+Microsoft Patent Promise for .NET Libraries and Runtime Components 
+
+Microsoft Corporation and its affiliates ("Microsoft") promise not to assert 
+any .NET Patents against you for making, using, selling, offering for sale, 
+importing, or distributing Covered Code, as part of either a .NET Runtime or 
+as part of any application designed to run on a .NET Runtime. 
+
+If you file, maintain, or voluntarily participate in any claim in a lawsuit 
+alleging direct or contributory patent infringement by any Covered Code, or 
+inducement of patent infringement by any Covered Code, then your rights under 
+this promise will automatically terminate. 
+
+This promise is not an assurance that (i) any .NET Patents are valid or 
+enforceable, or (ii) Covered Code does not infringe patents or other 
+intellectual property rights of any third party. No rights except those 
+expressly stated in this promise are granted, waived, or received by 
+Microsoft, whether by implication, exhaustion, estoppel, or otherwise. 
+This is a personal promise directly from Microsoft to you, and you agree as a 
+condition of benefiting from it that no Microsoft rights are received from 
+suppliers, distributors, or otherwise from any other person in connection with 
+this promise. 
+
+Definitions: 
+
+"Covered Code" means those Microsoft .NET libraries and runtime components as 
+made available by Microsoft at https://github.com/dotnet/coreclr, 
+https://github.com/dotnet/corefx and https://github.com/dotnet/corert. 
+
+".NET Patents" are those patent claims, both currently owned by Microsoft and 
+acquired in the future, that are necessarily infringed by Covered Code. .NET 
+Patents do not include any patent claims that are infringed by any Enabling 
+Technology, that are infringed only as a consequence of modification of 
+Covered Code, or that are infringed only by the combination of Covered Code 
+with third party code. 
+
+".NET Runtime" means any compliant implementation in software of (a) all of 
+the required parts of the mandatory provisions of Standard ECMA-335 – Common 
+Language Infrastructure (CLI); and (b) if implemented, any additional 
+functionality in Microsoft's .NET Framework, as described in Microsoft's API 
+documentation on its MSDN website. For example, .NET Runtimes include 
+Microsoft's .NET Framework and those portions of the Mono Project compliant 
+with (a) and (b). 
+
+"Enabling Technology" means underlying or enabling technology that may be 
+used, combined, or distributed in connection with Microsoft's .NET Framework 
+or other .NET Runtimes, such as hardware, operating systems, and applications 
+that run on .NET Framework or other .NET Runtimes.
