README
## WHY THIS PROJECT IS ARCHIVED - EXPLANATION
------------------------------
MappingGenerator is discontinued in the form of FOSS. I spent the last three months (March 2021 - June 2021) working hard on improving MappingGenerator. I solved many issues and added a bunch of new cool features. I also made a general refactoring which restored the project maintainability. All of that cost me a lot of my private time and I did it all by myself, so I decided to convert MappingGenerator into a commercial product. A perpetual license for a new version of MappingGenerator can be obtained via the official product website https://www.mappinggenerator.net/
I would like to thank all of you who contributed to this product by reporting issues, testing, authoring PRs, or buying me coffee. **PR authors (except the Only README Updaters) and Coffee Buyers will be awarded with a special license for MappingGenerator for free - I will send them an email with details in a few days.**

#### VSCode
Install as a [NuGet package](https://www.nuget.org/packages/MappingGenerator/) or use [this instruction](https://www.strathweb.com/2017/05/using-roslyn-refactorings-with-omnisharp-and-visual-studio-code/) to install from [VSIX](https://marketplace.visualstudio.com/items?itemName=54748ff9-45fc-43c2-8ec5-cf7912bc3b84.mappinggenerator)
### Using along with Resharper
If you are not able to open Roslyn refactoring menu (`ctr + .`) please verify your Resharper settings related to `Visual Studio Integration` or `Visual Studio code analysis` (depends on the R# version). For more information please check [#50](https://github.com/cezarypiatek/MappingGenerator/issues/50)
## Main features
### Generate mapping method body
#### Pure mapping method
Non-void method that takes single parameter
```csharp
public UserDTO Map(UserEntity entity)
{
}
```
#### Updating method
Void method that takes two parameters
```csharp
public void Update(UserDTO source, UserEntity target)
{
}
```
#### Mapping Constructor
Constructor method that takes single complex parameter
```csharp
public UserDTO(UserEntity user)
{
}
```
Constructor method that takes more than one parameter
```csharp
public UserDTO(string firstName, string lastName, int age, int cash)
{
}
```
#### Updating member method
Void member method that takes single parameter
```csharp
public void UpdateWith(UserEntity en)
{
}
```
Void member method with more than one parameter
```csharp
public void Update(string firstName, string lastName, int age)
{
}
```
### Generate inline code for fixing Compiler Errors:
[CS0029](https://docs.microsoft.com/en-us/dotnet/csharp/language-reference/compiler-messages/cs0029) Cannot implicitly convert type 'type' to 'type'
[CS0266](https://docs.microsoft.com/en-us/dotnet/csharp/language-reference/compiler-messages/cs0266) Cannot implicitly convert type 'type1' to 'type2'. An explicit conversion exists (are you missing a cast?)
CS7036 There is no argument given that corresponds to the required formal parameter
## Other mappings
- Complete empty initialization block
- Complete empty initialization block in lambda expression `Expression> = (T) => new T2{}`
- Provide local accessible variables as parameters for method and constructor invocation
- Create missing mapping lambda
- Generate ICloneable interface implementation
## Object scaffolding
## Mapping rules
- Mapping Property-To-Property
```csharp
target.FirstName = source.FirstName;
target.LastName = source.LastName;
```
- Mapping Method Call-To-Property
```csharp
target.Total = source.GetTotal()
```
- Flattening with sub-property
```csharp
target.UnitId = source.Unit.Id
```
- Mapping complex property
```csharp
target.MainAddress = new AddressDTO(){
BuildingNo = source.MainAddress.BuildingNo,
City = source.MainAddress.City,
FlatNo = source.MainAddress.FlatNo,
Street = source.MainAddress.Street,
ZipCode = source.MainAddress.ZipCode
};
```
- Mapping collections
```csharp
target.Addresses = source.Addresses.Select(sourceAddresse => new AddressDTO(){
BuildingNo = sourceAddresse.BuildingNo,
City = sourceAddresse.City,
FlatNo = sourceAddresse.FlatNo,
Street = sourceAddresse.Street,
ZipCode = sourceAddresse.ZipCode
}).ToList().AsReadOnly();
```
- Unwrapping wrappers
```csharp
customerEntity.Kind = cutomerDTO.Kind.Selected;
```
```csharp
public enum CustomerKind
{
Regular,
Premium
}
public class Dropdown
{
public List AllOptions { get; set; }
public T Selected { get; set; }
}
public class CustomerDTO
{
public string Name { get; set; }
public Dropdown Kind { get; set; }
}
public class UserEntity
{
public string Name { get; set; }
public CustomerKind Kind { get; set; }
}
```
- Using existing direct mapping constructor
```csharp
target.MainAddress = new AddressDTO(source.MainAddress);
```
- using existing multi-parameter constuctor
```csharp
this.User = new UserDTO(firstName: entity.FirstName, lastName: entity.LastName, age: entity.Age);
```
