Choosing the right data access strategy is a critical architectural decision in any .NET application. Two of the most widely used options are Dapper and Entity Framework Core (EF Core) . This article provides a detailed comparison covering performance, architecture, scalability, maintainability, and real-world usage scenarios. Understanding the Core Difference The primary difference between Dapper and EF Core lies in the level of abstraction they provide. Dapper is a micro ORM that offers minimal abstraction and maximum control. EF Core is a full ORM focused on developer productivity and maintainability. This distinction impacts performance, development speed, and long-term scalability. What is Dapper? Dapper is a lightweight object mapper that works directly with raw SQL queries. It extends IDbConnection and maps query results to C# objects with very little overhead. How Dapper Works Executes raw SQL No change tracking No state management ...

Missing number between array's lowest value and highest value elements in C.             #include <stdio.h> int main ( ) { int arr [ 5 ] = { 2 , 5 , 20 , 18 , 15 } ; int min = arr [ 0 ] , max = arr [ 0 ] , i , j , flag = 0 ; for ( i = 0 ; i < 5 ; i ++ ) { if ( arr [ i ] > max ) { max = arr [ i ] ; //find max value } if ( arr [ i ] < min ) { min = arr [ i ] ; //find min value } } for ( i = min ; i < max ; i ++ ) { for ( j = 0 ; j < 5 ; j ++ ) { if ( i == arr [ j ] ) { flag = 1 ; break ; } else { flag = 0 ; } } if ( flag == 0 ) { printf ( "%d " , i ) ; } } return 0 ; }       ...

 String Caesar Cipher Program in C              It is one of the simplest encryption technique in which each character in plain text is replaced by a character some fixed number of positions down to it. #include <stdio.h> void main() {     char s[50];     int i, j=0, n;         printf("Enter a String: ");     gets(s);     for(i=0; s[i]!=NULL; i++)     {       s[i] = s[i] + 1;     if (s[i] > 'z')          s[i] = s[i] - 26;     }     printf("%s",s); }          Output:-          Here I also change the case of Vowels in Upper Case.(Optional)   #include <stdio.h> void main() {     char s[50];     int i, j = 0, n;   ...
