This is an add-in for Fody which lets you inline methods in compile time.
-
Install the NuGet packages
FodyandInlineMethod.Fody. InstallingFodyexplicitly is needed to enable weaving.PM> Install-Package Fody PM> Install-Package InlineMethod.Fody -
Add the
PrivateAssets="all"metadata attribute to the<PackageReference />items ofFodyandInlineMethod.Fodyin your project file, so they won't be listed as dependencies. -
If you already have a
FodyWeavers.xmlfile in the root directory of your project, add the<InlineMethod />tag there. This file will be created on the first build if it doesn't exist:<?xml version="1.0" encoding="utf-8" ?> <Weavers> <InlineMethod /> </Weavers>
See Fody usage for general guidelines, and Fody Configuration for additional options.
Add the [InlineMethod.Inline] attribute to the methods that you need to inline. Private inline methods will be removed by default. Use [InlineMethod.Inline(false)] to keep them.
What you write:
static unsafe int Read32(void* memPtr) => *(ushort*) memPtr;
[InlineMethod.Inline]
static unsafe int Read32WithInline(void* memPtr) => *(ushort*)memPtr;
public void Test()
{
ulong x = 5;
int y = Read32(&x);
}
public void TestWithInline()
{
ulong x = 5;
int y = Read32WithInline(&x);
