Native.NET 1.0.1.5

Generates a processor specific Native Image for an executable and all dependencies and stores them in the cache.

Generating a Native Image can improve performance and load times at the cost of disk space.

Example

static GenerateNative GenerateNative { get; set; } = new GenerateNative();
await GenerateNative.Compile64("INFINITY.exe").ConfigureAwait(false);
GenerateNative = null;

Inline Entire Library

You can inline this with an Action if you want, then you don't need the library, this is actually the preferred method.

/// <summary>
/// Compile Native Image with NGen if it is available
/// </summary>
internal static Action CompileNgen64 = () =>
