In my ...\RuntimeCoreNet\resources\shaders\ folder I see that its missing all the shaders with the '_nodecal' prefix. The "_nodecal" shaders don't seem to be present in 200.7.0 so I assume its added in 200.8. I tried clearing my Temp and .nuget folders but it didn't resolve the issue. I'm using .NET ver. 9.0.311 with Maui version 9.0.120.</P><P>Could someone help me figure out whether this is an issue with ArcGIS, Visual Studio, or my setup ?
