET Framework . Note If the  Full  subkey is not present, then you do not have the .NET Framework 4.5 or later installed. Check for a DWORD value named  Release .

The value of the  Release  DWORD indicates which version of the .NET Framework is installed. Value of the Release DWORD Version 378389 .NET Framework 4.5 378675 .NET Frame...

The Powershell comand to send email. $smtpServer = "0.0.0.0" $smtpFrom = "from@gmail.com" $smtpTo = "to@gmail.com" $messageSubject = "Subject of the email" $messageBody = "Body of the email" $smtp = New-Object Net.Mail.SmtpClient($smtpServer) $smtp.Send($smtpFrom,$smtpTo,$messagesubject,$messagebody)

When ever we are struck with the values being not properly filled in the model and need to print all the properties of the model or dto of the page then we can use the below lines of code to loop through the model or dto and write all the items in the page. foreach (var result in Model)             {                                   var type = result.GetType();                     var properties = type.GetProperties();                     <ul>                         @foreach (var property in properties)                         {                         <li>     ...
