Issue: HAXM installation fails due to Intel Execute Disable (XD) Bit capability

Description: While installing Intel HAXM, you may encounter an error regarding the Intel XD support. This error message can be triggered by the following conditions:

  • Intel XD is not supported by your computer�s processor
  • Intel XD is not enabled

Solution:

  • For Intel XD not supported

Intel HAXM requires an Intel processor with Execute Disable (XD) Bit functionality and cannot be used on systems not supporting this hardware feature. To determine the capabilities of your Intel processor, see [official site] (http://ark.intel.com/).

  • For Intel XD not enabled

    Note

    Apple based computers have Intel XD permanently enabled, if the feature is supported by the processor.

If you receive an error message that Intel XD is not enabled, it implies that your computer does not meet the minimum system requirements to use Intel HAXM.In addition, to determine the capabilities of your Intel processor, see official site.

Issue: HAXM installation fails due to Intel Virtualization Technology (VT-x)

Description: When installing Intel HAXM, you may encounter an error regarding Intel VT-x support. This error message can be triggered by the following conditions:

  • Intel VT-x is not supported by your computer�s processor
  • Intel VT-x is not enabled

Resolution:

  • Intel VT-x is not supported

Intel HAXM requires an Intel processor with Intel VT-x functionality and cannot be used on systems lacking this hardware feature. To determine the capabilities of your Intel processor, see official site.

  • Intel VT-x is not enabled

    Note

    Apple based computers have Intel VT-x permanently enabled, if the feature is supported by the processor.

If you receive an error message indicating that Intel VT is not enabled, your computer does not meet the minimum system requirements to use Intel HAXM. To determine the capabilities of your Intel processor, see the official site.

Issue: Visual Studio throws errors when using Tizen.NET.SDK 1.0.0

Description:

Visual Studio Tools for Tizen support Visual Studio 2019 (16.0 or higher version), yet you encounter errors while using Tizen.NET.SDK 1.0.0 or 1.0.1 as shown in the following:

Severity    Code	    Description	Project	File	Line	   Suppression State
Error	  NETSDK1013	The TargetFramework value 'tizen40' was not recognized. It may be misspelled. If not, then the TargetFrameworkIdentifier and/or TargetFrameworkVersion properties must be specified explicitly.	AnalogWatch.Tizen.Wearable	C:\Program Files\dotnet\sdk\2.1.700\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.TargetFrameworkInference.targets	96

Resolution:

This error occurs due to the recent changes in visual studio project system. You can resolve the issue by following either of the options:

  1. Use Tizen.NET.Sdk 1.0.3 Since Tizen.NET.Sdk 1.0.3, Tizen.NET can be used as a custom SDK for MSBuild.

    <Project Sdk="Tizen.NET.Sdk/1.0.3">

<PropertyGroup>
   <OutputType>Exe</OutputType>
   <TargetFramework>tizen40</TargetFramework>
</PropertyGroup>

</Project>

  2. Use Microsoft.NET.Sdk, if you want to continue working with existing Tizen project using legacy Tizen.NET.Sdk. Add the following lines to your csproj file:

    <Project Sdk="Microsoft.NET.Sdk">

<PropertyGroup>
   <OutputType>Exe</OutputType>
   <TargetFramework>tizen40</TargetFramework>
   <!- Workaround: Set TargetFrameworkIdentifier to avoid Tizen TFM issue on VS2019 -->
   <TargetFrameworkIdentifier>Tizen</TargetFrameworkIdentifier> 
   <TargetFrameworkVersion>v4.0</TargetFrameworkVersion>
</PropertyGroup>

</Project>

Issue: Cannot use external library (FSharp.Core.dll) in .NET Core SDK preview version

Description: While trying to use external libraries, you get an error.
