C# and .NET Course in Pune with Placement

The procedural base of C#, covered precisely so nothing later rests on a guess. Value and reference types and the difference that actually matters when you assign one variable to another; `var` and implicit typing; constants and `readonly`; and the numeric types with their ranges and conversion rules.

Control flow covers the full set including `switch` expressions, which are the modern form and appear throughout current C#. Methods cover parameters, `ref`, `out` and `in`, optional and named arguments, overloading and expression-bodied members. Arrays close the module alongside `List<T>`, with the honest note that you will use the list far more often.

C# from first principles. Cover the modern C# subset (variables, primitive types, control flow, methods, classes), nullable reference types (the discipline that prevents most C# bugs in 2026), the new top-level statements (no more `static void Main` ceremony), file-scoped namespaces, raw string literals, plus the .NET 9 toolchain — Visual Studio 2026 / VS Code with C# Dev Kit, the dotnet CLI, NuGet for packages, the difference between class libraries / console apps / web apps. By the end of week 2 every student has a working .NET 9 console project with passing tests.

C#'s answer to getters and setters, and one of the things it genuinely does better than Java. Auto-implemented properties, backing fields when you need logic, computed properties, `init`-only setters for immutable-after-construction objects, and required members.

Access modifiers are covered in full — including `internal` and `protected internal`, which most learners never use and every real codebase does. Object initialisers, indexers for classes that behave like collections, and the design judgement that runs through the module: a property should be cheap and side-effect free, and anything that is neither should be a method with a verb in its name.

OOP in C# the way modern teams write it. Classes — properties (including init-only and required), methods, constructors (including primary constructors from C# 12), records (the modern way to write 80% of domain types — value semantics, with-expressions, pattern matching), structs (when value-type semantics matter), abstract classes, interfaces with default implementations, plus the discipline of when to use each. Pattern matching at depth (switch expressions, property patterns, list patterns from C# 11), plus generic types and constraints.

The type-design half of C#. Interfaces including default implementations, explicit interface implementation for name collisions, and the standard interfaces you will implement constantly — `IEnumerable<T>`, `IComparable<T>`, `IEquatable<T>`, `IDisposable`.

Abstract classes against interfaces with a clear rule for choosing, then records — reference and struct — which give value equality, deconstruction and non-destructive mutation with `with`, and are now the right default for DTOs and domain values. Structs and when a value type is genuinely the correct choice close the module, along with the boxing cost of getting that decision wrong in a hot loop.

LINQ is the C# differentiator that separates working code from elegant code. Cover the query syntax vs method syntax (we teach method syntax as the default), the practical operator subset (Where, Select, OrderBy, GroupBy, Join, Aggregate, Any, All, First, Single, FirstOrDefault), deferred execution and the IEnumerable vs IQueryable distinction, plus the Collections world — List, Dictionary, HashSet, Queue, Stack, ConcurrentDictionary, ImmutableArray. We finish by refactoring a 200-line procedural method into clean LINQ.

How C# treats behaviour as data, and the foundation LINQ is built on. Delegates as type-safe function references; `Func`, `Action` and `Predicate`; multicast delegates and their invocation order; and lambda expressions with their closure semantics — including capture of loop variables, which behaves differently from what beginners expect and produces a specific, memorable bug.

Events follow: the publisher-subscriber pattern, `EventHandler<T>`, raising events safely, and unsubscribing — because a subscriber that is never removed keeps its publisher alive and is the most common managed-memory leak in .NET applications.

The model that defines modern .NET. Cover async / await (the right way — never `.Result` or `.Wait()` in production), Task vs Task<T>, ConfigureAwait, cancellation with CancellationToken, exception handling in async code, plus the parallel-work primitives (Parallel.For / Parallel.ForEach, PLINQ when it earns its place, Task.WhenAll for fan-out, Channel<T> for producer-consumer). Plus the discipline of avoiding the most common production failures — async-over-sync, sync-over-async, deadlocks from `.Result`.

Exception handling the modern way — try / catch / finally / using, custom exceptions, exception filters, the discipline of catching specific exceptions over `catch (Exception)`. File and stream I/O — File / Directory / Path / Stream APIs, plus async file I/O for production code. JSON via System.Text.Json (the modern default — Newtonsoft.Json is legacy for new code). Plus the modern-C# features that round out the language — extension methods, delegates and events, lambda expressions, expression trees (briefly), and a primer on Source Generators.

The features that make current C# read very differently from C# of a few years ago, and that a 2026 interview panel expects you to have used. Pattern matching in full — type, constant, relational, logical, property, positional and list patterns — applied through `switch` expressions to replace chains of `if` that were never pleasant to read.

Tuples and deconstruction cover returning several values without inventing a class. Nullable reference types close the module: enabling the feature, reading its warnings, the null-forgiving operator and why reaching for it is usually an admission of defeat, and the migration path for an existing codebase.

How data leaves your program and how frameworks look inside it. `System.Text.Json` for serialisation — options, custom converters, naming policies and the round-trip problems that arise when a property has no setter. XML and binary formats are noted with their current status stated honestly.

Regular expressions cover pattern syntax, the `Regex` class, compiled and source-generated regex. Attributes and reflection then explain the machinery behind ASP.NET Core, Entity Framework and every validation library you will use: reading metadata at runtime, instantiating types dynamically, and the performance cost that makes source generators the modern alternative.

Learn to prove that your C# code works. Cover debugger workflow in Visual Studio or VS Code, breakpoints, watches, call stack inspection, unit testing with xUnit, assertions with FluentAssertions, test naming, test data, mocking awareness, code coverage, nullable warnings, analyzers and refactoring repeated logic. The goal is to make small C# applications reliable before moving into ASP.NET Core or full-stack development.

The design layer that separates a C# developer from someone who writes C#. SOLID taught with concrete examples rather than definitions — single responsibility as a reason to split a class, open-closed through interfaces, Liskov through a substitution that breaks, interface segregation through a fat interface refactored, and dependency inversion as the principle behind every DI container you will use in ASP.NET Core.

Patterns cover factory, strategy, repository, singleton and observer as they are actually written in C#, with an honest note on which are made largely unnecessary by delegates and dependency injection — because reciting patterns is easy and knowing when not to apply one is what interviews reward.

The habits and the project layout that make your work reviewable. Git as collaboration — branching, merging, conflicts, pull requests and a readable history — plus a `.gitignore` that keeps `bin` and `obj` out of the repository, which is the first thing a reviewer notices when it is missing.

Solution structure covers projects, references, and separating a domain library from an application, so the solution reads as an architecture rather than one project with everything in it. NuGet covers packages, versioning and lock files; and code quality covers .editorconfig, analysers and the naming conventions that make C# look like C#.

Round out the C# course with problem-solving and a reviewed language-focused capstone. Practise arrays, strings, lists, dictionaries, sets, stacks, queues, recursion, sorting, searching and basic tree traversal using C#. Then build a console or class-library project that demonstrates OOP, records, LINQ, collections, async file I/O, JSON, error handling and tests. The final repository includes README, screenshots, setup instructions, tests and interview explanation notes.
