Issue while upgrading the application from .Net 8.0 to .Net 10.0

Hi, I am upgrading my API Service Application from .Net 8.0 to .Net 10.0. Below is how the code looks like--

1. There is a Powershell script which deploys the application and below piece of code executes within this script where the error arises (hiding dll name with ** for security concerns).

$scriptBlock = { param ($path, $assemblyPath) function GenerateSecurityMap { param () Add-Type -Path $assemblyPath $map = [**.**.Wcf.SecurityMapProvider]::GetSecurityMap() $jsonContent = $map | ConvertTo-Json -Depth 20 $jsonContent | Set-Content -Path $path } GenerateSecurityMap } $pwshOutput = & pwsh -Command $scriptBlock -Args $jsonPath, $CaiWcfAssemblyPath *>&1 | Tee-Object -Variable realtimeOutput

When the above script get executed in Octopus Deploy, I get the error "Unable to find type "..Wcf.SecurityMapProvider"". This particular assembly gets generated runtime(dynamically) within another assembly (..TestHarness.SecurityMapGenerator) which is based on .netstandard 2.0 like below-->

var sourceCode = $@" using System.Collections.Generic; using System.Text.Json; namespace **.**.Wcf {{ public static class SecurityMapProvider {{ public static Dictionary<string, Dictionary<string, string>> GetSecurityMap() => JsonSerializer.Deserialize<Dictionary<string, Dictionary<string, string>>>(@""{jsonContent.Replace("\"", "\"\"")}""); }} }}"; context.AddSource("SecurityMapProvider.g.cs", sourceCode); //context.AddSource("SecurityMapProvider.g.cs", SourceText.From(jsonContent, Encoding.UTF8));

..TestHarness.SecurityMapGenerator project file code--> <Project Sdk="Microsoft.NET.Sdk"> <PropertyGroup> <TargetFramework>netstandard2.0</TargetFramework> <LangVersion>latest</LangVersion> <EnforceExtendedAnalyzerRules>true</EnforceExtendedAnalyzerRules> <IsRoslynComponent>true</IsRoslynComponent> </PropertyGroup> <ItemGroup> <PackageReference Include="Microsoft.CodeAnalysis.Analyzers"> <PrivateAssets>all</PrivateAssets> <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets> </PackageReference> <PackageReference Include="Microsoft.CodeAnalysis.CSharp" /> <PackageReference Include="Microsoft.CodeAnalysis.CSharp.Workspaces" /> <PackageReference Include="Newtonsoft.Json" PrivateAssets="all"/> </ItemGroup> </Project>

Below are the version of references included in above project-- <PackageVersion Include="Microsoft.CodeAnalysis.Analyzers" Version="5.3.0-2.final" /> <PackageVersion Include="Microsoft.CodeAnalysis.CSharp" Version="4.14.0" /> <PackageVersion Include="Microsoft.CodeAnalysis.CSharp.Workspaces" Version="4.14.0" />

2. Note that the pwsh (powershell) edition in Octopus Deploy is "Windows Powershell(Desktop)"
3. All the above code works fine with .Net 8.0 but fails after upgrading to .Net 10.0
