### Summary

This Proposal would add a new Roslyn Analyzer: [MemoryAnalyzers](https://github.com/jonathanpeppers/memory-analyzers), a set of Roslyn C# code analyzers for finding memory leaks in iOS and MacCatalyst applications, created by @jonathanpeppers on Microsoft's .NET MAUI team.

### Motivation

The .NET MAUI team adopted `MemoryAnalyzers`, adding it to their code base in this PR: https://github.com/dotnet/maui/pull/16346/files

We should strive to avoid introducing new memory leaks and this analyzer will aid us in avoiding them.

In addition, we strive to mirror the .NET MAUI repo as closely as possible to make it easy for us to promote features from the .NET MAUI Community Toolkit into .NET MAUI. Implementing `MemoryAnalzyers` will ensure our code is production ready for .NET MAUI when the time comes to promote a feature.

### Detailed Design

### Directory.Build.props

We'll set `` for every `MemoryAnalyzer` analyzer

```xml

nullable,CS0419,CS1570,CS1571,CS1572,CS1573,CS1574,CS1580,CS1581,CS1584,CS1589,CS1590,CS1592,CS1598,CS1658,CS1734,MA0001,MA0002,MA0003
```

### Every `CSPROJ` file

In every `.csproj` file, we will add a Private dependency to `MemoryAnalyzers`

```xml

runtime; build; native; contentfiles; analyzers; buildtransitive
all

```

### Device Unit Tests

We will write platform-specific unit tests for iOS, Android, Tizen, Windows and MacCatalyst to ensure that the changes proposed by `MemoryAnalyzers` does not break any existing behavior.

### Usage Syntax

```markdown
N/A
```

### Drawbacks

We are not able to implement this feature until Device Tests are available. I.e. we are currently not able to write platform-specific unit tests for frameworks such as `net7.0-ios`.

### Alternatives

None
