Error in pipeline "Failed to create importer 'BitmapFontImporter'

Extended
4

I did some digging, after updating to Content Pipeline v3.7.0 from v1.1.0 with NuGet, this is what I get when executing build command manually:

H:\Visual Studio\Projects\Test\Test\Content>"C:\Program Files (x86)\MSBuild\MonoGame\v3.0\Tools\MGCB.exe" /@:"H:\Visual Studio\Projects\Test\Test\Content\Content.mgcb" /platform:Windows /outputDir:"H:\Visual Studio\Projects\Test\Test\Content\bin\Windows" /intermediateDir:"H:\Visual Studio\Projects\Test\Test\Content\obj\Windows"

Build 2 succeeded, 1 failed.

Time elapsed 00:00:00.14.

After plumbing around with a debugger I’ve managed to print out what’s going on internally:

Unhandled Exception: System.MissingMethodException: Method not found: 'Microsoft.Xna.Framework.Content.Pipeline.ContentStatsCollection MonoGame.Framework.Content.Pipeline.Builder.PipelineManager.get_ContentStats()'.
   at MGCB.BuildContent.Build(Int32& successCount, Int32& errorCount)
   at MGCB.Program.Main(String[] args)

The exception is thrown by MonoGame.Framework.Content.Pipeline.Builder.PipelineManager.ResolveAssemblies()

My project targets .NET 4.7.2, my MonoGame version is 3.7.1 (was tested on 3.7.0 as well), my MonoGame.Extended version is 3.7.0 - NuGet latest at the time of writing.

What’s baffling is that this property exists in the decompiler view :confused:

EDIT:
Here’s some more info on the subject, as it seems assemblies are being loaded from a directory where lib from NuGet is located. I’m even more confused as I keep getting the feeling that it’s a user fault?
Call stack: > MonoGame.Framework.Content.Pipeline.Builder.PipelineManager.ResolveAssemblies( - Pastebin.com
Contents of LoaderExceptions at the top of the call stack: - LoaderExceptions {System.Exception[0x0000000F]} System.Exception[]+ [0] {S - Pastebin.com

EDIT 2:
Looks like I’ve solved the problem for myself. I had to manually add the following to the mgcb file.

/reference:..\..\packages\MonoGame.Extended.3.7.0\lib\netstandard2.0\MonoGame.Extended.dll
/reference:..\..\packages\MonoGame.Extended.Tiled.3.7.0\lib\netstandard2.0\MonoGame.Extended.Tiled.dll
/reference:..\..\packages\MonoGame.Extended.Content.Pipeline.3.7.0\lib\netstandard2.0\MonoGame.Extended.Content.Pipeline.dll

That got it building again.

However, after doing that, I was experiencing the issue that got solved in here:
