Omnifactotum

Omnifactotum is the ultimate solution for .NET developers who want to streamline their development process. It provides its own helper and functional classes and interfaces as well as the extension methods for the standard .NET types. Omnifactotum is compatible with the older and newer .NET versions. It's the perfect way to reduce errors and save time, allowing developers to focus on creating quality code.

Factotum is a Latin word literally meaning "do everything", that is, a handyman or Jack-of-all-trades.

---

### Changes in 0.7.0 (since 0.6.0)

#### Breaking changes

- **Removed** support of **.NET Framework 4.0**
- `OmnifactotumGenericObjectExtensions`: Removed the `Morph()` methods (null propagation can be used instead)
- Removed the `AsyncFactotum` class in favor of `async`/`await`
- The `OmnifactotumCollectionExtensions.DoForEachAsync()` overloads now accept `CancellationToken` and pass it to `actionAsync`

#### Deprecations

- `Factotum.CreateEmptyCompletedTask()` (use `Task.CompletedTask`)
- `Factotum.CreateEmptyFaultedTask()` (use `Task.FromException(Exception)`)

#### New features

- Extension Methods
 - `OmnifactotumNullableTimeSpanExtensions`:
   - Added the `ToFixedString()` method
   - Added the `ToFixedStringWithMilliseconds()` method
   - Added the `ToPreciseFixedString()` method
 - `OmnifactotumTimeSpanExtensions`:
   - Added the `ToFixedString()` method
   - Added the `ToFixedStringWithMilliseconds()` method
   - Added the `ToPreciseFixedString()` method
 - `OmnifactotumUriExtensions`:
   - Added the `EnsureAbsoluteUri()` method
   - Added the `EnsureWebUri()` method
- Internally added `System.Diagnostics.CodeAnalysis.NotNullIfNotNullAttribute` and `System.Diagnostics.CodeAnalysis.NotNullWhenAttribute` to make these attributes available when targeting older frameworks (prior to .NET Standard 2.1 and .NET 5.0). Affected methods:
 - `OmnifactotumGenericObjectExtensions`
   - `EnsureNotNull<T>()`
 - `OmnifactotumSecureStringExtensions`
   - `IsNullOrEmpty()`
   - `ToPlainText()`
 - `OmnifactotumStringExtensions`
   - `IsNullOrEmpty()`
   - `IsNullOrWhiteSpace()`
   - `IsWebUri`
   - `ToSecureString()`
 - `OmnifactotumUriExtensions`
   - `EnsureAbsoluteUri()`
   - `EnsureWebUri()`
   - `IsWebUri`

#### Minor updates and fixes

- `OmnifactotumGenericObjectExtensions`:
 - Fixed nullability annotations on the `ToPropertyString()` methods
 - Fixed documentation on the `EnsureNotNull()` method
- `OmnifactotumSecureStringExtensions`: Fixed `ContractAnnotation` on the `IsNullOrEmpty()` method
- `OmnifactotumStringExtensions`: Fixed `ContractAnnotation` on the `IsNullOrEmpty()` and `IsNullOrWhiteSpace()` methods
- Applied missing `InstantHandle` annotation on `ObjectValidationResult.GetException(...)`
- Improvements in `OmnifactotumDictionaryExtensions`:
 - Using Nullable Reference Types (where applicable)
 - Applied `AggressiveInlining` (where applicable)
