Translating .Net Core Web Applications

[dcarlstedt]

I'm having issues getting successful translations to complete without errors for my .net core web applications. The errors that I"m seeing are all related to the translator not being able to translate foreach loops within our code.

Code that will trigger the error

int[] values = new int[] { 1,2,3,4 };
foreach (int v in values)
{
     // code here
}

Translation Error

[warning]: Translation errors occurred during execution of .Net translator: Failed to translate method GetHeaderAndBase64Decode at C:\git\WebAPI\Source\Application.WebAPI\Controllers\DiagnosticsController.cs:167:8

If I change out the foreach loop into a for loop the translation error is fixed, however that is not ideal.

Here are the parameters I'm sending to sourceanalyzer to perform the translation which happens after I build (DEBUG) and restore packages:

• -dotnet-core-version 2.1
• -aspnetcore
• libdirs **/* **/*

Here is what I've tried to resolve this:

• changing -dotnet-core-version to the runtime version I'm using which is 2.1.8
• changing -dotnet-core-version to the sdk version I'm using which is 2.1.50

The command I'm running

sourceanalyzer.exe -b 123 -verbose -debug -logfile sca_binaries_logfile.txt -aspnetcore -dotnet-core-version 2.1 -libdirs **/* **/*

My questions:

• How can I fix these translation errors?
• Where's the documentation specifying which version numbers are accepted for -dotnet-core-version, -dotnet-standard-version
• Do you see anything wrong with what I'm doing on the command line when calling source analyzer?
