Cannot find type System.Reflection.PropertyInfo in module System.Runtime.dll

[Emanuel]

Hello, after updated Syncfusion UWP components from 16.4.0.52 to 17.3.0.14 when I build the project get the error "Cannot find type System.Reflection.PropertyInfo in module System.Runtime.dll."

Thanks

Hi Emanuel, 

 

Thank you for using Syncfusion controls.   

 

We suspect that you have used Xamarin Forms SfDataGrid. In our end we have changed the following in the Data.portable source. Instead of PropertyInfo you need to give PropertyDescriptor while using the custom aggregate.  

     

public class CustomAggregate : ISummaryAggregate    

{    

              public CustomAggregate()    

              {    

              }    

              public double StdDev { get; set; }    

              public Action<System.Collections.IEnumerable, string, PropertyInfo> CalculateAggregateFunc()    

              {    

                             …    

              }    

}    

 

     

The above method needs to be modified as below.    

     

public class CustomAggregate : ISummaryAggregate    

              {    

                             public CustomAggregate()    

                             {    

                             }    

                             public double StdDev { get; set; }    

                             public Action<System.Collections.IEnumerable, string, PropertyDescriptor> CalculateAggregateFunc()    

                             {    

                                           …    

                             }    

              }

Hi Farjana,

thank you for your info.

In my UWP (native) project I not have a reference to xamarin assemblies.

I added syncfusion references from nuget.

Hi Emanuel, 

 

Thank you for your update. 

 

We have analyzed your query, we have upgrade the Microsoft.NETCore.UniversalWindowsPlatform to 6.2.9 in our source, so only you faced this error when you upgrading the Syncfusion version. So, could you please update your application to 6.2.9 and change the Target version to Windows 10 Fall Creators Update (10.0; Build 16299) or above version. Please refer the below link and screen shot, 

 

https://www.nuget.org/packages/Microsoft.NETCore.UniversalWindowsPlatform/6.2.9 

 

 

 

 

Please let us know if you need any further details on this.
