ASPNETCORE_ENVIRONMENT overwritten on deploy - iis

Question

I have a dotnet core application I am deploying remotely on a test server. The ASPNETCORE_ENVIRONMENT variable should be set to "Development" on the remote machine. Each time I deploy, the ASPNETCORE_ENVIRONMENT variable is overwritten with "Develop". I have to go into the IIS Admin Configuration Editor and replace the incorrect ASPNETCORE_ENVIRONMENT variable each time I deploy.
Can anyone help me understand why this variable is being overwritten each time I deploy?
Here is my web.config file:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<system.web>
<compilation>
<buildProviders>
<remove extension=".xml" />
<add extension=".xml"
type="System.Web.Compilation.ForceCopyBuildProvider" />
</buildProviders>
</compilation>
</system.web>
<system.webServer>
<handlers>
<add name="aspNetCore" path="*" verb="*"
modules="AspNetCoreModule" resourceType="Unspecified" />
</handlers>
<aspNetCore processPath="dotnet"
arguments=".\WorkersCompensation.dll" stdoutLogEnabled="false"
stdoutLogFile=".\logs\stdout" forwardWindowsAuthToken="true">
<environmentVariables>
<clear />
<environmentVariable name="ASPNETCORE_ENVIRONMENT"
value="Development" />
</environmentVariables>
</aspNetCore>
</system.webServer>
</configuration>
Here is my Dev.pubxml file:
<?xml version="1.0" encoding="utf-8"?>
<Project ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
<PropertyGroup>
<WebPublishMethod>FileSystem</WebPublishMethod>

<DeleteExistingFiles>False</DeleteExistingFiles>

</PropertyGroup>

</MsDeploySkipRules>
</ItemGroup>
</Project>

Answer 1

I believe I have found the issue/solution for anyone else having this issue.
The web.config file deployed did not have the environmentVariable entry until I edited the environment variables in IIS Admin.
I altered the web.config and web.Debug.config files in my deploy and now I am getting the correct environment variables on the IIS server.
The web.config file should match the one in my question above, but the web.Debug.Config now looks like this:
<?xml version="1.0"?>
<configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">
<aspNetCore>
<environmentVariables>
<clear />
<environmentVariable name="ASPNETCORE_ENVIRONMENT"
value="Development" xdt:Locator="Match(name)" />
</environmentVariables>
</aspNetCore>
</configuration>
