Unable to resolve dependency 'Syncfusion.Compression.AspNet.Mvc'.

Question

Hi,I have recently rebuilt my Windows laptop and am experiencing no end of problems with reference errors.One I can't seem to get past and doesn't really make sense to me, is Nuget packages failing to install with the following error:One or more unresolved package dependency constraints detected in the existing packages.config file. All dependency constraints must be resolved to add or update packages. If these packages are being updated this message may be ignored, if not the following error(s) may be blocking the current package operation: 'Syncfusion.DocIO.Base 16.3.0.21 constraint: Syncfusion.Compression.AspNet.Mvc (>= 16.3.0.21)', 'Syncfusion.DocIO.Base 16.3.0.21 constraint: Syncfusion.OfficeChart.AspNet.Mvc (>= 16.3.0.21)', 'Syncfusion.OfficeChart.Base 16.3.0.21 constraint: Syncfusion.Compression.AspNet.Mvc (>= 16.3.0.21)'Install-Package : Unable to resolve dependency 'Syncfusion.Compression.AspNet.Mvc'. Source(s) used: 'nuget.org', 'Syncfusion', 'Syncfusion_ASP.NET', 'Syncfusion_ASP.NET Core', 'Syncfusion_WindowsForms', 'Syncfusion_ASP.NET MVC', 'Microsoft Visual Studio Offline Packages'.At line:1 char:1+ Install-Package System.Management.Automation -Version 6.1.0Thing is i'm not even trying to install any syncfusion packages and was trying to install PowerShell script support.Any help would be appreciated in how to resolve.

Hi Steve, 

Thank you for contacting Syncfusion support. 

Starting with version 16.3 (2018 Vol 3), the NuGet package name has been changed for few packages to reflect their functionality on various platforms. To know more about this, kindly refer the following link. 
https://www.syncfusion.com/kb/9337/syncfusion-nuget-packages-updates-not-available-for-latest-version  

Since mentioned NuGet package Syncfusion.Compression.AspNet.Mvc is unavailable(i.e., invalid NuGet name) in the NuGet package sources, the reported error has been encountered. 
 
As you have mentioned “i'm not even trying to install any syncfusion packages and was trying to install PowerShell script support” – So, we request to remove the Syncfusion packages in packages.config file of your application which will resolve the reported error. 

Please let us know if you have any questions.
