I am using a demo sample from a class library named Accord.net All the referenses are ok but I get the following error message:
1> All packages listed in D:\Software Projects\Classification (SVMs)\packages.config are already installed.
1>D:\Software Projects\Classification (SVMs)\MainForm.cs(174,42,174,50): error CS1061: 'System.Array' does not contain a definition for 'GetRange' and no extension method 'GetRange' accepting a first argument of type 'System.Array' could be found (are you missing a using directive or an assembly reference?)
1>D:\Software Projects\Classification (SVMs)\MainForm.cs(177,37,177,46): error CS0117: 'Accord.Math.Matrix' does not contain a definition for 'Cartesian'
1>D:\Software Projects\Classification (SVMs)\MainForm.cs(178,17,178,23): error CS0122: 'Accord.Math.Vector' is inaccessible due to its protection level
1>D:\Software Projects\Classification (SVMs)\MainForm.cs(179,17,179,23): error CS0122: 'Accord.Math.Vector' is inaccessible due to its protection level
I can not modify the protection level of those classes to e.g public as I do not have access to them. What can I do to let this compile?

Can someone help me resolve this error? I downloaded the Hangfire v1.7.18 from GitHub and I get the following error when I add/edit a key/value in the Strings.resx file.
The error is thrown on line 42 and specifically on this part - typeof(Strings).Assembly
and it looks like it is happening for .netstandard 1.3. Here is the complete error:
Error|CS1061| ‘Type’ does not contain a definition for ‘Assembly’ and no accessible extension method ‘Assembly’ accepting a first argument of type ‘Type’ could be found (are you missing a using directive or an assembly reference?) in Project Hangfire.Core (netstandard1.3) The file is src\Hangfire.Core\Dashboard\Content\resx\Strings.Designer.cs at Line 42
I have an MVP c# application where I have an SQLLite database for development purposes and a SQLServer database for deployment purposes. Whenever I try to build it with the SQL server database, it shows: "Build failed."
I am a student Informatica and our teacher says that we could solve our problem by using a simple "if else" to switch between development and deployment but we have no idea how.
We have already used dependency injection and migrations.
