Encountering the dreaded “TypeLoadException: ‘…’ may not beryllium loaded” communication, contempt believing you’ve carried out all the things accurately, is a frustratingly communal education for .Nett builders. This objection sometimes arises once the .Nett runtime can not discovery a circumstantial kind oregon 1 of its dependencies. Piece the mistake communication frequently factors to a lacking implementation, the underlying origin tin beryllium amazingly delicate. This station volition delve into the communal culprits down this objection, providing applicable debugging methods and options to acquire your exertion backmost connected path.
Knowing the TypeLoadException
The TypeLoadException happens throughout the conscionable-successful-clip (JIT) compilation procedure, once the .Nett runtime makes an attempt to burden a kind into representation. This objection tin manifest successful assorted eventualities, together with lacking assemblies, interpretation mismatches, incorrect record paths, oregon equal delicate coding errors. Knowing the base origin is important for effectual troubleshooting.
1 communal origin relates to dependencies. If your task depends connected outer libraries oregon DLLs, guarantee they are accurately referenced and accessible. Different predominant content includes versioning conflicts betwixt antithetic assemblies inside your task.
See a script wherever your exertion references 2 antithetic variations of the aforesaid room. This struggle tin set off a TypeLoadException due to the fact that the runtime mightiness beryllium looking out for a kind successful the incorrect interpretation of the meeting.
Debugging Methods
Figuring out the circumstantial kind that’s failing to burden is the archetypal measure successful resolving a TypeLoadException. The mistake communication normally offers the sanction of the lacking kind. Equipped with this accusation, respective debugging methods tin pinpoint the content.
Archetypal, confirm that the meeting containing the problematic kind is appropriately referenced successful your task. Cheque the task’s properties and guarantee the essential DLLs are included. If you’re running with a analyzable task with aggregate dependencies, see utilizing a dependency direction implement similar NuGet to simplify the procedure.
Adjacent, analyze the meeting binding log. This log supplies elaborate accusation astir the runtime’s makes an attempt to burden assemblies. Enabling the Fusion Log Spectator (fuslogvw.exe) tin shed airy connected binding errors and interpretation conflicts. This implement tin beryllium invaluable for uncovering points associated to meeting redirects.
Communal Causes and Options
Respective communal eventualities set off TypeLoadExceptions. Fto’s research any of these and their corresponding options:
Lacking Assemblies
If the required meeting is lacking from the exertion’s listing oregon the Planetary Meeting Cache (GAC), the runtime received’t beryllium capable to burden the kind. Guarantee the meeting is deployed with your exertion oregon accurately put in successful the GAC. Treble-cheque your task references and physique settings.
Interpretation Mismatches
Conflicts betwixt antithetic variations of the aforesaid meeting tin origin the objection. Usage meeting binding redirects successful your exertion’s configuration record to unit the runtime to usage a circumstantial interpretation of an meeting. This is particularly crucial successful situations wherever you’re utilizing 3rd-organization libraries with analyzable dependencies.
32-spot/sixty four-spot Compatibility
Making an attempt to burden a 32-spot meeting into a sixty four-spot procedure (oregon vice versa) tin pb to a TypeLoadException. Guarantee that the mark level of your exertion matches the structure of the assemblies it makes use of. See utilizing the “Immoderate CPU” mounting once imaginable for most compatibility.
Incorrect Record Paths
If the meeting is positioned successful a listing that the runtime can’t entree, the kind loading volition neglect. Confirm that the meeting is successful the exertion’s listing oregon a determination specified successful the probing way configuration. See utilizing situation variables to negociate paths dynamically.
Precocious Troubleshooting
For much analyzable situations, see utilizing a debugger to measure done the codification and examine the government of your exertion astatine the component of the objection. This permits you to analyze variables and find the direct circumstances that are triggering the TypeLoadException. Moreover, instruments similar Procedure Display tin beryllium invaluable for monitoring record scheme entree and figuring out possible points associated to lacking information oregon incorrect permissions.
- Confirm meeting references and deployment.
- Usage the Fusion Log Spectator to diagnose binding points.
- Cheque the mistake communication for the lacking kind.
- Confirm meeting references successful your task.
- Analyze the meeting binding log.
In accordance to a Stack Overflow study, debugging is 1 of the about clip-consuming duties for builders. Streamlining your debugging procedure tin importantly better your productiveness.
Larn much astir .Nett debugging methods.Featured Snippet: A TypeLoadException frequently signifies that the .Nett runtime can’t find oregon burden a required kind. Communal causes see lacking assemblies, interpretation mismatches, level incompatibility, and incorrect record paths.

Question & Answer :
I’ve received a precise bizarre bug connected our trial device. The mistake is:
Scheme.TypeLoadException: Technique 'SetShort' successful kind 'DummyItem' from meeting 'ActiveViewers (...)' does not person an implementation.
I conscionable tin’t realize wherefore. SetShort is location successful the DummyItem people, and I’ve equal recompiled a interpretation with writes to the case log conscionable to brand certain that it’s not a deployment/versioning content. The bizarre happening is that the calling codification doesn’t equal call the SetShort methodology.
Line - If this reply doesn’t aid you, delight return the clip to scroll behind done the another solutions that group person added since.
Truly abbreviated reply
Delete each your bin and obj directories and rebuild every little thing. The variations of the dlls don’t lucifer.
Abbreviated reply
This tin hap if you adhd a technique to an interface successful 1 meeting, and past to an implementing people successful different meeting, however you rebuild the implementing meeting with out referencing the fresh interpretation of the interface meeting.
Successful this lawsuit, DummyItem implements an interface from different meeting. The SetShort technique was late added to some the interface and the DummyItem - however the meeting containing DummyItem was rebuilt referencing the former interpretation of the interface meeting. Truthful the SetShort methodology is efficaciously location, however with out the magic condiment linking it to the equal technique successful the interface.
Agelong reply
If you privation to attempt reproducing this, attempt the pursuing:
-
Make a people room task: InterfaceDef, adhd conscionable 1 people, and physique:
national interface IInterface { drawstring GetString(drawstring cardinal); //abbreviated GetShort(drawstring cardinal); } -
Make a 2nd people room task: Implementation (with abstracted resolution), transcript InterfaceDef.dll into task listing and adhd arsenic record mention, adhd conscionable 1 people, and physique:
national people ImplementingClass : IInterface { #part IInterface Members national drawstring GetString(drawstring cardinal) { instrument "hullo planet"; } //national abbreviated GetShort(drawstring cardinal) //{ // instrument 1; //} #endregion } -
Make a 3rd, console task: ClientCode, transcript the 2 dlls into the task listing, adhd record references, and adhd the pursuing codification into the Chief technique:
IInterface trial = fresh ImplementingClass(); drawstring s = trial.GetString("dummykey"); Console.WriteLine(s); Console.ReadKey(); -
Tally the codification erstwhile, the console says “hullo planet”
-
Uncomment the codification successful the 2 dll initiatives and rebuild - transcript the 2 dlls backmost into the ClientCode task, rebuild and attempt moving once more. TypeLoadException happens once attempting to instantiate the ImplementingClass.
