# Kernel - NKS0037

This analyzer provides the following strings:

<table><thead><tr><th width="174">Context</th><th>String</th></tr></thead><tbody><tr><td>Error List</td><td>Caller uses <code>Environment.OSVersion.Platform == PlatformID.Win32NT</code> instead of <code>KernelPlatform.IsOnWindows()</code></td></tr><tr><td>Suggestion Box</td><td>Use <code>KernelPlatform.IsOnWindows()</code> instead of <code>Environment.OSVersion.Platform == PlatformID.Win32NT</code></td></tr><tr><td>Description</td><td><code>KernelPlatform.IsOnWindows()</code> is more readable and less verbose than <code>Environment.OSVersion.Platform == PlatformID.Win32NT</code>.</td></tr></tbody></table>

### Extended Description

This code analyzer detects the comparison of `Environment.OSVersion.Platform` against the `Win32NT` value.

`Environment.OSVersion.Platform` is an ancient way of determining the current operating system that Nitrocid is running on. As a result, it doesn't implement the macOS operating system detection, since it was considered as Unix.

As a result, `KernelPlatform` implements a handful of platform detection functions to allow you to more accurately detect your platform. Also, it simplifies the complicated platform checking statements to its simpler equivalent.

### Analysis Comparison

To get a brief insight about how this analyzer works, compare the two code blocks shown to you below:

#### Before the fix

<pre class="language-csharp" data-title="Somewhere in your mod code..." data-line-numbers><code class="lang-csharp">public static void MyFunction()
{
<strong>    bool value = Environment.OSVersion.Platform == PlatformID.Win32NT;
</strong>}
</code></pre>

#### After the fix

<pre class="language-csharp" data-title="Somewhere in your mod code..." data-line-numbers><code class="lang-csharp">public static void MyFunction()
{
<strong>    bool value = KernelPlatform.IsOnWindows();
</strong>}
</code></pre>

### Suppression

You can suppress this suggestion by including it in the appropriate place, whichever is convenient.

### Recommendation

We recommend that every caller which use this function use the recommended abovementioned method.
